SSI Technologies – Application Note PS-AN3 MediaGauge™ Digital Pressure Gauges Product Overview

Product Description

The MediaGauge™ digital pressure gauges have better accuracy, longer life and standard multiple functions which make it a better choice than mechanical pressure gauges. The MediaGauge™ family of digital pressure gauges has four models. The MediaGauge™ models differ in accuracy, pressure ranges, media isolation, supply voltage, user functions and output capabilities.All MediaGauge™ digital pressure gauges contain a piezoresistive pressure sensing element, signal conditioning circuitry for temperature and calibration compensation, a stainless steel input pressure port and a LCD back lit display. The MediaGauge™ digital pressures gauges, are made of all laser-welded 304L stainless steel and have a 316L stainless steel convoluted diaphragm (excluding the MGA-9V model) to optimize media isolation. The MGA-9V model is a lower cost digital pressure gauge with no diaphragm for use with dry air and non-corrosive gases. Three models (MG-9V; MGA-9V and MG1-9V) are stand alone 9V battery operated with a 4 digit display. The MG-MD model is powered by an 8 - 30 Vdc external power supply and has multiple outputs: a 4 digit display; a 4-20 mA current output and a user programmable set limit switch.

MediaGauge™ Family of Digital Pressure Gauges

The MG-MD is an excellent choice for process control applications where continuous monitoring and/or where a pressure set point limit switch is needed. All MediaGauge™ digital pressure gauges come standard with a variety of keypad operated functions – multiple pressure unit display reading (PSI, BAR or MPA); memory storage of maximum peak pressure reading; and zero adjustment. The MG-MD model also has user programmable high and low pressure set points. A Ft of Head pressure measurement display is available as an option on the MG-9V model.
