Introduction: Temperature Sensor is made with high precision, reliable NTC Thermistor connected to PVC wire, which is wrapped with insulated, heat conductive and water resistant materials into desired shapes, so as to facilitate long-distance temperature measurement and control and installation. CWF51 series are non-epoxy resin temperature sensor, featuring moisture protection, good insulation, high reliability, little time constant, and sensitive response, designed for use in household air-conditioners, refrigerators, and so on. Application: For temperature measurement and control of household and car air conditioners, refrigerators, freezers, water heaters, drinking water dispenser, air warmers, dishwashers, disinfecting cabinets, washing machines, driers, medium-low-temperature drier cabinet, thermo tanks, and so on. Features: New technique adopted to ensure stable performance and long working hours (yearly excursion rate of resistance:Equal or smaller than 0.1 percent). High precision of resistance and B value:Negative or positive 1%) Good coherence and interchange ability. Quick response and high delicacy. Double packaging techniques adopted to ensure good insulation and sealing effect, high resistance to mechanical colliding and bending. Convenient for pacing as per the practical condition. The traditionally-structured sensor could be made into high dissipation product, which test current could be far larger and circuitry be simplified.
