Introduction to Various Sensors of Cummins Diesel Generator Set

by Dieselgenerator Tech ***

The sensor of diesel generator set is generally composed of three parts: sensing element, conversion element and conversion circuit. With the continuous progress of science and technology, the technical level of diesel generator set is also constantly improving. In particular, the precision of all kinds of sensors of sino-foreign joint venture brand diesel generator sets is getting higher and higher, and the requirements for the parameters of diesel generators are more and more strict. This paper will analyze the functions and detection of various sensors of Cummins diesel generator set for you.

1.Coolant (water) temperature sensor.

The Cummins diesel generator coolant (water) temperature sensor is a cylinder located on the front right that functions to control fan rotation, adjust the starting fuel supply, control injection timing and engine protection. General diesel generators operate in the range of -40-140℃. Coolant (water) temperature sensor failure will lead to a lower engine speed and power decline, startup difficulties, the generator will be shut down, if the diesel generator is designed to protect the function, then use the temperature sensor, thermal sensor two-wire, two-wire sensor power line and rear line with two wire provided. Thermistor is a resistance that decreases with increasing temperature. Therefore, we can use a multimeter to test the resistance value of the temperature sensor of the wire plug, and judge with the normal value, if the temperature sensor works normally or not. The temperature sensors listed here are within the normal range of parameters applicable to all other joint venture diesel generator series temperature sensors.

2.Fuel oil temperature sensor.

The sensor is mounted on top of the fuel filter inner housing. Its function is to control the fuel heater and protect the diesel generator through the sensor signal. Its working range is -40℃-140℃. The sensor is faulty, which affects the performance of the engine. It is maintained in the same way as the coolant temperature sensor.

3.Air pressure sensor.

The sensor is installed in the DIESEL generator ECM800. Its function is to enable the sensor signal to determine the current atmospheric pressure.

4.Speed sensor (crankshaft speed sensor).

The sensor is installed in the front gear housing of the diesel generator set and its function is to test the pulse of the psa and calculate the engine speed and control the oil supply. The failure of the speed sensor will lead to insufficient power of the diesel generator set, unstable idle speed, white smoke emission, and difficult to start or close the unit.
