Headmount Transmitters

Models HMMV, HMPO, HMPT and HMTC are fully analogue 2-wire ‘hockey puck’ transmitters for in-head mounting.

These low cost, high accuracy transmitters offer good stability and ease of setting. Inputs types may be PT100 RTD's, thermocouple types J, K or T, millivolts or potentiometers. Coarse span selection is made by solder links and fine trim by top accessed multi-turn potentiometers.
