MIST TMR25 RTD Temperature Transmitter

Brand: Intempco Controls, Inc.

INTEMPCO TMR25 temperature sensor employs a Pt100 Class A resistance temperature detector (RTD) combined with an integrated loop-powered 4-20 mA output transmitter.

Electrical connection to the TMR is Hirschmann (DIN 43650) plug. This sensor is rugged and all Stainless Steel 316 construction.

Fittings, 1/4" to 1" NPT welded to tube, are available for mounting purposes. An adjustable bore-through compression fitting option is also available.

This allows for easy adjustment of desired immersion depth. The unit is factory calibrated to customer temperature requirements.
