Sensors are very important for diesel generator set to monitor data by control panel. If incorrect use and selection, the diesel generator set may cause faults. Today Starlight Power will introduce the sensors of diesel generators. Hope the article is helpful to you. What is main sensor in a diesel generator? 1.Oil pressure sensor. Its function is mainly to monitor oil pressure, then we can know the capacity of oil. If the lubricating oil is less, the wear of the generator set will increase, resulting in the reduction of the service life of the diesel generator set. 2.Coolant temperature sensor. Its function is mainly to monitor coolant temperature , so that we can know whether the temperature of the water tank exceeds the normal value. Normal value is generally 85℃. If the temperature of the water tank is too high, the cylinder block will be heated too high, which will damage the diesel generator set and cause power failure. 3.Speed sensor. Its function is mainly to monitor whethe
