4. Function
Ultra High Purity Transducer
WUC-10: Single End
WUC-15: Flow Through
WUC-16: Modular Surface Mount
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

WARNING!
■
Select the appropriate transducer with regard to scale range, performance and specific measurement condi
-
tions prior to installing and starting the instrument.
■
Consider the relevant national regulations (e.g.: EN/IEC 60079-14) 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 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 transducer 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 transducer is only operated in accordance with the provisions i.e. as described in the following
instructions.
■
Do not interfere with or change the transducer in any other way than described in these operating instructions.
