4. Function and accessories
N-10: Pressure connection (non-incendive) with internal diaphragm (standard version).
N-11: Pressure connection with flush diaphragm (non-incendive) for highly viscous or
solids entrained media which might clog the pressure port.
2-wire Two connection lines are intended for the voltage supply.
The supply current is the measurement signal.
3-wire Two connection lines are intended for the voltage supply.
One connection line is intended for the measurement signal.
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.
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.

Remove the female connector. Open
the pressure transmitter by detaching
the clamping nut (see Fig. A ). Carefully
remove the male connector from the case.
Adjust the zero point (Z) (see Fig. B ) by
generating the lower limit of the pressure
range.
Adjust the span (S) by generating the
higher limit of the pressure range.
Check the zero point.
If the zero point is incorrect, repeat proce-
dure as required.
Reassemble the instrument carefully.
Make sure all sealings and o-rings are not
damaged and correctly installed to assure
the rated moisture ingress protection.
