DP MR TRANS WET 0-25/50; 125/250 PSI UB

Setra’s Model 231 Multi‑Sense® Wet‑to‑Wet differential pressure transducer all inclusive design provides users with field accessible ranging, choice of output and field zeroing. Choose from three configurable Model 231 pressure transducers: 5 up to 50 psid, 10 up to 100 psid, or 25 up to 250 psid. Each Model 231 has 4 unidirectional and 4 bidirectional switch selectable pressure ranges and can be reconfigured in the field for 0‑5 VDC, 1‑5 VDC, 0‑10 VDC, or 4 to 20 mA output. (The 4 to 20 mA output is operable as a true 2‑wire device.) The Model 231 jumper selectable port swap feature eliminates costly replumbing if the pressure transducer is improperly installed or replaced. An optional LCD display is available for on‑site indication of line and differential pressure. The Model 231 is designed with Setra’s own dual pressure sensors, which incorporate thin film sensing technology. This technology offers exceptional thermal accuracy and signal linearity. Utilizing this technology, the Model 231 is resistant to long‑term drift caused by dopant migration and Fermi‑level effects, intrinsic in piezoresistive and silicon based technologies, which are exaggerated at elevated temperatures and by extended pressure cycling.
