Application
The device Hydrocont K with integrated analogue evaluation electronic is a compact transmitter for continuous
measuring of fill levels and temperatures in liquids at hydrostatic pressures from -1 up to 20 bar within pressure
less container, also in explosive hazardous areas, at process temperatures from – 20°C to +140°C.
The use of a capacitive measuring sensor with ceramic membrane, allows the use in nearly all fields of industry,
especially in hygienic applications.
Application fields are e.g. water, waste water, solvents, oil, sludge, fat, cleaning liquids, etc.
By using suitable materials like PEEK, FEP or also FFKM, the device can also be used at applications with
especially aggressive liquids.
Function
The device Hydrocont K is sunken down into the liquid by the carrying cable or mounted by the respective
process connection into the wall of the container or pipe
Measuring principle
The device Hydrocont B is used for filling level measurement by measuring the hydrostatic pressure.
The height of the liquid column over the measuring membrane causes on the measuring membrane the
so-called hydrostatic pressure, that is defined besides the height of the liquid column also by the density of the
liquid and the gravitational constant.

Characteristics of the ceramic measuring membrane
The hydrostatic pressure of the liquid is applied to the ceramic membrane and causes there a variation of the
capacity at the back side of the membrane.
A pressure transmitting liquid is not used.
The ceramic membrane offers excellent characteristics like highest pressure and pressure blow strength up to
eighty times the nominal pressure, vacuum resistance, very high resistance against chemicals, corrosion and
abrasion as well as very good insensitiveness against temperature shocks, highest accuracy and reproducibility,
good long term stability and a very low temperature influence.
Characteristics of the process diaphragm seal – high temperature variant – type H
The hydrostatic pressure of the liquid is applied to the metallic membrane of the process diaphragm seal and is
transmitted by a pressure transmitting liquid to the ceramic measuring membrane that is placed behind.
This leads among others to a extension of the permissible medium temperature up to +140°C.
Signal processing
The filling level proportional hydrostatic pressure signal of the ceramic membrane is measured by the integrated
analogue electronic and converted in a output current signal of 4…20mA.
The measuring signal range can be adjusted corresponding to the requirements of the application in a wide
range for measuring range zero and end value.
Furthermore an influence of the measuring signal by an adjustable damping for neutralization of short pressure
blows or also for calming down cyclic fluctuating pressure signals is possible.
Integrated over voltage protection components prevents the filling level sensor from destruction by atmospheric
influences like e.g. thunderstrike.

requirements (contacting substances, process temperature). An unsuitable material can lead to damage,
abnormal behavior or destruction of the device and to the resulting dangers.
The device meets the legal requirements of all relevant EC directives.
Safety notes for electrical operating supplies
for explosive hazardous areas
If a device is installed and operated in explosive hazardous areas, the general
Ex construction standards (EN60079-14, VDE0165), this safety notes and the enclosed
EC conformity certificate must be observed.
The installation of explosive hazardous systems must be carried out principally by specialist staff.
The device meets the classification:
II 1/2 G Ex ia IIC T4 Ga/Gb
II 2 G Ex ib IIC T4 Ga
The devices are conceived for measurement of filling levels in explosive hazardous areas.
The measured medium may also be combustible liquids, gases, fogs or steams.
The permitted operating temperatures and pressures are type and variant dependent and can be found in this
technical manual.
For applications, which require devices of category 1/2, the process pressure and
temperature range of the media has to be between 0,8 bar and 1,1 bar and between -20 °C and 60 °C.
The device with over voltage protection Hydrocont Ex1K_ _ _2... is earthen for safe technical function. Provide
sufficient potential compensation along the complete cable way.
Connect the PA-clamp in the connection housing with the potential compensation of the explosive hazardous
area. Install the intrinsically safe circuit earth free.
At variants of the devices with chargeable plastic parts (e.g. connection housing, cable), a warning marking
points out to the safety measures, that must be applied because of the electrostatic charging in operation and
especially in the case of maintenance activities.

