Automotive voltmeter: designation, description

For sure, every person in his life encountered such an instrument as a voltmeter, and knows what is its main function. This is the determination of the voltage value of the electrical circuit. An analog voltmeter is a device with a pointer and a scale. Recently, digital voltmeters have gained special popularity, they are characterized by more accurate indications and compact dimensions. This article will deal with a special model of a measuring device, such as automotive Th voltmeter. It can be performed as a simple voltmeter and combined. The combined car voltmeter contains additional functions, such as a tachometer, a thermometer, etc. Let's consider in more detail such device.

The car voltmeter has small overall dimensions, so it can be installed anywhere in the car. Quite often such a device is combined with a plug of the cigarette lighter connector. If necessary, you can insert the device into the cigarette lighter and use it to track the charge of the battery in different modes of operation. So, the normal voltage of the battery with a "muffled" engine is 12.5 volts, and with a wound - 13.5-14.5 volts. If the voltage exceeds, or, conversely, below the norm, then it is required to check the electrical system of the car. The car voltmeter is simply indispensable for fans to listen to music, especially at a picnic or nature. It allows you to monitor the charge of the battery and not allow the discharge below normal. Many motorists know that to be guided by signals of regular car alarms Battery discharges are undesirable, since they usually signal when the battery, generator or relay generator goes out of order, and it's too late to take any measures. The car digital voltmeter allows you to notice changes in the electrical system of the car in time. There are options for connecting remote displays, so the driver will always see the readings of the device.

Now consider the combined devices. Automotive tachometer-voltmeter can be installed anywhere in the car interior, and if necessary under the hood. This device allows you to display not only the voltage of the on-board network , But also the temperature of the air in the car and on the street, as well as the temperature of the engine of the car, and, of course, the number of engine speed. Such devices can be used not only in cars, but also at home to indicate indoor and outdoor temperatures. In conjunction with the car tachometer-voltmeter temperature sensors are sold . In the thermometer mode, the sensors are able to measure the temperature in the specified range from -50 to +127 degrees Celsius. Connection of the specified sensor can be carried out independently, and it is possible to entrust the autoelectrics.

Here we have briefly considered what is an automobile voltmeter and a combined device. Knowledge of how to use these devices will be useful to every car owner.
