AEM Electronics Fluid Temperature Sensor Kits are designed to provide a highly accurate and responsive oil/water temperature measurement.Accuracy: < 1.5°C / 2.7°FOperating Temp: -20C to 150C / -4F to 302FDissipation Constant: 12 mW/°C. The ratio, at a specified ambient temperature, of the change in the power dissipation of the sensor to the resultant temperature change of the thermistor. Test medium: silicone oil.Thermal Time Constant: 10 sec. The time required for the sensor to achieve 63.2% of its steady-state value when subjected to a step-change in ambient temperature [Tc=(Tf-Ti)*63.2%+Ti]. Test medium: silicone oil.Sensor Body Material: BrassThread: 1/8" NPTHex Size: 1/2"Installation Torque: 13.5Nm / 10 ft-lbsWeight: 10gElectrical Termination: Weatherproof High-Performance DTM-Style connector. Includes Mating Connector, Pins & Wire SealsIncludes: Water Temp Sensor High-Performance DTM-Style, 1/8" NPT Aluminium Bung, Mating Connector, Pins & Wire SealsThis fluid temperature sensor