Installation
The installation of the device at locations where high pressure blows can occur should be avoided.
The installation of the device should be made if possible at temperature calmed places to get a reliable
measuring result. Large temperature steps, e.g. at filling of a hot medium into a cold system, can produce a
short-time higher measuring signal deviation at the variants with ceramic measuring membrane.
At a large amplification of the measuring signal this deviation will be also amplified accordingly.
The deviation will be completely neutralized after the adaptation of the measuring membrane of the filling level
transmitter to the temperature.
At a step from +20°C ...+80°C this neutralization can wile up to 3 minutes.
The use of a process diaphragm seal can cause an essential improvement.
The installation position has influence on the measuring result of the kind of a zero value shift because of the
deadweight of the measuring membrane and a possible pressure transmitting liquid. This deviation can be
eliminated by an offset adjustment. Zero and end value must be shifted by the same amount.
Drive the system pressure free prior installation resp. deinstallation of the sensor.
The tightening of the process connection with screw-in thread may only be done at the hexagon by a suitable
spanner.
The maximum permitted torque strength is 50 Nm.
The screw in of the process connection by using the housing tube is not permitted.
Avoid the pollution of the pressure compensation vent. The hindrance of the pressure compensation can lead to
faulty measuring results.
For simplifying the system sided cable run the connection head can be arbitrary rotated after installation of the
device.
After the opening of the housing at first the electronic module must be removed.
By this the two screws, that fixes the electronic module must be released.
At pulling out the electronic module take care that the sensor cables that are connected at the bottom side of
the electronic module will not be damaged or detached.
Loosen now the three screws below and rotate the connection head into the desired orientation.
After that, fix the three screws again.
The electronic module must be inserted now and fixed with the two screws.
The correct function of the device within the specific technical data can only be guaranteed, if the permitted
temperature in the area of the connection housing (see technical data) will not be exceeded.
This can be achieved by the using a process diaphragm seal (high temperature variant – type H), by isolation of
the liquid carrying part of the plant or by other constructive measures to reduce the transferring of an extreme
temperature to the connection housing.
A process diaphragm seal (high temperature variant – type H) together with the measuring transmitter forms a
closed, calibrated system, that is filled by openings in the process diaphragm seal and in the measuring system
of the measuring transmitter. These openings are sealed and may not be opened.
Maintenance
The device is free of maintenance.
Special substances can lead to solid coatings on the membrane.
Such depositions can lead to faulty measurement results of the device.
In the case of coat forming liquids the membrane must be regularly cleaned e.g. with clear water.
Don’t use sharp tools or aggressive chemicals for cleaning.
Repair
A repair may only be carried out by the manufacturer.
If the device must be sent back for repair, the following informations must be enclosed:
 An exact description of the application.
 The chemical and physical characteristics of the product.
 A short description of the occurred error.
Before returning the device for repair, the following measures must be proceeded:
 All stick product residues must be removed. This is especially important, if the product is unhealthily, e.g.
caustic, toxic, carcinogenic, radioactive etc.
 A returning must be refrained, if it is not possible by 100% to remove the unhealthily product completely,
because e.g. it is penetrate into cracks or is diffused through plastic.

Electrical connection
The electrical connection of the device must be carried out according to the respective country specific
standards.
Incorrect installation or adjustment could cause applicationally conditioned risks.
Use only twisted shielded signal and measurement wires and install these wires separated from power leading
wires. Connect the cable shield only at one side to earth, ideally at the installation place of the device.
The earthing of the cable shield of an connected cable can be done at the installation place of the connection
housing by using the terminal PE. At the variant with plug M12x1 the earthing of the cable shield must be done
at the evaluation side of the installation.
The metallic parts of the device (probe housing, screwing thread of the connection housing) are electrically
connected with the terminal PE in the connection housing. The socket of the plug M12x1 is not connected to the
other metallic parts of the device.
The cable gland is suitable für cable diameter from 7 to 13 mm.
After the installation of the cable the cable gland must be firmly screwed to ensure the tightness of the
connection housing. The same is valid for the housing cap.
The voltage applied to the plug contacts may not exceed 45 V, to avoid damage of the electronic.
All connections are polarity protected.
A load, e.g. the measuring shunt of an evaluation device, in series with a device with 4...20 mA current signal in
2-wire-technology reduces the supply voltage available at the device. This results in a maximum value for this
resistor, where a correct function is still possible.
The maximum load at signal current 20mA can be calculated by the equation:
RL max = (VS – 12,5V) / 20mA with VS = applying supply voltage.
For inauguration it is suggested, to deactivate all connected control devices, to avoid unwanted control
reactions.

Operation elements - adjustment
Adjustment trimmer zero value resp. end value
For adjustment of the measuring range at zero and end value.
For simplifying the procedure a current measuring device can be connected to the terminals 1 and 2 without the
need to disconnect the measuring circuit.
A turn to the right increases the output current. At a turn to the left the output current will be decreased.
Procedure at adjustment:
 Set liquid to the minimum filling level and adjust a signal current of 4mA with the zero value trimmer
(zero).
 Set liquid to the maximum filling level and adjust a signal current of 20mA with the end value trimmer
(span).
 At large measuring range variations it could be necessary to repeat the zero and end value adjustment
one or two times, because the variation of the potentiometer adjustment at zero and end value
produces additionally an influence the respectively other value.
The adjustment range is limited to
 Maximum zero value increasement to 25 % of the nominal measuring range
 Minimum measuring range 25 % of the nominal measuring range
Adjustment trimmer damping
For adjustment of the damping of the measuring signal.
For neutralization of short pressure blows or also for calming down cyclic fluctuating pressure signals, produced
by mixing machines or also at fill-in.
A turn to the right increases the damping time constant.
At a turn to the left the damping time constant will be decreased.
Without damping the device responses to pressure changes within milliseconds.
At the maximum damping the complete transmission of a pressure change to the output signal can be delayed
by approx. 25 seconds in an exponential function.
