Temperature probe resists moisture

Betatherm's moistureproof probe has been developed as a solution for a wide range of applications where proof against moisture is required.
After time, temperature is measured more than any other variable in our world today.
Given the pervasiveness of temperature sensing and measurement needs, it is therefore not surprising that temperature sensors are required to detect, measure and control temperature in a wide number of environments.
In particular, when sensors are used in low temperature applications (eg -50C), free-thaw applications (eg refrigeration) or water immersion applications (eg swimming pools, spa, etc), the insulation characteristics of the temperature sensor itself are of huge importance.
When exposed to such environments any moisture ingress affects the electrical behaviour of the sensor and as a result the accuracy and reliability of its performance.
Betatherm's moistureproof probe has been developed as a solution for a wide range of applications where proof against moisture is required.
These include refrigeration applications (including evaporator coil and industrial case refrigeration), under-floor heating systems, climate control systems, swimming pools, sauna and oceanographic equipment.
Based on NTC thermistor technology, this overmoulded design is available as standard in both thermoplastic (24AWG) and stainless steel (316) housing.
Tested to 10,000 freeze thaw thermal cycles and exhibiting moisture proofness to environmental standard IP68, other features and benefits include: an operating range from -50 to +150C; time response of 7s in water; a range of resistance curves and tolerances; and the availability of custom-length cables.
