4. Function

Ultra High Purity Transducer
WU-10: Single End; WU-15: Flow Through; WU-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

5. For your safety

Select the appropriate transducer 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!

Warning
toxic!
Disconnect the instrument before connecting up to the power supply.
„
Make sure that all parts are protected against direct contact when installing
„
the device and making connections.
Configure the system with particular care when connecting up to other equipment.
„
„ 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.
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
Have repairs performed by the manufacturer only.
„
The operator is responsible for the material compatibility as well as correct handling,
„
operation and maintenance.
The safety of the user can be detrimentally influenced by the equipment if
„
e.g.: - visible damage is apparent
- it cannot be operated any longer as stipulated
- it has been stored over a longer period under unsuitable conditions.
In cases of doubt the device should be returned to the manufacturers for repair and
servicing.
Information about material consistency against corrosion and diffusion can be found in our
WIKA-Handbook, 'Pressure and Temperature Measurement'.
