3. APPLICATIONS OF PROBES
The SGE-25.SMART, SGE-25S.SMART, SGE-25C.SMART, SGE-25S.SMART/TITAN, SGE-25, SGE-25S,
SGE-25 and SGE-16 probes are designed to measure the depth of liquid in wells, tanks, watercourses,
boreholes etc.
The SGE-25S.SMART and SGE-25S probes are particularly designed for the measurement of levels of liquid
waste and of dense or viscous.
The SGE-16 probes, due to their small diameter, are designed for the measurement of water levels in wells and
boreholes, wherever it is necessary to insert probes into pipes of small diameter.
Probes fitted with cables with anadditional Teflonshieldmay be used with food productsand with reactive substances.
The SGE-25, SGE-16, SGE-25C, SGE-25S probes convert an input pressure (being a measure of the level of the
medium) into a standard 4÷20 mA signal transmitted in a two-wire system, or in special versions into a 0÷10V
signal transmitted in a three-wire system.
The SGE-25.SMART, SGE-25S.SMART, SGE-25C.SMART, SGE-25S.SMART/TITAN probes generate
a 4÷20mA output signal and a digital HART signal in a two-wire system (current loop).

6. TECHNICAL DESCRIPTION
6.1. Principles of Operation
The hydrostatic level probes work by converting changes in the resistance of a piezoresistive bridge, which
are proportional to the pressure (of a hydrostatic column of liquid), into a standard current output signal.
The active sensing device is a silicon diaphragm with in-diffused piezoresistors.
6.2. Construction
6.2.1. The probe is composed of the active sensing device with silicon and sealing diaphragm, and plate with
the electronic components.
The SGE-25S.SMART and SGE-25S probes are additionally fitted with a diaphragm seal enabling measuring
the depth of dense media and media with suspended matter and impurities, such as liquid waste (fig. 1, 3).
The output signal is passed through a special cable with a capillary used to connect the negative side of
the measuring diaphragm to the atmosphere.
6.2.2. Special versions of the probes can be produced with cables shielded by an additional teflon layer.
The shield covers the parts of the cable while is immersed in the medium being measured, as well as
a necessary additional segment.
The Teflon shield (in Ex version) is additional equipped in stainless steel cord escorted electrostatic charges
(see fig. 5).
6.2.3. The probes are fitted with elements ensuring excess voltage protection: „transil” diodes between the
wires, and plasma surge arresters between the wires and the casing.
The plasma surge arresters are assembled in normal and "Version SA" only.
6.3. Electronic circuit of the probes
Electronic circuit can be produced in two versions:
6.3.1. The digital version (SGE-25.SMART and SGE-25S.SMART probes).
The electronic circuit changes the signal from the sensing module into digital signal and input to
a microprocessor, which controls the probe’s operation. Using data input during the production process,
the processor processes the conversion curve, adjusts for thermal errors and carries out linearization.
After processing, the digital signal is again converted into an analogue 4÷20mA current signal, with
a superimposed digital communication HART signal.
6.3.2. The analog version (SGE-25, SGE-25S, SGE-25C and SGE-16 probes).
The electronic circuit changes the signal from the sensing module into an output signal 4...20 mA.
The electronic circuit is equipped in filter elements assured resistance on conducted and radiated disturbances
and electric impulse.
7. PLACE OF INSTALLATION
7.1. The level probes installed in places where liquid levels are measured in wells, tanks, boreholes etc. The
probe is immersed in the medium being measured. A special cable extends above the level of the medium;
this can be connected directly to another device or to a terminal box.
7.2. High and Low Ambient Temperatures and Medium Temperatures
When measuring liquids whose solidification point is above the ambient temperature, the medium should not
be allowed to freeze around the probe, this applies in particular to water in the case of open-air installations.
For maximum medium temperatures see sect. 5.
Data for versions Ex in accordance with Appendix Ex.03, Appendix Ex.04.

