A temperature sensor consists of a MJS or MJD thermistor leaded and sealed with insolating, thermal conducting and fireproofing material dependent on environment. The configuration and dimension can be adjusted to be easy for installation and detection. *Features: 1. Wide operating temperature range, good stability and reliability. 2. Easy to installation and manipulation as the sealing can be done according to environment and conditions there it is applied by customer. 3. Accurate testing can reflect temperature change precisely. 4. Insulating resistance: more than 100 5. Working temperature range(Celsius): -40 to +125 6. Dissipation factor(mW/Celsius): 2.6-5 (in still air) 7. Thermal time constant(S): 25-65 (in air) *Application: 1. Refrigerator, frozen cabinet, air conditioner, microwave oven, electric brooder 2. Water heater, dishwasher, bread maker, disinfecting machine, soybean milk machine 3. Thermostat, foster-mother, grill oven and so on
