Applications
On return air ducts to measure heating/cooling return air
On supply air ducts to measure heating/cooling supply air
In heat exchangers and air handling units to control heating/cooling coils for temperature and humidity control
As frost protection sensor

Temperature Sensor
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 or a platinum film sensor or a thin nickel layer on a ceramic substrate. Its resistance changes according to the temperature.
