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.
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
welded to the diaphragm.

through the oil to the silicon sensor.
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.

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
