water temp oil pressure gauge
1. Oil pressure gauge;
The sensor of the oil pressure gauge is a piezoresistive sensor. Screw onto the oil pipe. The oil pressure pushes the contact piece to move on the resistance, thus changing the resistance value, thus affecting the amount of current flowing to the ground through the instrument. Drive the pointer to swing. Because the oil pressure has a certain pressure range, for the sake of clarity. At present, many automobile oil pressure gauges are indicated by indicator lights. If the engine is still running. This means that the engine lubrication system may be abnormal.
2. Water temperature gauge;
The sensor of the water meter is a thermistor sensor. Screw on engine cooling water channel. The thermistor determines the current flowing through the coil winding of the thermometer. This drives the pointer of the instrument to swing. In the past, tap water was used as cooling water for automobile engines. Many automotive engine cooling systems now use special coolant. Therefore, it is also called coolant thermometer.Because the design methods of each car manufacturer will be different, that is to say, there are various styles except the milestone speed meter, but no matter how the manufacturer sets it, the water source meter on the car will generally be marked with C and H2 in English. The letters are distinguished by white and red lines. C stands for cold and H stands for hot. If the water temperature is close to H, or in the red area, it means that the water temperature warning light is on. If the engine coolant is too high. It means that its water temperature division is in normal
If it is added water temp oil pressure gauge oil temp,its because monitoring data. The water temperature, oil temperature and oil pressure triple gauge is added to monitor data, so as to better pay attention to whether various data are normal. It is a must for performance enthusiasts to monitor the running state of the engine in real time, and use data to reflect whether the lubrication and cooling systems are normal under the current working conditions, so as to ensure that the driver can obtain danger signals in advance before the car goes wrong. The electronic water temperature and oil pressure gauge can display the engine cooling water temperature and oil pressure. The sensor boundary and W2 are of bimetallic sheet type. Water temperature sensor W, installed on the engine cooling water jacket, is connected in series with the resistance to form a water temperature measuring circuit;
