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™ MG1-9V digital pressure gauge
includes an 316L 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
with a silicon crystal sensor. The silicon crystal sensor is
mounted on a 304L stainless steel housing and laser
welded to the diaphragm.
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.
