Low Cost Inside Box Temperature Sensor Application

ST132-0610 Thermocouple/Millivolt Input 2-Wire Transmitter

Wixom, MI: – June 20, 2018: If you need a simple way to monitor temperatures inside an enclosure, Acromag’s ST132-0610 temperature transmitter is compact, inexpensive and provides a loop powered 4-20mA output. The tiny, puckstyle unit is only 1.75 inches in diameter and easily scaled for -40 to 80°C input. Just mount the transmitter inside your panel and jumper short the input terminals to measure ambient temperature without a sensor. Then wire the 4-20mA output to your PLC, DCS, Controller, or Recorder. You now have a low cost box temperature sensor with 4-20mA output proportional to -40 to 80°C inside the box. No thermocouple or other sensor is necessary. This approach uses the internal cold-junction compensation sensor within the ST132 transmitter as the ambient temperature sensor. The ST132 is highly accurate, stable, and best of all, low cost! All trademarks are the property of their respective owners.
