For Your Safety - WIKA E-10 Betriebsanleitung

4. Function / 5. For your safety
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 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.

Information about material consistency against corrosion and diffusion can be found in our
WIKA-Handbook, 'Pressure and Temperature Measurement'.
