Monitor Temperatures inside an enclosure

monitor temperatures inside an enclosure

Looking for a simple, low cost way to monitor temperatures inside an enclosure ?

Acromag’s ST132-0600 temperature transmitter is compact, inexpensive and provides a loop powered 4-20mA output and is able to monitor temperatures inside an enclosure.

Acromag’s ST132-0600 Thermocouple/Millivolt Input 2-Wire Transmitter a tiny, puckstyle unit is only 4.5cm in diametre 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 sensors are 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!

The ST132-0600 has advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile temperature measurement device. These transmitters can withstand harsh industrial environments and operate reliably across a wide temperature range with very low drift. They feature RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions.
