Pressure gauges are used in manufacturing industries and other sectors to perform varied tasks; from menial tasks like inflating a car tyre to complex tasks. These gauges are frequently used but often overlooked, so they need to get calibrated frequently as the use of faulty equipment is risky. Before going on to its benefits, we should understand what pressure gauge calibration is. Let's look at the importance and value of pressure gauge calibration. Pressure gauge calibration methods are like pneumatic, hydraulic, and pressure deadweight testers. In the process you choose, make sure you hire an experienced professional. A test pump applies pressure to a gas or liquid through the port inputs found on both sides of the pump. Pressure is applied to the pressure gauge and the digital reference gauge, and readings are compared to understand discrepancies, a process is known as calibration through comparison. Many factors are considered, like buoyancy, gravity, and revolutions per second. This process is applied to pressure gauges when higher accuracy is required. After the test, a calibration certificate is given with a record of the calibration result including error limits, and calibration intervals, which help understand the instrument’s condition. No matter what calibration process is used if any discrepancy is more than the tolerance, the pressure gauge requires adjustment and calibration. https://zenithinstruments.com.au/pages/pressure-gauge-calibration
