Setra'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.
