etra’s Model 567 high performance
pressure transducer offers customer
accessible down-ranging capabilities,
making this unit ideal for high overpressure
applications. The 5:1 turndown is easily
accessed via a switch and potentiometer.
The Model 567’s CVD strain gauge design is
resistant to aging and virtually insensitive
to thermal transients and pressure cycling.
The stability of this technology assures the
user of excellent reliability with less than
0.15% drift per year.
All wetted parts are constructed of
corrosion-resistant 17-4 PH stainless steel,
which makes this unit ideal for use with
corrosive media.
The Model 567 offers 0.15% FS accuracy,
compensated temperature range of 15°F to
+120°F (-10°C to 50°C) for 0.5% of maximum
span, and -4°F to 176°F (-20 to 80°C) for 1%
of maximum span. Operating media
temperatures as low as -22°F to 212°F (-20°C
to 50°C), and gauge, and absolute pressure
ranges from 15 psi up to 6000 psi.

The Model 567’s modular design is offered in
a wide range of voltage or current outputs 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 567
enclosure, which is fabricated in 321 SS, 17-4
PH SS, and Polyester, this unit is rated for IP40,
IP65, or IP68 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 diaphragm 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.
