Temperature Sensor of Engine Cylinder Head
Working Principle of Temperature Sensor of Engine Cylinder Head
The engine cylinder head temperature sensor is
used in the air cooled engine to me
asure the
temperature of engine cylinder head. Within the sensor
temperature range, the resistance will change with the
temperature of engine and the temperature
characteristic is the negative temperature coefficient
resistance characteristic. It is an irreparable part.

Right figure
Working Environment
 The sensor is mainly used for water-cooled engine
 Normal operating temperature range: -40 -160°C
(continuous work)
 Working environment relative humidity: 0 ~ 100%

Typical operating pressure: at minimum
installation torque, the sensor is capable of sealing
the engine coolant at an actual pressure of 206.8
kPa (30 psi) and a temperature of 135°C.

Extreme working conditions: only 1 hour at
maximum temperature of 160°C.
Electrical environment

Typical operating voltage: the reference voltage is
5 ± 0.1VDC

Maximum excitation current: During the
characteristic test and calibration of the sensor
under any temperature, the performance of the
sensor should not be affected by the current of less