E3 14 DTR.SG...05(ENG)
8. INSTALLATION AND CONNECTION
8.1. Mechanical Installation
The probe can be suspended from the power supply cable e.g. using the handle SG prod. Aplisens.
If the probe will often be removed or, when during the pull, there is the possibility of hitching protruding
elements it is recommended to suspend the probe on a steel cable using the supporting handle (not applicable
to SGE-16). If the cable is to be exposed to current or turbulence, it should be installed in a protective tube,
e.g. one made from PCV.
Directly before location the probe in measured medium to take off from diaphragm seals
SGE-25S, SGE-25S.SMART, SGE-25C the securing covers.
Protect the level probe from impacts during installation.
The probe with an additional Teflon shield suspends on a steel cable or on an internal cable (do not
catch for teflon).
The probe in Ex-version with a cord for earthing suspend on a steel cable using the lifting handle.
8.2. Electrical Connection
The method ofmaking electrical connections is shown in figure 2, 3A, 4A (forEx version in figure 3 „Appendix Ex”).
If the transmission line leads to remote premises via the open air, it is recommended that a terminal box
be fitted, e.g. the Aplisens type PP, in order to connect the probe’s cable to the remaining section of the
transmission line. The box should have an IP65 ingress protection rating, and but should not be so airtight as
to prevent the probe’s active sensing device from “breathing” via a capillary embedded in the cable.
The opening of the capillary should not be allowed to become dirty, and water should not be allowed to enter
the capillary.
Where the transmission line is very long, it is recommended that the section leading from the end of the probe
cable be made from twisted pair cable, and it is desirable that entry points to other devices be fitted with
excess voltage protection, e. g. the Aplisens UZ-2 system.
The cable of the probe and the remaining section of the transmission line should be protected from
mechanical damage.
From the probe power supply is led cable screen (green wire). The manufacturer recommends connecting the
probe cable shield to the ground point measuring system; grounding of the cable shield is particularly
appropriate in an environment of large EMC; e.g. the pumping station when the cable passes the test probes
power cable supply pump. Cable shield in work station with battery may, but need not be grounded.
9. SETTINGS AND REGULATION
9.1. Settings of SGE-25, SGE-16, SG-25C, SGE-25S probes
The SGE-25, SGE-16, SGE-25C, SGE-25S are factory set to the range stated in the order. The user does not
have access to the “zero” and “range” potentiometers. Setting may be adjusted by the manufacturer only.
9.2. Settings of SGE-25.SMART, SGE-25S.SMART, SGE-25S.SMART/TITAN
probes
The SGE-25.SMART and SGE-25S.SMART probes are equipped with a smart electronic and HART
communication system, thought which the user can make e.g. set „zero” and measurement ranges.
9.3. SGE-25.SMART, SGE-25S.SMART, SGE-25S.SMART/TITAN.
Measurement ranges. Definitions
9.3.1. The maximum range of level, while the probe can measure is called „basic range” (for specifications
of “basic range” see 5.1.1).
The width of the basic range is the difference between the upper and lower limits of the basic range.
The internal characteristic conversion curve for the basic range is coded in the probe’s memory.
This is the reference curve used when making any adjustments which affect the probe’s output signal.
9.3.2. When the probe is in use the term “set range“ is used.
The set range is the range whose lower end-point corresponds to an output current of 4mA and whose upper
end-point corresponds to a current of 20mA (or 20mA and 4mA respectively when the conversion curve
inverted). The set range may cover the whole of the basic range or only a part of it. The width of the set range
is the difference between the upper and lower limits of the set range. The probe may be set to any range
within the basic range of level values, subject the restrictions set out in the table in 5.1.1.

E3 15 DTR.SG...05(ENG)
9.4. Configuration and Calibration
9.4.1. The SGE-25.SMART, SGE-25S.SMART, SGE-25C.SMART, SGE-25S.SMART/TITAN probes have
features which enable metrological and identification parameters to be set and altered. The configurable
metrological parameters affecting the probe’s output signal include the following:
a) Unit in which the measured level is expressed on the display;
b) Upper end-point of the set range;
c) Lower end-point of the set range;
d) Time instant;
e) Type of characteristic curve: linear or radical.
Parameters of an informational nature which cannot be altered include the following:
a) Upper limit of the basic range;
b) Lower limit of the basic range;
c) Minimum set range.
9.4.2. Other identification parameters, not effecting the output signal, include: device address, device code,
factory identification code, factory device code, number of preambles (3÷20), UCS, TSD, program version,
electronics version, flags, factory number, label tag, description tag, date tag, message, record number,
sensing module number.
The process of setting the parameters listed in 9.4.1 and 9.4.2 is called “Configuration”.
9.4.3. It is possible to adjust the probe’s zero point, for example to compensate for deviation resulting from
a change in position of installation.
The probes may also be calibrated, by taking readings with the input pressure controlled using a standard
device. These process and zero-point adjustments are called “Calibration”.
9.4.4. Configuration and Calibration of the probe are carried out using an Aplisens KAP-03 or KAP-03Ex
communicator, certain HART communicators or a PC with HART/RS232 converter and Aplisens “Raport2”
software.
Catalogue cards and user manuals for Aplisens communication tools (KAP communicator, HART/RS232
converter and “Raport 2” programme) can be found on the manufacturer website www.aplisens.pl.
After configuration it is important to protect the transducers using command HART [247].
During work probe should be safe prior to entries. This prevents accidental or intentional
changes configurational data. The protection function is accessible in KAP-03 communicator,
“Raport2” software, as well as, in applying DD or DMT programs libraries.
10. INSPECTIONS, REPAIRS AND SPARE PARTS
10.1. Regular inspections
10.1.1. Regular inspections should be carried out in accordance with the regulations to which the user subject
An inspection should be made of the external condition of the probe, during which:
a) Check that there are no signs of mechanical damage in the form of impact marks or dents;
b) Check the condition of the cable, which should not show signs of wearing, bending or fraying of the
external coating; check the condition of the packing gland.
Every two years or in accordance with regulations applicable to the user, check the zero point (4mA).
10.1.2. Check the „zero point” (SGE-25, SGE-25S and SGE-25C) bring the probe up above the surface of
the liquid and read the output current. In case of excessive deviation of the zero reading, return the probe to
the manufacturer for adjustment of the conversion curve or adjust the zero point of a device used
in conjunction with the probe (e.g. monitor, regulator, and controller).
10.1.3. Check the „zero point” SGE-25.SMART, SGE-25S.SMART, SGE-25S.SMART/TITAN see 10.1.2.
10.2. Additional Inspections
If the probe is installed in a place where it might have been subject to mechanical damage, wearing cable
covering, excess pressure, hydraulic impulses, sedimentation, crystallization or erosion of the diaphragm,
or excess electrical voltage, inspections should be made as necessary.
Check the state of the diaphragm and cable, clean the diaphragm, and check the zero point.

