Setra 516 Features
- Superior Stability Avoids Down Time
- Insensitive to Pressure Spikes
- 0.5 MS Response Time
- ±0.5% FS Accuracy
- Intrinsic Safe Option
- High Shock Resistance
Setra’s Model 516 OEM pressure transducer is designed for demanding industrial applications that are subjected to pressure shock, spikes and also 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 unit exceptional proof pressure up to 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, the 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 Setra’s 516 enclosure is fabricated in SS316 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 at the atomic level, assuring the strength and integrity of the bond, which exceeds the adhesives used in standard 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 to set the zero and span tolerance and ensure interchangeability from unit to unit.
