of severe injuries due to
catapulting parts.
Warning
Potential danger of burns
due to hot surfaces.
Caution
2-wire Two connection lines are intended for the voltage supply.
The supply current is the measurement signal.

4. Function

IS-10: Pressure connection (intrinsically safe) with internal diaphragm (standard version).
IS-11: Pressure connection with flush diaphragm (intrinsically safe) for highly viscous or
solids entrained media which might clog the pressure port.
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.

 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.
Consider the details given in the EC-type examination certificate as well
as the respective specifications for explosion hazard use of the country
concerned (e.g.: IEC 60079-14). If you do not observe these stipulations,
Warning
serious injuries and/or damage can occur.
