A digital pressure gauge uses electronic sensors and a digital display to measure and present pressure readings. It differs from a traditional pressure gauge, which uses dials and needles.

Digital pressure gauges work by converting the applied pressure into an electronic signal that is then displayed numerically on a digital display. Digital pressure gauges use a sensor/transducer to convert the pressure value into an electronic signal that is then translated into a digital reading.

It is recommended at least once every twelve months. Calibration may be required more frequently, subject to the gauge operation time, pressure medium, environmental factors, as well as standard operating conditions and general maintenance.

Digital pressure gauges convert the pressure value into a signal through the use of a sensor/transducer and displays the correlated reading on a digital display. Analogue pressure gauges use a mechanical component, such as a bourdon tube, to sense pressure. The bourdon tube is linked to a circular scale dial and needle that rotates mechanically with the pressure.

Digital pressure gauges are more accurate than analogue pressure gauges due to being engineered with modern technology. Digital pressure gauges are electronic and only rely on the pressure being converted to an electronic signal in order to be measured. Due to their limited reliance on mechanical parts, digital pressure gauges are less at risk of wear and tear, better maintaining their accuracy over time.

A digital pressure gauge is able to offer a more accurate reading than an analogue gauge.

The frequency at which a digital pressure gauge needs to be calibrated depends on the level of accuracy required. Some companies re-certify/recalibrate their gauges every 6 months, however, every 12 months is the industry standard.

You should maintain it by keeping it clean, avoiding over-pressure spikes and excessive shock and following the manufacturer's recommendations.
