Description
The RG.SN.5022 is an NTC (Negative temperature coefficient) temperature sensor. The resistance of the sensor element decreases with increasing air temperature. It is designed as a fluid temp sensor and is not recommended for air temperature due to a slower response time. It is an unpowered sensor and therefore requires that the input line is pulled up, so that the resistance change will result in a voltage drop in the input pin. It is generally recommended to connect the sensor to an AT input on a MoTeC device, as these inputs include a 1kΩ pullup to 5V.

Thread: 1/8 NPT
The voltage information below is provided assuming the sensor is setup on an input including a 1kΩ pullup resistor to 5V. If this is not the case, then the resistance row must be used to calibrate the sensor instead.
