880-00048/ PD121222 96℃ NPT3/8 Engine Coolant Water Temperature Gauge With Alarm for Boat Ship

This is the universal type of switch widely used on ships，boats, yacht etc， Install on radiator or cooling system piping. Bimetallic disk is a kind of sensor element that changes its state depending on the temperature of coolant. When it reaches a preset  temperature, the disc snaps, shutting off the circuit that activates the radiator cooling fan.

Coolant sensor has also become the "water temperature sensor" generally installed in the engine cylinder water jacket or coolant pipe, used to detect the temperature of the coolant, the internal water temperature sensor uses a negative temperature coefficient thermistor, the higher the temperature of the engine coolant the greater the resistance, the lower the temperature of the engine coolant the smaller the resistance, And to the electronic control unit to provide engine cooling water temperature signal.

The water temperature sensor can directly replace the faulty or damaged oil/water thermometer sensor on the market.

Universal 3/8 "NPT oil/water temperature sensor, temperature range from 0-150C / 0-300F. This is a two-wire sensor for signal to meter.

The boday of the water temperature sensor is made of high quality brass material, with good temperature conduction effect and high precision of temperature signal transmission.

The output end of the sensor is fastened by injection molding process, which can withstand high and low temperature and has stable performance.
