etra System’s Model 522 General Purpose
pressure transducer is designed for OEM
industrial applications that require
exceptional stability and high accuracy.
The Model 522’s CVD strain gauge design is
resistant to aging and virtually insensitive
to thermal exposure and pressure cycling. The
stability of this technology assures the user of
high reliability with less than 0.2% drift per year.
All wetted parts are constructed of corrosionresistant 17-4 PH stainless steel, which makes
this unit ideal for use with corrosive media.
The Model 522 offers 0.25% FS accuracy
(optional 0.15% FS), compensated temperature
range of -5°F to +180°F (-20°C to 80°C), gauge,
absolute, and compound pressure ranges from
-14.7 psi up to 6000 psi.
The Model 522’s modular design is offered in a
wide choice of millivolt, voltage or current
outputs over almost any pressure range, and a
variety of pressure and electrical connections,
enabling this unit to be custom configured for
your OEM application.

Depending upon the electrical connection
selected, when coupled with the Model 522
enclosure, which is fabricated in 316 SS/17-4
PH SS, this unit is rated for IP65 or IP67
operation.
Principle of Operation
Using the well proven Wheatstone Bridge
principle, a chemical vapor is deposited in thin
layers of silicon and silicon dioxide onto a
stainless steel sensor to form a very sensitive
and accurate polysilicon strain gauge. The
elements of the strain gauge are fused
together at the atomic level, assuring the
strength and integrity of the bond, which
exceeds the adhesives used in common
bonded strain gauge pressure sensors. A
custom designed ASIC performs signal
amplification and temperature calibration.This
technology offers the user the option of
configurable output and pressure ranges, sets
the zero and span tolerance, and ensures
interchangeability from unit to unit.
