speedometer and tachometer combo price
The tachometer refers to the measurement of engine speed, and the speedometer refers to the display of the vehicle's instant speed. Tachometer is one of the necessary instruments in the machinery industry, which is used to measure the rotational speed, linear speed or frequency of the motor. The speedometer is used to view the driving speed. It supports two units of miles hour or kilometers hour. The following is the difference between the automobile tachometer and the speedometer: 1. The speedometer reflects how many miles the vehicle runs per hour, and the tachometer reflects how many revolutions the engine turns per minute; 2. The speedometer refers to the driving speed of the vehicle in the general range of 0-300KM /h; 3. The tachometer refers to the engine speed which is generally 0-8000r/min.
Many people think of the speedometer for the instrument of the car. The speedometer can show us your speed in real time, and the driver can also adjust the driving state of the car according to the speed. However, there is usually a watch next to the speedometer, which also occupies half of the sky of the dial. That is the car's tachometer. Many people know that cars have speedometers and tachometers when they learn to drive. Especially in the second subject, many people are looking at the tachometer to do the uphill. Keep the number of revolutions at 1500, slowly lift the clutch on the slope, and start steadily. The tachometer can not only monitor the number of revolutions of the engine, but also reflect some faults related to the engine transmission of the car. For example, your car's clutch is slipping, which can be seen from the tachometer. For example, if there is a problem with your gearbox, the tachometer can also show it.
For automatic transmission vehicles, many drivers will not look at the tachometer. Because they can go just by stepping on the accelerator, and the tachometer is useless. However, the automatic transmission model can also reflect the running state of the car through the tachometer, so it is still useful. Moreover, many automobile enterprises have both manual and automatic gears for the same type of vehicle. It is normal to use the same instrument. For electric vehicles, the tachometer is basically useless, because the torque range of the electric vehicle motor is larger than that of the engine, so it is unnecessary to monitor the engine revolution. This is why some electric vehicles do not have a tachometer. Normal cars need tachometers and speedometers, so they can be used in combination.
