Measurement Technology
In general, pressure measurement technology translates
force from an induced pressure into an electrical quantity.
The MediaSensor™ family of pressure transducers and
transmitters use piezoresistive technology for its sensor
signal processing to measure pressure.
A micro-machined stainless steel convoluted diaphragm
with a silicon crystal semiconductor is used. Strain gauges
(resistive elements) in the silicon crystal are used in a
Wheatstone Bridge circuit. When pressure is applied, the
resistivity of the strain gauges changes proportional to the
pressure applied. Since a single silicon crystal is used it
has a low mechanical hysteresis with good linearity.
One leg of the bridge measures the input pressures port.
The other leg of the bridge is connected to the reference
port the input pressure port is compared to. The connection
to this reference port determines the pressure sensing
convention used.
The MediaSensor™ family comes in a choice of three
pressure sensing type conventions: absolute, gauge
(vented or sealed).

Absolute MediaSensors™ measure pressure relative to
perfect Vacuum pressure (0 PSI) which remains unchanged
regardless of temperature, location or other ambient
conditions such as weather. Absolute MediaSensors™ are
calibrated to have 0.5 Vdc, 1 Vdc, or 4 mA respectively at 0
PSIA.
There are two different gauge pressure conventions –
Vented Gauge and Sealed Gauge. Gauge MediaSensors™
measure pressure relative to ambient room pressure
through a port that is vented (open) to the atmosphere.
Gauge MediaSensors™ are calibrated to have 0.5 Vdc, 1
Vdc, or 4 mA respectively at 0 PSIG.
Sealed MediaSensors™ measure pressure relative to a port
that is connected to a sealed perfect vacuum chamber.
Sealed MediaSensors™ are calibrated to 14.5 PSI
absolute. Sealed MediaSensors™ are calibrated to have
0.5Vdc, 1 Vdc, or 4 mA respectively at 14.5 PSIA.
The MediaSensor™ takes the two voltage output ports of
the
Piezoresistive pressure sensors are sensitive to changes in
temperature. The MediaSensor™ uses signal conditioning
to compensate for temperature and calibration. The output
signal is then converted into one of four forms:
1) 0.5 – 4.5 Volt ratiometric output (transducer)
2) 0.5 – 4.5 V ratiometric output with Overvoltage
3) 1 – 5 volt output (transducer)
4) 4 – 20 mA output (transmitters)
