4. Function

LS-10: Submersible pressure transmitter for level measurement, standard version.
LH-11: Submersible pressure transmitter for level measurement, High Performance.
Function: The hydrostatic pressure prevailing within the application is transformed into a stan-
dardised 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 hydrostatic pressure and can be evaluated correspondingly.

WIKA Operating instructions/Betriebsanleitung/Mode d'emploi/Instrucciones de servicio LS/LH-10
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 (e.g. with
dangerous media such as acetylene, flammable gases or liquids and toxic
gases or liquids and with refrigeration plants or compressors). 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.
Open circuit before removing connector / cover.
