SRA-T - Indoor


Passive temperature sensor for indoor mounting

The sensor measures the temperature by use of a NTC, PT or NI-sensing element. The sensing element is either a glass packed thermistor with a negative temperature coefficient, a platinum film or a nickel thin layer based probe. Its resistance changes according to the temperature. The change follows a specified curve.


Indoor temperature measurement


  • Thermistor, NI and PT sensing elements to fit your system
  • Simple and secure installation
  • Wide range of temperature probes
