tachometer gauge with shift light

• 2022-03-11

The tachometer is to change the rotational speed of the object into the corresponding electric pulse series, and then use the moving coil pointer meter to show the rotational frequency (i.e. rotational speed) At this time, a large capacitor shall be connected to the meter for measuring the speed; If the pulse series generated by the tested object is about 1Hz (i.e. one revolution per second), the capacitor needs to reach 30000 μ F. In order to ensure the accuracy of measuring speed (generally refers to the linear scale of the meter)

There is a sensor for driving shaft speed on the engine . It will send pulse signals with the rotation of engine shaft. Some gasoline and will take point and pulse signals. This signal is transmitted to the computer equipment of the engine and input a control signal after calculation . Then send to the schedule . The driving of this watch is controlled by the stepping motor, and the pointer can be directly installed on the rotating hand shaft of the stepping machine. The faster the engine speed, the more pulses will be generated , and the greater the speed value displayed on the table. In order to accurately display the speed , the stepping motor takes one step only 1 / 3 of the degree .

The warning light is also called Double flashing , that is , the two turn signals flash together . The switch of double flashing is generally in the central control . There is a button with a red triangle icon . Press it to turn on / off the double flashing. At this time , the corresponding indicator light on the instrument panel will also flash. Turn signal lamp is another common lamp besides headlamp, but it is ignored by many people, so it also causes many traffic accidents . The steering lights are all on the paddle on the left side of the steering wheel (even if other switches are on the knob) , so that the driver can turn on and off the steering lights without leaving the steering wheel . Just as the steering wheel turns the direction , up is the right turn signal , down is the turn signal , and when the steering wheel returns to timing after steering, they will automatically bounce back to their original position .

Here we have a tachometer gauge with shift light . Please check the below photo . The gauge also has speedometer , odometer . Very cost-effective .
