Description

Setra’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 transients 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 corrosion-resistant 17-4 PH stainless steel, which makes this unit ideal for use when corrosive media.  The Model 522 offers 0.25% FS accuracy (optional 0.15% FS), compensated temperature range of -5oF to 180oF (-20oC to 80oC), 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 milllivolt, 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 or 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.