E3 16 DTR.SG...05(ENG)
10.2.1. Faults in the Transmission Line
If there is no current in the line or the value of the current is random, check the transmission line,
the connections with the terminal adapters, connectors etc.
If the transmission line is in good order, check whether the probe is functioning correctly.
10.2.2. Protection from Excess Voltage
The probe may be in danger from excess voltage caused by connection faults or atmospheric electrical
discharge.
Protection from excess voltage between the wires of the transmission line is provided by TVS diodes installed
in all types of probe (see the table, column 2).
In order to protect against excess voltage between the transmission line and the casing or earth
(not prevented by the diodes connected between the transmission wires), additional protection is provided in
the form of plasma surge arresters (see the table, column 3).
Also external protective devices may be used, e.g. the UZ-2 Aplisens system, or others.

series
68V DC
Plasma surge arresters - 230V DC
(only in normal and “SA”versions)
The voltage in the protective elements must not exceed the maximum permitted values given in columns 2 and
3 of the table.
The insulation test voltages 500V AC or 750V DC refer to transmitters with plasma surge arresters.
In case of a large surge of excess voltage between the wires of the line, thesafety diode may sustain damage due
to a low-resistance short circuit (a diode damaged in this way still provides protection to the probe’s circuits).
Symptoms of damage:
- When the probe is connected to the power supply, the value of the current exceeds 20 mA, and the
voltage on the probe is of an order of several hundred mV (in extreme cases a particularly strong
surge may cause circuits or wires inside the probe to burn out; the current is then 0 mA and there is
full voltage in the output circuit);
- When the probe is not connected to a power supply, the resistance of the probe should be measured;
this is approximately 10and is equal to the value of the limiting resistors + resistance of the
damaged diode.
Damage to the gas-filled spark gap (Plasma surge arresters) is much less likely than damage to the diode, and
may lead to a short circuit or a lowering of the resistance of the spark gap.
10.2.3. Damage Caused by Overpressure
Another possible reason for malfunctioning of the probe is damage caused by overpressure, which may result
from such factors as
a) Freezing of the medium;
b) Dynamic effects of a strong current of liquid on the diaphragm seal while the probe is being washed
(applies mainly to the SGE-25S, SGE-25S.SMART model);
c) Striking or scraping of the diaphragm with a hard object, such as a screwdriver.
If excess pressure on the probe has caused damage to the silicon or sealing diaphragm, the probe can
no longer be used. Symptoms of such damage are generally such that the output current falls below 4 mA or
rises above 20 mA, and the probe fails to react to input pressure.
10.2.4. Cleaning the Diaphragm Seal
Impurities which have accumulated on the diaphragm during operation should not be removed by mechanical
means such as scraping, scrubbing etc., as this may cause damage. The only permitted method is to dissolve
the impurities, possibly aiding their removal with a light brush.
Sedimentation on the diaphragm may affect the conversion curve.
After removing sedimentation, parts which have come into contact with the solvent substance
should be thoroughly rinsed, and the health and safety regulations relating to the chemical
in question should be adhered to.
Do not use substances which might cause corrosion of the diaphragm seal.

10.3. Spare Parts
The following parts of the probe can be replaced when worn or damaged: cable, seals on the packing gland.
The cable may be replaced by the manufacturer only.
11. PACKING, STORAGE AND TRANSPORT
11.1. Packing, Transport
The probes should be packed in such a way as to protect them from damage during transportation, in single or
multiple packs. The cable should be rolled into a loop 300 mm in diameter, secured so as to prevent the coils
from moving relative to each other and the whole from moving within the package. Avoid breakage to the
cable at the point where it enters the packing gland. Land, sea or air transport may be used, provided that
direct action of atmospheric effects is prevented.
11.2. Storage
The probes should be stored in multiple packs under cover, in a place free of vapours and reactive
substances, with temperature and humidity not exceed the limits for specific probes.
12. GUARANTEE
Manufacturer warrants under the conditions specified in the Product Certificate which is also a guarantee card.
13. SCRAPPING, DISPOSAL
Waste or damaged probes should be dismantled and disposed of in accordance with Directive (2012/19/UE)
on waste electrical and electronic equipment (WEEE) or returned to the manufacturer.
