4 in 1 tachometer gauges

• 2022-07-12

We have 4 in 1 tachometer gauges. It is cost effective and space saving. It includes the digital tachometer gauge , oil pressure gauge , water temp gauge and voltmeter gauge.

The most prominent feature of modern combined instruments is the modularization of functions. Usually, an instrument needs to be assembled. A complete system can be obtained by combining several functional modules on the basis of customized PCB. At present, the instruments are mainly pointer instruments, and each meter head is an independent module. The prompt and alarm indicators are realized by bulbs or light-emitting diodes on the PCB.

The instrument is an interactive interface between human and vehicle, which provides the driver with the required vehicle operating parameters, faults, mileage and other information. It is an essential component of every vehicle.

The most prominent feature of modern instruments is the modularization of functions. Usually, an instrument is assembled. A complete system can be obtained by combining several functional modules on the basis of customized PCB. The pointer instruments of economic vehicles such as Chang'an are generally independent modules. The indication / alarm function is completed by a small bulb on the PCB. The pointer of Santana series is driven by a cross coil on the printed circuit board, The prompt / alarm lights are all the main data, sources and corresponding display modes displayed on the instrument panel of the LED car.

It can be seen that automotive instruments are mainly mechanical and the communication mode is mainly wire harness. The biggest drawback of this mode is that it relies too much on wire harness, resulting in complex systems. With the rapid development of the automotive industry, the automotive electronics market with great potential is increasingly attracting the attention of major automotive manufacturers and electronic product suppliers, including clean energy vehicles that are still in the development and experimental stage. The on-board computer information terminal equipment of on-board audio equipment, which is dominated by Japan in the world market, as well as various in-vehicle electronic control units, such as engine electronic control unit, ABS, bus, new electronic instruments, etc. for automotive instruments, the advantage of using electronic instrument panel over traditional instruments lies in the software of hardware functions.

This four in one automobile instrument can provide the speed, oil pressure, water temperature and voltage to the owner, so that the owner can know the condition of the vehicle in time.
