Spectrum Sensors and Controls introduces a ruggedized sensor for monitoring temperature in challenging applications, such as high moisture environments where the sensor is subject to continuous freeze/thaw cycles. The sensor's thermistor element is isolated from not only outside moisture, but also the high stress of freezing and thawing through a unique, swaged end design that provides an excellent moisture seal between the cable and housing. This ruggedized temperature sensor delivers quick response and excellent thermal tracking and is ideal for HVAC, food and beverage and refrigeration system applications.

Spectrum's new ruggedized temperature sensor has been tested to 10,000 freeze/thaw thermal cycles, is waterproof to IP68 and has a wide operating temperature range of –40°C to 105°C. The sensor features standard resistance values ranging from 2,252 to 10,000 Ω at 25°C with a wide variety of thermistor curves and resistances available to meet customers requirements. Standard cable length is 3 ft. with optional lengths and terminals available, and the sensor can be used with Spectrum's Clip-On assembly for 3/8" and 1/2" copper pipes.

Spectrum's ruggedized temperature sensor is designed to address ice build up, a common occurrence in many HVAC, appliance, refrigeration and food service appliances. In a standard temperature sensor, water can generally breach the end seal of the probe therefore allowing the ice to exert a significant force on the wire or cable. Once the water has penetrated the housing, subsequent freezing and thawing cycles help provide a direct moisture path to the thermistor element.

Spectrum's ruggedized temperature sensors are priced at $4.75 each @ 5,000 pieces.
