SSI Technologies – Application Note PS-AN6 MediaGauge™ (Model MG1-9V) Digital Pressure Gauge Product Overview Product Description The MediaGauge™ Model MG1-9V is a NEMA 4X rated stand alone 9V battery operated multi-functional digital pressure gauge with a standard input pressure port made of 316L stainless steel which has better pitting corrosion resistance in some media, such as seawater. The MediaGauge™ MG1-9V is well suited for marine applications. The MediaGauge™ MG1-9V contains a media isolated piezoresistive pressure sensing element, signal conditioning circuitry for temperature and calibration compensation, a pressure port and a LCD back lit display. The MG1-9V has an accuracy of ± 1.0% full scale and is a lower cost alternative in the SSI MediaGauge™ family of digital pressure gauges. The MediaGauge™ MG1-9V comes 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 MediaGauge™ MG1-9V is made of all laser-welded 316L stainless steel for optimal media isolation and usage in a wide MediaGauge™ Model MG1-9V variety of media and corrosion or oxidation resistant applications. These compact 2 ½ inch, robust gauges measure pressures from Product Features 5 PSI to 5000 PSI and are well suited for a variety of industrial and commercial applications such as marine, ▪ Accuracy: ± 1.0 % Full Scale refrigeration, compressors, pumps, hydraulics, pneumatics and waste water. ▪ Pressure Ranges: 5, 30, 100, 200, 500, 1000, 3000, 5000 PSI The MediaGauge™ MG1-9V digital pressure gauge has better accuracy, longer life and standard multiple functions which make it a better choice than mechanical pressure gauges. ▪ Keypad Operated Functions: Auto zero and peak hold ▪ Operating Temperature: -10°C to 60°C SSI TECHNOLOGIES, INC.

For example, Sea Water, Salt Water, Motor Oil, Diesel, Hydraulic fluid, Brake Fluid, Water, Waste Water, Hydrogen, Nitrogen, and Air. a LCD that displays the pressure measured in either PSI, BAR or MPA (kg/cm²) units. The piezoresistive sensing element consists of an oil filled micro-machined 316L stainless steel convoluted diaphragm with a silicon crystal sensor. The silicon crystal sensor is LCD Display Battery Saver Mode: MG1-9V automatically powers down after 3 minutes. ▪ Multiple Pressure Units: PSI, BAR, MPA (kg/cm²) ▪ Compact, Robust Package: 2 ½ inches with black ABS Thermoplastic case mounted on a 304L stainless steel housing and laser welded to the diaphragm. Optimal media isolation is achieved when the media’s pressure acts directly on the 316L stainless steel diaphragm and is then transferred through the oil to the silicon sensor. Strain gauges (resistive elements) in the silicon are used in a Wheatstone Bridge circuit. When pressure is applied, the resistivity of the strain gauges changes proportional to the pressure applied. One leg of the bridge measures the input pressures port. The other leg of the bridge is connected to the reference port (vacuum pressure 0 PSI) the input pressure port is compared to.

Since piezo resistive pressure sensors are sensitive to To manually power down the unit: Press the ON/UNIT/OFF changes in temperature, the MediaGauge™ MG1-9V uses signal conditioning to compensate for temperature and calibration. The output signal is then converted into one of 3 user selectable forms (select units with the ON/UNIT/OFF button): button and hold down for 3 seconds until OFF is displayed and then release the button. The LIGHT/P-H (Peak-Hold) button is used to turn the LCD backlight on/off and to display the maximum peak pressure the 1) PSI unit has measured. 2) BAR 3) MPA (kg/cm²) To turn the LCD backlight on: Press the LIGHT/P-H button once.
