Product Overview

Setra’s Model 512 OEM pressure transducer is designed to withstand pressure spikes, shock, and vibration caused by the harsh physical and environmental conditions of industrial applications. The Model 512’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.

The units exceptional proof pressure specification is 4x full scale with less than a 1.0% zero shift. The Model 512’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 applications.

Depending upon the electrical connection selected, when coupled with the Model 512 enclosure, which is fabricated in 316 SS/17-4 PH SS, this unit is rated for IP65 or IP67 operation. All wetted parts are constructed of corrosion resistant 17-4 PH stainless steel, which makes this unit ideal for use with corrosive media.

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.
