Features
- Suitable for use in conditions of high condensation and occasional immersion in water
- 0 - 100°C operating range
- 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)
- Type JC meets IP44 standard
- Range of clips for pipe diameters 0.51 in to 1.18 in (13 mm to 30 mm). (Consult factory for additional size options.)
- Self-adjusts to irregular pipe surfaces
- Fast time response (1.5s typical) for JC and 3.0s for JW
- Water resistant version (Type JW) meets IP46 standard (with connector tabs encapsulated)
- Offers cost benefits over traditional immersion probes
- Typical applications include gas boiler control, domestic water systems, air conditioners, radiator inlet-outlet, electric showers, vending machines, chiller and refrigeration units Amphenol Advanced Sensors
Description
NTC or PTC chip thermistor 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. Options
