Measurement Technology
In general, pressure measurement technology translates a
force from an induced pressure into an electrical quantity. In
digital pressure gages, the electrical quantity is then
translated into pressure units and digitally displayed.
The SSI’s MediaGauge™ MGA-9V digital pressure gage
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.
The piezoresistive sensing element contains a silicon
crystal semiconductor. Strain gages (resistive elements) in
the silicon are used in a Wheatstone Bridge circuit. When
pressure is applied, the resistivity of the strain gages
changes proportional to the pressure applied. One leg of
the bridge measures the input pressures port.
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 sensitive to
changes in temperature, the MediaGauge™ 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):

The MediaGauge™ MGA-9V will display the pressure
reading after the ON/UNIT/OFF button is depressed. The
pressure measurement reading is updated 3 times per
second.
MediaGauge™ MGA-9V Panel
The MediaGauge™ MGA-9V panel has a LCD display and
three multi-functional buttons – ON/UNIT/OFF; LIGHT/P-H
(Peak-Held) and RESET/CLEAR.
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™ MGA-9V has a battery saver mode and will
automatically shut itself off after 5 minutes.
To display the pressure reading in a different pressure unit:
Continue to press the ON/UNIT/OFF button until the arrow
in the LCD points to the pressure units desired.
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.
The
LCD LIGHT on/off and to display the maximum peak
pressure the unit has measured.
To turn the LCD LIGHT on: Press the LIGHT/P-H button
once.
To turn the LCD LIGHT off:
again.
