Cryogenic NTC Thermistors

Amphenol Advanced Sensors  Cryogenic NTC Thermistors are designed  for use in the range of 77°F (room temperature) to -320.8°F (the boiling point of Liquid Nitrogen) (25°C to -196°C). These thermistors demonstrate exceptional stability without exhibiting hysteresis effects and remain unaffected by rapid temperature cycling in terms of their electrical, thermal and mechanical properties. The Negative resistance/Temperature Co-efficient (NTC) thermistors may be used at temperatures below the Nitrogen Point with suitable instrumentation as well. The cryogenic thermistor probes consist of a pressed disc thermistor attached to #27 AWG silver lead wires.  These devices are well-suited for cryogenic control applications, such as liquid levels in the 77°F to -320.8°F (25°C to -196°C) range. Other typical applications include temperature measurement/control and compensation, surge suppression, fluid-level detections and customised solutions.
