Water Temperature Sensor – 1/4″-18NPT Thread – 120C Temp Range These resistive temperature sensors are built in a housing of brass. All sensors come with a sensor output and an insulated ground pin. The two connections are interfaced through the metal plate connectors. The sensors can be applied in a wide field of applications.Features:Function – Oil temperature, coolant temperatureLength – 28.5mm (1-1/8″)Thread – 1/4″-18NPTCalibration – 120CMeasurement Range – 120COutput Signals – ResistiveIP67Insulated ground pin
