52mm water temp gauge

Our company have 52mm water temp gauge , include needle type and digital type.

Generally speaking, the machine water temperature hand adopts physical or virtual dial pointer display, while a many vehicles have no instrument panel, and the warning sign appears only when the temperature is too high. The pointer exposure of both physical and virtual water temperature measures is principally analogous, which is generally marked with 60 ℃-120 ℃ dial or deep freeze (c)-hot (H). Antifreeze is different from traditional valve water. It can work at a temperature above 100 ℃ due to the addition of calcium chloride, methanol, ethanol, ethylene glycol, glycerol and other factors in organic matter.

From the above introduction, we know that 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 ℃ in the center of the pointer. After the vehicle starts, the antifreeze temperature rises rapidly. After the pointer reaches the central position, the heat exchange balance antifreeze temperature will not rise. Generally speaking, it is best to start when the temperature reaches the middle position, which is one of the reasons why the vehicle needs to be hot before starting.

When checking water temp gauge, remove the wiring and check the resistance between the input outstation of the detector and thegrounding.However, it indicates that it is good; Another 80-100 ohm resistance is used to replace the detector for direct grounding, If thermistor is about 100 ohms at room tempe. When the power is connected, if the needle of the water temindex is between 60 ℃ and 70 ℃, it indicates that the water tem index is in good condition.
