A digital tire pressure gauge is a device that transforms applied pressure into signals. The readouts are displayed numerically.
You can find pretty various types of pressure-gauges technologies. Some use mechanical deflection and include an elastic or flexible element (diaphragm) that reacts to changes in pressure.
Digital pressure gauges may also include a bridge circuit and a diaphragm, but identify changes in capacitance. Strain gauges or strain-sensitive variable resistors are used as parts in Wheatstone bridge circuits that measure. Some digital pressure gauges use pistons, vibrating elements, MEMS (microelectromechanical systems) or thin film to sense changes in pressure.
Why use a digital tire pressure gauge?
You need to have your car tires inflated as this relates directly to your safety. Under-inflated tires build up excess heat when you drive and this may cause a tire failure. Not having enough tire pressure makes a tire wear out faster and unevenly, causes fuel wastes, and the vehicle starts to perform poorly on braking or handling.
You should check your tires pressure at least once a month, especially before a long trip. For accurate results, your car should be parked for at least three hours or more.
You may keep a tire-pressure gauge in a protective sleeve as the more it stays clean, the longer you’ll have it around, in a great state. No digital pressure gauge is reliable if it has been dropped or if it’s old, worn or dirty. So having a new one, in a good state, is a good investment for your safety.
Digital tire pressure gauges feature an electronic LCD display which makes them easy to read. They are resistant to damage from dirt and dust. Some digital tire pressure readouts light up, which makes them great for low-light conditions.
Best rated digital pressure gauges give no parallax error, have a back-lit capacity and give a steady reading in high vibration. They are also easy to re-range.
On the other hand, the digital tire pressure gauges are not able to read oscillating values and are not easy to see full scale or trending. On a plus, digital gauges are a bit bulkier than stick gauges and they to need batteries which need to be changed any now and then.
What to look for in a digital tire pressure gauge?
You need to check a few things when you select a digital tire pressure gauge. Devices differ when we talk about allowable pressure, accuracy, vacuum range or operating temperature.
The most important thing on a digital tire pressure gauge is its accuracy, meaning the difference between the true value and the indication expressed as percent of the span, often given by a lettered grade.
Digital tire pressure gauges may vary also when it comes to their features, as some include temperature outputs, temperature compensation, alarm switches or output switches that are compatible with transistor-transistor logic.
Any digital pressure gauge may produce several types of electrical signals, including analog voltage and analog current. Serial and parallel interfaces are also a thing to look for.
Tips on using digital pressure gauges
You only need a few minutes to check your tire pressures, as long as you use a well-maintained tire-pressure gauge. It’s very important to know the recommended pressure setting for your car (marked down on a plate or in your owner’s manual). Keep in mind that front and rear-tire pressure may differ.
Always check the pressure when the tires are cold and first remove the screw-off cap from each tire’s inflation valve. Pay attention to not lose the caps.
Insert the end of the tire-pressure gauge into the valve and depress it, look at the pressure reading.
Last, but not least, check the pressure of the spare tire also.
