Product description
3.1 Mounting description
Instructions for mounting:
When mounting the instrument, ensure that the sealing faces of the in-
strument and the measuring point are clean and undamaged.
Screw in or unscrew the instrument only via the flats using a suitable tool
(fixed spanner, wrench size 27mm) and the prescribed torque. The ap-
propriate torque depends on the dimension of the pressure connection
and on the sealing element used (form/material).
A maximum torque of 50 Nm must not been exceeded. Do not use the
case as working surface for screwing in or unscrewing the instrument.
When screwing the transmitter in, ensure that the threads are not
jammed.
As described in the installation example the sealing (
GDZ-28
) must be
made at the face surface of the pressure connection.

3.3 Operating and Maintenance Advice
a.) You must only use the sensor with GMH 3111 - ex, GMH 3151 - ex or GMH 3156 - ex devices!
Usage of other devices may result in destruction of sensor and device.
b) Treat sensor and device carefully. Use only in accordance with above specification. (do not throw, hit against etc.).
Protect plug from soiling.
c) To disconnect pressure sensor adapter cable from the device do not pull at the cable but at the plug (to open
lock).
When connecting the sensor make sure that arrows are pointing upwards and that plug is entered into device
socket centrally. Do not twist plug when entering socket.
If plug is entered correctly, it will slide in smoothly
If plug is twisted or entered incorrectly the connecting pins of the plug can be spoilt by bending or broken
=> Plug can no longer be used and connecting cable needs to be replaced.
