2 inch water electric temp gauge pro comp

The 2 inch water electric water temp gauge pro comp on the vehicle dashboard is different, but the criteria for judging the water temperature are the same. Generally, the indication is in the middle position, about 90 ℃ is appropriate. The engine coolant temperature is not the lower the better, nor the higher the better. It needs to be within a certain range. The normal temperature is 90 ℃ at the center of the pointer.  After the vehicle is started, the antifreeze temperature rises rapidly. After the pointer reaches the central position, the antifreeze temperature in the heat exchange balance will not rise. Generally speaking, the best start is when the temperature reaches the middle position. The water temperature sensing plug is pressed on the engine body, and the 2 inch water electric water temp gauge pro comp shows the temperature of the circulating water in the engine.  The sensor of the water meter is a thermistor sensor. Screw on the engine cooling water channel. The thermistor determines the current flowing through the coil winding of the thermometer. This will drive the instrument pointer to swing. In the past, tap water was used as cooling water for automobile engines. Now many automobile engine cooling systems use special coolant. Therefore, it is also called coolant thermometer.

What about the 2 inch water electric water temp gauge pro comp ? The water temperature is from c to h, and c represents 60 degrees. As long as the pointer of the water temperature gauge reaches 1 to c, the water temperature has reached 60 degrees; H The temperature indicated by the red grid is 110 degrees. The pointer should always be kept in the middle position. When the pointer enters the red area, the water temperature is too high. If the water temperature is too high for a long time, there will be "boiling", that is, the engine coolant will boil, which will cause the water tank to expand and crack, and the engine will be overheated and damaged.

2 inch water electric temp gauge pro comp sensor is very important. When the power switch is turned on, the current is divided into two circuits by the battery positive power switch resistance r coil l2 (one circuit flows through the thermistor 1. the other circuit flows through the coil l1), which is grounded to the battery negative pole to form a circuit.
