TMA - Temperature Transmitters


  • High accuracy
  • 4-20 mA loop powered
  • Rugged, all 316 SS construction
  • -200 to 600°C temperature range
  • Custom designs available
  • Accessible zero & span



TMA temperature sensor employs a Pt100 class B resistive temperature detector (RTD) combined with an integrated loop powered 4-20 mA output transmitter. Optional digital indicator, model AUF, plugs directly to the Hirschmann (DIN 43650) plug. This sensor is rugged and all 316 SS construction. Fittings, 1/4” and 1/2” 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. Recalibration via zero and span potentiometers, at the connector, is possible.
