Caution
2-wire Two connection lines are intended for the voltage supply.
The supply current is the measurement signal.
3-wire Two connection lines are intended for the voltage supply.
One connection line is intended for the measurement signal.
UB Positive supply connection
S+ Positive measurement connection
0V Negative supply connection

4. Function

The pressure prevailing within the application is transformed into a standardised electrical
signal through the deflection of the diaphragm, which acts on the sensor element with the
power supply fed to the transmitter. This electric signal changes in proportion to the pressure
and can be evaluated correspondingly.

WIKA Operating instructions/Betriebsanleitung/Mode d'emploi/Instrucciones de servicio HP-1/HP-2
Select the appropriate pressure transmitter with regard to scale range,

!
performance and specific measurement conditions prior to installing and
starting the instrument.
Warning
Observe the relevant national regulations (e.g.: EN 50178) and observe the

applicable standards and directives for special applications. If you do not
observe the appropriate regulations, serious injuries and/or damage
can occur!
Open pressure connections only after the system is without pressure!
Please make sure that the pressure transmitter is only used within the overload threshold
limit all the time!
Observe the ambient and working conditions outlined in section 7 „Technical data".
Ensure that the pressure transmitter is only operated in accordance with the provisions i.e.
as described in the following instructions.
Do not interfere with or change the pressure transmitter in any other way than described in
these operating instructions.
Remove the pressure transmitter from service and mark it to prevent it from being used
again accidentally, if it becomes damaged or unsafe for operation
Take precautions with regard to remaining media in removed pressure transmitter.
Remaining media in the pressure port may be hazardous or toxic!
Have repairs performed by the manufacturer only.
Please be aware of the fact that within a system under pressure the maximum pressure for
the complete system is determined by the component with the lowest admissible opera-
ting pressure, even when there are single components that can be operated with higher
pressures. When a wide range of pressures is expected within a measuring system, all
connected components must be able to withstand the highest possible pressure peaks.
Take appropriate protective measures to prevent parts from being ejected in
the case of faults. Ensure that these protective devices cannot be removed
without using tools.
