The MediaGague MG-MD is a multi-functional digital pressure gauge consisting of a media isolated piezoresistive pressure sensing element, signal conditioning circuitry for temperature and calibration compensation, a 304L stainless steel pressure port and a LCD back lit display. The MG-MD digital pressure gauge has an accuracy of +- .25% full scale for 75 to 3000 psi. The MediaGauge MG-MD digital pressure gauge is powered by an external 8 - 30 Vdc external power supply and comes standard with a wide variety of functions - multiple pressure unit display readings (PSI, BAR or MPA units); memory storage of maximum peak pressure reading; zero adjustment; a 4-20 mA current output along with a limit switch (NPN transistor) to interface to monitoring and control systems. The Media Gauge MG-MD is made of all laser-welded 304L & 316L stainless steel for optimal media isolation and usage in a wide variety of media. These compact 3 inch robust digital pressure gauges measure pressures from 5 PSI to 5000 PSI and are ideal for a variety of industrial and commercial applications such as process control, refrigeration, compressors, pumps, hydraulics, pneumatics and waste water. The MediaGauge MG-MD digital pressure gauge has better accuracy, longer life and standard multiple functions which make it better choice than mechanical pressure gauges.
