Tire pressure gauges come in countless shapes and sizes, but they all boil down to several basic types. Dial, numbers,. It may look different meters and display different results, but they all use the same.
The first and most common measure is the stick type, also known as the pen type. It consists of a metal or plastic shell, a pocket clip and a deep sleeve chuck, which is usually used on the other side for pressure relief bumps.
The second type of pressure gauge is the dial type. It contains a protective cover around the background pressure scale dial indicator on the same dial. An air chuck or a piece of hose is connected to the dial. These meters are easier to read, but more expensive.
The third type is the digital tire pressure gauge. It consists of some necessary electronic products around a protective casing, in the form of digital readings read by the driver. An air clamp is connected to a rigid or section of hose sleeve. These meters are the easiest to use, they have a direct LCD reading, and some even talk! The electronic components used in these meters are called strain gauges. The air from the tire enters the pressure gauge in the body and it pushes the strain gauge. The resulting bending strain gauge changes its resistance value. This resistance change is input to the microprocessor and converted into a binary signal for driving LCD readings. In all shapes and sizes, these meters are very accurate and very durable.
