electrical and pressure-measuring devices. The installer is responsible for performing the
installation in accordance with these instructions and with the electromagnetic compatibility and
safety regulations and standards applicable to the type of installation.
- The device should be configured appropriately for the purpose for which it is to be used.
Incorrect configuration may cause erroneous functioning, leading to damage to the device or an
accident.
- If a device is not functioning correctly, disconnect it and send it for repair to the manufacturer or
to a firm authorized by the manufacturer

installed or used in particularly unfavourable conditions, where the following dangers occur:
- possibility of mechanical impacts, excessive shocks and vibration;
- excessive temperature fluctuation, exposure to direct sunlight;
- condensation of water vapour, dust, icing.
Installation of intrinsic safety versions should be performed with particular care, in accordance with
the regulations and standards applicable to that type of installation.
The technical manual (DTR) contains parameters for the probes which were correct at the time of going to
press. These parameters may be changed.
The manufacturer reserves the right to make changes (not having a negative impact on the operational
and metrological parameters of the products) without updating the contents of the technical manual.

For power supply with rectangular characteristic:
Supplementary attentions:
The supply of power from a source with a rectangular characteristic means that the voltage of the
Ex power supply remains constant until current limitation activates.
The protection level of power supplies with a “rectangular” characteristic is normally “ib”.
The probe powered from such a supply is also a Ex device with protection level “ib”.
Example of practical provision of power supply with a rectangular characteristic:
use a stabilized power supply with Uo=24V with protection level „ib” and current limited to 25mA < Io < 30mA
6.1. The protection level
The probe is Ex device with protection level „ia” when the powered circuit have protection level „ia”.
The probe is Ex device with protection level „ib” when the powered circuit have protection level „ib”.

1. INTRODUCTION
1.1. This manual is intended for users of SGE-25.SMART, SGE-25S.SMART, SGE-25, SGE-25S, SGE-25C
and SGE-16 hydrostatic level probes containing the data and guidelines necessary to understand the
functioning of the probes and how to operate them. It includes essential recommendations concerning
installation and use, as well as emergency procedures.
1.2. The SGE-25, SGE-25S and SGE-25SMART, SGE-25S.SMART are also made in Ex version.
Additional data on the probes in Ex version is contained in the appendix designated
„DTR.SG...04 (ENG). Appendix.Ex.04” or „DTR.SG...04 (ENG . Appendix.Ex.03”.
During installation and use of the probes in Ex version, reference should be made to DTR.SG...04 in
conjunction with Appendix Ex.
1.3. The level probes: SGE -25, SGE -25S, SGE -25C, SGE -25SMART, SGE -25S.SMART in
realization for sea uses are complied with Det Norske Veritas (DNV) Rules for Classification of Ships,
High Speed & Light Craft and Det Norske Veritas' Offshore Standards. Certificate No. A -11311 for
application in following Location Classes: Temperature C, Humidity: B, Vibrations: B, EMC: B,
Enclosure: D.
2. USER MATERIALS
Probes are delivered in single and/or multiple packs. A probe is delivered together with a “Product Certificate”
which also serves as a guarantee card.
Each batch of probes also carries user’s manual in quantities agreed with the customer .
3. APPLICATIONS OF PROBES
The SGE-25.SMART, SGE-25S.SMART, SGE-25, SGE-25S, SGE-25C and SGE-16 probes are designed to
measure the depth of liquid in wells, swimming pools, watercourses, boreholes etc.
The SGE-25S.SMART and SGE-25S probes are also designed for the measurement of levels of liquid waste
and of dense or viscous.
The SGE-16 probe, due to its small diameter, is designed fir the measurement of water levels in wells and
boreholes, wherever it is necessary to insert probes into pipes of small diameter for which it is impossible to
use the SGE-25.
The 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 (probes SGE-25, SGE-16, SGE-25C, SGE-25S) and a digital communi-
cation signal in the „HART” system (probes SGE-25.SMART, SGE-25S.SMART),or in special versions into a
0÷10V signal transmitted in a three-wire system (applicable only to the SGE-25, SGE-25S, SGE-25C models).
Probes fitted with cables with an additional Teflon shield may be used with food products and with reactive
substances.
4. IDENTIFYING MARKS. ORDERING PROCEDURE
4.1. Identifying marks on a rating plate
Every probe carries a rating plate containing at least the following information: CE mark, numbers of notified
institutions and designations of certificates obtained, name of manufacturer, type, factory number, basic
