Strain gauges (resistive elements) in the silicon sensor are used in a Wheatstone Bridge circuit. When the media’s 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 piezoresistive pressure sensors are generally sensitive to changes in temperature, the MediaGauge™ MG-9V digital pressure gauge uses signal conditioning to compensate for temperature and calibration. The output Measurement Technology In general, pressure measurement technology translates a force from an induced pressure into an electrical quantity. In signal is then converted into one of 3 user selectable forms (select units with the ON/UNIT/OFF button): digital pressure gauges, the electrical quantity is then translated into pressure units and digitally displayed. The SSI’s MediaGauge™ MG-9V digital pressure gauge includes an 304L stainless steel input pressure port, a 1) PSI piezoresistive pressure sensing element, signal conditioning 2) BAR circuitry for temperature and calibration compensation, and a LCD that displays the pressure measured in either PSI, 3) MPA (kg/cm²) BAR or MPA (kg/cm²) units. The piezoresistive sensing element consists of an oil-filled micro-machined 316L stainless steel convoluted diaphragm and a silicon crystal sensor. The MediaGauge™ MG-9V digital pressure gauge will display the pressure reading after the ON/UNIT/OFF button is depressed. The pressure measurement reading is The silicon crystal sensor is mounted on a 304L stainless steel housing and laser welded to the diaphragm. Optimal media isolation is updated 3 times per second. achieved when the media’s pressure acts directly on the SSI TECHNOLOGIES, INC.

The MediaGauge™ MG-9V panel has a LCD display and three multi-functional buttons – ON/UNIT/OFF; Backlight/P-H (Peak-Held) and RESET/CLEAR. To turn the LCD backlight on: Press the Backlight/P-H button once. To turn the LCD backlight off: Press the button again. To see the maximum peak pressure the unit has measured: Press and hold down the Backlight/P-H button for 3 seconds. The maximum pressure reading will be blinking. If the maximum pressure read was over the unit’s maximum pressure range, o.L will be blinking on the display. Press the To return to the current pressure reading: Backlight/P-H button and hold down for 3 seconds. The RESET/CLEAR button is used to reset the gauge to whatever pressure is currently applied to the port and to clear the stored maximum peak pressure reading. The To reference your MediaGauge™ digital pressure gauge to the ON/UNIT/OFF button is used to display the input port: Press and hold the RESET/CLEAR button for 3 pressure reading; switch between pressure units (PSI; BAR; and MPA) and to power down the unit. seconds. The MediaGauge™ MG-9V will now be reference to your input port. For example, if you have 20 psi on the display and then you press and hold the RESET/CLEAR button for 3 seconds the display will show 0.0 psi. A To power on the unit: Press the ON/UNIT/OFF button. The MediaGauge™ MG-9V has a battery saver mode and will automatically shut off the display after 5 minutes. measurement of 30 psi would then read as 10 psi on the display. To display the pressure reading in a different pressure unit: To reset the MediaGauge™ digital pressure gauge: Make sure Continue to depress the ON/UNIT/OFF button until the arrow in the LCD points to the pressure units desired. the input port is either disconnected or connected to a 0 psi To manually power down the unit: Press the ON/UNIT/OFF input. Press and hold down the RESET/CLEAR button for 3 seconds. button and hold down for 3 seconds until OFF is displayed and then release the button. SSI TECHNOLOGIES, INC.
