NTC THERMISTORS: TYPE JC CLIP-ON PIPE SENSOR DESCRIPTION: A range of temperature sensing elements on a ceramic / metal shoe assembly and held in a polymer housing and provided with connector tabs. The housing is fitted with a spring metal clip for pipe attachment. A water resistant version is also available, incorporating a foam seal and sealed wire outlet holes. The elements available are NTC, PTC, SLN (silicon linear PTC) and PRT (Pt). FEATURES: * Fast time response (1.5s typical) * Low temperature gradient (<1C at 60C) * Sensing element electrically isolated from shoe * * * * * DIMENSIONS: Housing length (isolation >2M at 500V) Water resistant version meets IP44 standard (with connector tabs encapsulated) Range of clips for pipe diameters 13 to 30mm Self-adjusts to irregular pipes 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 (along pipe) = 16mm GENERAL DATA: Minimum operating temperature ............ 0C Maximum temperature .......... 100C (sensor) .............................................. 85C (housing) Dissipation factor ........................... 2mW/K ..................
