High Performance Pressure Transducers Gauge, Sealed Gauge and Absolute Pressure Off-Highway Vehicles Natural Gas Equipment Semiconductor Processing Power Plants Heating, Ventilating & Air-Conditioning Refrigeration Robotics Benefits Superior Stability Avoids Down Time s 5:1 Range Turndown s High Overpressure Capability s etra’s Model 546 and Model 547 pressure transducers offer laboratory type pressure measurement in a rugged industrial housing complete with 5:1 range turndown, ideal for high overpressure applications, to provide full scale output from 25% to 125% of full range. Utilizing thin film technology, Models 546 and 547 have 4 to 20 mA output, 0.1% Full Scale accuracy, high overpressure capability, choice of absolute, gauge, or sealed gauge pressure measurement, and pressure ranges from 10 psi up to 10,000 psi. The compensated temperature range is from -13°F up to +167°F. Designed for use with corrosive media, the Models 546 and 547 are offered with 17-4 PH stainless steel or Inconel (17-4 PH and 15-7 Mo for ranges ≤30 psi) wetted parts to provide years of maintenance free pressure measurement in demanding industrial applications. (Order Model 547 for pressure transducer with Inconel® wetted parts.) Depending upon the electrical connection selected, when coupled with the Model 546/ 547 enclosure, which is fabricated in 321 SS, 174 PH SS, and Glass-Filled Polyester, this unit is rated for IP40, IP65, or IP68 operation. Thin Film Strain Gauge Pressure Sensors Using the well proven Wheatstone Bridge principle, molecular layers are sputtered onto a 17-4 PH stainless steel diaphragm and the circuit is etched to provide excellent resistor definition and uniformity. Sputtered thin film technology allows the design of simple, highly accurate and compact strain gauges depositied onto the back of the sensing diaphragm which is in direct contact with the media. This method virtually eliminates drift, while offering enhanced sensitivity.
