Setra's Model 516 OEM pressure transducer is designed for demanding industrial applications that are subjected to pressure spikes, shock and vibration caused by the harsh physical and environmental conditions of industrial applications.
The Model 516’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. This units exceptional proof pressure is 4 x full scale with less than a 1.0% zero shift. 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 516 offers 0.5% FS accuracy, compensated temperature range of -5°F to +180°F (-20°C to 80°C), and gauge or compound pressure ranges from -14.7 psi up to 6000 psi. The Model 516’s modular design is offered in a wide choice of 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.
The 516 enclosure is fabricated in 316SS and 17-4 PH SS, and rated for IP65 operation when mated with the 8-4 or 10-6 Bayonet connector, or large DIN 43650 connector, and IP30 when mated with the 1/2” Conduit Connector w/ flying leads.
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 per forms 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.
