Oil pressure sensor switch 6306707 for Volvo D12 D16

The Points for Attention in the Use of Oil Pressure Sensor

1. Working principle of hydraulic sensor The pressure of the wind pressure sensor directly acts on the diaphragm of the sensor, causing the diaphragm to slightly displace in direct proportion to the pressure of the medium, so that the resistance of the sensor changes. This change is detected by electronic circuit, and a standard signal corresponding to this pressure is converted and output.

2. There is a similar float inside the oil pressure sensor, and there is a metal plate on the float and a metal plate inside the sensor housing. When the pressure is normal, the two metal plates are separated, and only when the pressure is insufficient, the two metal plates are combined and the alarm light is on. Therefore, the oil pressure sensor itself has no function of sensing temperature.

3. There is a sliding resistor in the oil pressure sensor. Use the oil pressure to push the potentiometer of the sliding resistor to move, change the current of the oil pressure gauge and change the orientation of the pointer.

When the engine temperature is high, sludge will easily occur, so it is necessary to pay attention to the maintenance of the engine and the selection of oil. It makes sense to choose high-quality engine oil. Why do high-quality engine oils, such as Shell, attach great importance to the cleanliness of products? It is precisely because the engine oil is related to the smoothness, wear reduction, temperature reduction and sealing of the engine, and the engine oil with poor cleanliness can often not prevent the accumulation of carbon deposits. The accumulation of carbon deposits in the engine will accelerate the wear of cylinder liners, pistons and piston rings, which will cause more serious harm to the engine.
