MediaGauge™ (Model MG-9V) Digital Pressure Gauge
Product Overview
Product Description
The MediaGauge™ Model MG-9V digital pressure gauge is
a stand alone 9V battery operated multi-functional digital
pressure gauge. The MG-9V digital pressure gauge
contains a media isolated piezoresistive pressure sensing
element, signal conditioning circuitry for temperature and
calibration compensation, a 304L stainless steel input
pressure port and a LCD back lit display. The MG-9V digital
pressure gauge has an accuracy of ± 0.25 % full scale. A
battery power saver mode is incorporated into the MG-9V to
automatically shut the LCD display off after 5 minutes
prolonging the battery’s life.
The MediaGauge™ MG-9V digital pressure gauge 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

example, Motor Oil, Diesel, Hydraulic fluid, Brake Fluid,
Water, Waste Water, Hydrogen, Nitrogen, and Air.
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
signal is then converted into one of 3 user selectable forms
(select units with the ON/UNIT/OFF button):
Measurement Technology
In general, pressure measurement technology translates a
force from an induced pressure into an electrical quantity. In
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
piezoresistive pressure sensing element, signal conditioning
circuitry for temperature and calibration compensation, and
a LCD that displays the pressure measured in either PSI,
BAR or MPA (kg/cm²) units.

2) BAR
3) MPA (kg/cm²)
The piezoresistive sensing element consists of an oil-filled
micro-machined 316L stainless steel convoluted diaphragm
and a silicon crystal sensor. The silicon crystal sensor is
mounted on a 304L stainless steel housing and laser

MediaGauge™ (Model MG-9V) Digital Pressure Gauge
Product Overview
MediaGauge™ MG-9V Panel Operation
The Backlight/P-H (Peak-Held) button is used to turn
the LCD backlight on/off and to display the maximum peak
pressure the unit has measured.
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.
To return to the current pressure reading:
Press the
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.
To reference your MediaGauge™ digital pressure gauge to the
input port: Press and hold the RESET/CLEAR button for 3
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
The ON/UNIT/OFF button is used to display the
pressure reading; switch between pressure units (PSI; BAR;
and MPA) and to power down the unit.
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.
button for 3 seconds the display will show 0.0 psi.
A
measurement of 30 psi would then read as 10 psi on the
display.
To display the pressure reading in a different pressure unit:
Continue to depress the ON/UNIT/OFF button until the
arrow in the LCD points to the pressure units desired.
To reset the MediaGauge™ digital pressure gauge: Make sure
the input port is either disconnected or connected to a 0 psi
input. Press and hold down the RESET/CLEAR button for 3
seconds.
To manually power down the unit: Press the ON/UNIT/OFF
button and hold down for 3 seconds until OFF is displayed
and then release the button.
