8-97217444-1 Water Temperature Sensor for Hitachi Zaxis330 Sh200A3 6HK1 Zx300 Excavator Parts
The display of water temperature of the excavator instrument is realized by using the voltage signal fed back by the analog water temperature sensor through the controller processing, the water temperature sensor is a negative temperature coefficient resistance, and its resistance value changes with the change of the engine water temperature, and the controller will transmit a signal voltage to the water temperature sensor. While the resistance value changes, the voltage as a feedback signal also changes, but when other circuits in the vehicle circuit system are turned on, it will also have a certain impact on the feedback signal of water temperature to a certain extent.
