etra System’s Model 526 General
Purpose pressure transducer is
S
designed with a thicker diaphragm
for robust industrial and submersible
applications that require exceptional stability
and high accuracy.
The Model 526’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 high reliability with less than 0.2% drift
per year.
Depending upon the electrical connection
selected, when coupled with the Model 526
enclosure, which is fabricated in 316 SS/17-4
PH SS, this unit is rated for IP30, IP65, or IP68
operation.
The Model 526 offers 0.25% FS accuracy
(optional 0.15% FS), compensated temperature range of -5°F to +180°F (-20°C to 80°C),
and gauge, absolute, or compound pressure
ranges from -14.7 psi up to 6000 psi.
The Model 526’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.
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 compensation.
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.
