The role of a pressure gauge on a car compressor, how to change and repair a pressure gauge on a car compressor, the best models of pressure gauges

When the device shows incorrect data or does not work, then it must be changed or attempted to be repaired. If you can’t fix the pressure gauge on the car compressor, then there is only one way out - replacement.
A car compressor pressure gauge is used to measure tire pressure. Based on his testimony, the driver decides whether to inflate the wheels.
The value of the pressure gauge in the autocompressor
The absence of a pressure gauge on a car compressor does not affect it in any way: some drivers inflate tires without a measuring device, by eye. But incorrect pressure negatively affects the performance of the machine.
At high levels, the following negative effects are observed:
- The damping capabilities of the vehicle are reduced. Vibrations that occur when hitting pits or bumps are transmitted to all vehicle components. This leads to a decrease in comfort for passengers and the driver, and can also cause breakdowns. The suspension is especially hard hit.
- High pressure increases the load on the tire and stretches it. Therefore, even good rubber can break when a vehicle hits a pit or hits a hillock.
- An overinflated wheel reduces the contact patch with the road, which adversely affects the vehicle's handling.
The value of the pressure gauge in the autocompressor
Low blood pressure is dangerous in the following ways:
- The tire does not hold well on the disk, which is why during a sharp maneuver there is a risk of disassembly. This can lead to severe damage and even an accident.
- Low tire pressure increases the contact patch, which increases rolling friction and rolling resistance. This increases fuel consumption by 3-5% per month. Also, with a large contact patch when driving through puddles, the wheels begin to slip, the vehicle loses controllability.
- If the pressure is constantly below normal, then the heating of the tires and the increased load on the side parts will reduce the life of the tires.
The device and the principle of operation
All pressure gauges for a car compressor are divided into two types: mechanical and digital.
The first are reliable and low price. But they are sensitive to moisture, and reading data from them is not as convenient as from digital ones. According to the principle of operation, analog devices are spring and diaphragm, or membrane.
Spring loaded
The main sensitive element of this type of pressure gauges for automobile compressors is the Bourdon tube (2). It is hollow, made of brass and bent in an arc. One end is soldered, and the other is connected through a fitting to the area in which you want to measure. With increasing pressure, the tube will tend to straighten out due to the existing difference in the areas affected by the air.
The device and the principle of operation
As a result, the soldered end is displaced and acts on the gear train through the rod (5), and the pointer of the device moves.
Diaphragm
In such a pressure gauge for an automobile compressor, the compressed air whose pressure is to be measured acts on the membrane (4). It bends and through the mechanism of thrust (3) moves the arrow (2).
The measuring range depends on the characteristics of the membrane, such as stiffness and area.
digital
Digital pressure gauges for autocompressor are superior to mechanical ones in terms of accuracy and ease of use. However, they cannot be used in the cold, they are more expensive than analog ones. The sensitive element of digital devices is a piezoelectric sensor that generates electricity under mechanical action.
How to change the pressure gauge: instructions
When the device shows incorrect data or does not work, then it must be changed or attempted to be repaired. If you can’t fix the pressure gauge on the car compressor, then there is only one way out - replacement.
First you need to buy the right model. To complete the work, only a key is required from the tools.
How to change the pressure gauge
You need to act as follows:
- Disconnect the compressor from the mains.
- Bleed the air.
- Unscrew the old device.
- Clean thread.
- Apply fresh sealant to the new device.
- Install the pressure gauge for the car compressor in place.
This completes the work.
