Part Number: 701/54400
Component Type: Temperature sensor (thermistor)
Application: Engine cooling system / transmission system
Manufacturer: Aftermarket
The temperature sensor is a key component of the JCB machine monitoring system. It is a thermistor — a resistor whose resistance changes with the temperature of the medium. Depending on the machine configuration, the sensor is screwed into the engine block (water jacket) or into the transmission housing, where it monitors the temperature of the transmission oil.
The sensor sends an electrical signal to the dashboard gauge or to the ECU control module, informing the operator when the operating temperature has been reached or when overheating occurs. In this way, it protects the engine and transmission from costly damage.
Application:
A universal sensor used in many JCB machines, including:
JCB crawler excavators
machines with engine temperature monitoring
FITS: JCB
MACHINE MODELS: JS200, JS180, JS450LC, JS330, JZ255, JS460
OEM NUMBERS: 701/54400
