Digital Pressure Gauges
Unlike analog, or dial, pressure gauges, digital gauges are built for reliability in demanding conditions. Dial gauges require constant re-calibration and repair. One major dial gauge manufacturer estimates that in a typical plant, 25% of dial gauges need immediate replacement, and another 40% need corrective action. It’s a mess caused by inadequacies inherent in analog gauges
Our pressure transmitters, also known as pressure transducers, use piezoresistive technology to accurately measure pressure. This is based off of a small circuit called a Wheatstone bridge attached to the back of a diaphragm. As the diaphragm flexes from pressure, the resistance in the Wheatstone bridge (hereafter known as the “sensing element”) changes relative to pressure, providing a basis of measurement
