Oil pressure gauge
Commonly known as the oil gauge, it indicates the lubricating oil pressure of the main oil passage of the lubricating system when the engine is running. As for the amount of oil in the oil pan, it needs to be measured by the oil dipstick next to the engine. Nowadays, most cars use warning lights instead of oil pressure gauges.Oil pressure gauge, oil pressure sensor, power supply, ignition switch, fuse.Oil pressure sensor: generally installed on the main oil passage or oil pump.Composition of oil pressure gauge when the engine is working, the oil pressure gauge indicates the oil pressure in the main oil passage of the engine lubrication system. It is composed of oil pressure indicator and oil pressure sensor.
When the engine is working, the oil pressure gauge indicates the oil pressure in the main oil passage of the engine lubrication system. It is composed of oil pressure indicator and oil pressure sensor. The oil pressure indicator is installed on the instrument panel, and the oil pressure sensor is installed on the engine main oil passage or oil primary filter, which are connected through wires. Common oil pressure gauges include bimetallic oil pressure gauge and bimetallic oil pressure sensor, electromagnetic oil pressure gauge and resistive oil pressure sensor. Bimetallic oil pressure gauge is widely used.
Oil pressure alarm device:
Some vehicles equipped with oil pressure gauge are also equipped with oil pressure alarm lamp. When the oil pressure is lower than the normal value, the alarm lamp will turn on and send an alarm signal to the driver. The utility model is composed of an oil low pressure alarm lamp installed on the instrument panel and an oil pressure alarm sensor installed on the main oil passage of the engine.
Oil pressure indication system:
There is no oil pressure gauge on the instrument panel of some models. The oil pressure indication system is used to monitor the oil pressure of the lubrication system. When the oil pressure is too low or too high, it will alarm through the oil pressure alarm lamp and buzzer.Some vehicles adopt the integrated electronic indication and alarm system of oil pressure and water temperature, which is composed of four LM339 chips and test and display circuits.
