How Does A Tire Pressure Gauge Work

Pin inside the gauge presses against the valve pin inside the valve.

How does a tire pressure gauge work. When the pressure drops to a pre set level the sensor alerts the cars ecu commonly via rf transmission and this flags up a warning on the dashboard. Conventional tire pressure gauges are about the size of a pencil. Tire pressure gauges are designed to take a maximum psi of air. As air rushes out of the tire it forces the plastic rod to extend.

The pressure gauge can only measure up to a specified maximum. Stem and releasing air from the tire into the gauge. The only exception is an absolute pressure reading gauge and im willing to bet money marbles or chalk that no one out there has a tire pressure gauge that reads absolute pressure. A tire pressure gauge is a relatively simple device.

When this happens the air pressure applied on the piston of the gauge determines it to move in such a way that the volume of the cylinder increases. Its got a funny little spherical thing on one end and a little sliding scale on the other end. Use the tire gauge to measure the amount of air you are letting out. Stem to release air from the tire.

As the pressure gauge is coupled to the valve stem of the tire pressurized air enters the piston and starts to expand. With a pressure gauge. You can also use the tire pressure gauge to push the rod down and let air out. Use the tip end of the valve cap to let air out of the tire by pushing down the little rod inside the tire valve.

For example if the maximum is 50 psi then half way down the chamber is 25 psi and so on.

To measure the pressure of a tire place the gauge on the valve stem of the tire pressing the pin to let pressurized air rush into the gauge. If youve got a car you probably own one of those pen sized tire pressure gauges. There are two main types of tyre pressure monitoring systems tpms direct and indirect. Tire pressure gauges how they work.

They typically have metal exteriors with plastic rods that extend when the device is attached to a tire stem. Unscrew the valve cap on the tire. A piston inside the gauge travels a distance that matches the air pressure. How to use a conventional tire pressure gauge.

Get in a steady position to apply the pressure gauge to the valve. Apply the gauge forming a good seal between the gauge and the.
