Model 546/547

Model 546

High Performance Pressure Transducer


Product Overview

Setra's Model 546/547 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, the 546/547 have a 4 to 20 mA output, 0.1% FS 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 is from -13°F up to +167°F.  Designed for use with corrosive media, the 546/547 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, 17- 4 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.
