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.)
• 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
• Self-adjusts to irregular pipe surfaces
• Fast time response (1.5s typical) for JC and
3.0s for JW
