Squirrel Input Type : U

· Temperature Measurement using Thermistors

U inputs are intended for use with Thermistor temperature sensors.

  • Thermistors (2 KOhm at 25ºC) provide a large exponential value change of resistance with change of temperature, offering high sensitivity but over a limited temperature range.
  • Unlike some other temperature sensor types, the cable resistance does not significantly affect accuracy of measurement.
  • Note that Squirrel U inputs are also completely compatible with type UU sensors. Type UU sensors offer greater accuracy than type U sensors.

Ranges available in the Squirrel data logger:

Min temp Max temp Units Resolution Modules M01, M01A, M01B, M02 Resolution Module M16
