Amphenol Thermometrics NTC Type Waterproof Clip-On Pipe and Surface Sensor JW/JC Series

Thermometrics Type JW/JC of Waterproof Clip-On Pipe and Surface Sensors are NTC or PTC type chip thermistors on a ceramic/metal shoe assembly sealed in a polymer housing and provided with flexible twin cable connections. The housing is fitted with a spring metal clip for pipe attachment. Suitable for use in conditions of high condensation and occasional immersion in water. Typical applications include gas boiler control, domestic water systems, air conditioners, radiator inlet-outlet, electric showers and vending machines.
