Mounting the HMP143A
The cable model HMP143A should also be mounted with the sensor head
horizontally whenever possible. This model is provided with two plastic nuts
and a gasket. Mount the nuts on the sensor head: disconnect the cable from the
transmitter, insert the nuts and fasten them on the sensor head. Then reconnect
the cable. A mounting flange is also available (see Fig. 3.2.3). The cable can
also be extended up to 100 metres; see Appendix 3 for details.
