Clip-on Pipe and Surface Sensor - Type JW/JC

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.

Suitable for use in conditions of high condensation and occasional immersion in water
Low temperature gradient (<1.8°F at 140°F (<1°C at 60°C))
Sensing element electrically isolated from shoe (isolation >20M Ω at 500V)
Range of clips for pipe diameters
0.51 in to 1.18 in (13 mm to 30 mm)
Self-adjusts to irregular pipes
Offers cost benefits over traditional immersion probes
Fast response times - 1.5s typical for JC and 3.0s typical for JW
Type JW (water resistant version) meets IP46 standard (with connector tabs encapsulated)
