NTC Type JW, JC Thermometrics Clip-On Pipe and Surface Sensors 

## **Features** 

- Suitable for use in conditions of high condensation and occasional immersion in water 

   - Self-adjusts to irregular pipe surfaces 

   - Fast time response (1.5s typical) for JC and 3.0s for JW 

- 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.) 

- 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** 

## Type JW Specifications 

## **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** 

- Other resistance - temperature characteristics

- Special pipe sizes 

## **General Data** 

- Minimum operating temperature: 32°F (0°C) 

- Maximum temperature: 212°F (100°C) (sensor) 185°F (85°C) (housing) 

- Dissipation factor: ≥2mW/K (mounted on copper pipe at 77°F (25°C)) 

- Isolation voltage: 500 VDC 

- Clip force: <50N for mounting / de-mounting on pipe 5N will not cause rotation on pipe 

- Shoe material: Plated brass 

- Body material: Nylon
