Field Controls 2002 Thermistor Thermistor

Thermistor

The Field Controls 2002 Thermistor is an electrical device that changes resistance depending on the temperature of the surrounding environment.

The FisMaster Field Controls 2002 Thermistor thermistor is a temperature-sensitive resistor that allows for precise control of current.

Precise temperature control is vital for the field calibration of thermistors. Our Thermistor products provide a tightly controlled 1°C temperature rise over the entire 4-20 mA process input range. We offer three J and K type thermistors with accuracy within ±0.15% of the platinum resistance standard at an ambient temperature of +23°C (±0.2°C).

Touchscreen Thermistor controls for heater and A/C units. These fit most Fedders, Bradford White, Lennox Goodman and other brand central air conditioning and heater packages. Fits single stage 70 volt controls only .  SSB122 $18

A thermistor is a resistor whose resistance changes significantly with temperature, by as much as several thousandfold over some range of temperatures. This effect is used in devices that measure temperature, and also in devices called thermistors used as adjustable resistors.  Temperature sensors and thermistors are found in many electronic devices (e.g., oven thermostat, lorry exhaust gas thermocouple) for use in control circuits.

Here is the datasheet for the thermistor we used in this project. At room temperature it's resistance will be about 2K ohm, and rise to 70K or so as it warms up to working temperature.
