GENERAL

TRX10H is a head mounted high performance, "all-in-one" 2-wire temperature transmitter. Its high reliability industrial design offers some rare functions, e.g. 4~20 mA or 20~4 mA selection.

TRX10H with Pt100 input is adjustable for 8 overlapping ranges in °C or °F and gives a temperature linear output. All selections are made by solder jumpers. 'Fine' ZERO / SPAN potentiometers are provided for calibration.

The flat design gives easy access to terminal & adjustments. The large central hole lets the lead wires or an insert tube pass easily.
