Model 522 Industrial OEM Pressure Transducers Gauge, Absolute, and Compound Pressure Applications General Purpose q Off-Highway Vehicles q Industrial OEM Equipment q Hydraulic Systems q Pumps and Compressors q Industrial Engines q Process Applications q Benefits Superior Stability Avoids Down Time q ±0.25% FS Accuracy (Optional ±0.15%) q Millivolt, Voltage, or Current Outputs q IP65 and IP67 Rated q Meets CE Conformance Standards q 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.
