Setra’s model 540/542 Series pressure transducers are designed for harsh applications that require long-term service and high performance. Utilizing thin film technology, the Models 540/542 offer choice of 0.1% full scale or 0.08% full-scale accuracy, millivolt output, a wide compensated temperature range from -65o F up to +250o F, and gauge, sealed gauge, and absolute pressure measurement for pressure ranges 15 psi up to 10,000
psi (1 bar up to 690 bar). Differential pressure measurement is available in ranges from 15 psid up to 300 psid. All wetted parts are constructed of 17-4 PH SS or Inconel for ranges 15 psi up to 6000 psi (1 bar and 400 bar). (Pressure transducers ordered in 600 or 690 bar and 10,000 psi ranges are only available with Inconel wetted parts.) Specify Model 540 when ordering a pressure transducer with stainless steel wetter parts, and Model 542 with Inconel.

Model 540/542 are offered with choice of 10-6-Pin Bayonet Connector, Weatherproof Cable, and Molded Submersible Cable (submersible up to 656ft.) for electrical termination. Depending upon the electrical connection selected, when coupled with the Model 540/542 enclosure, which is fabricated in 321 SS, this unit is rated for IP40, IP65, IP66, or IP68 operation. Requiring virtually no maintenance, the stability of this unit assures the user of high reliability, with less than 0.06% drift per year.
