Setra Systems Model 3100/3200 series pressure transducers

Setra Systems has introduced the Model 3100/3200 series, a family of compact, low-cost, high-pressure transducers, designed to support the rigorous performance demands of high-volume OEM applications, and particularly within space-constrained environments.

Available in standard (Model 3100) and heavy-duty (Model 3200) versions, the 3100/3200 series incorporates the use of thin-film strain gauge sensing technology in a Wheatstone bridge configuration.

The 3100/3200 series is available in standard duty ranges from 50 to 32,000 psi (4 to 2200 bar) with up to 3x overpressure protection. The Model 3200 heavy-duty version offers a thicker diaphragm and optional restrictor or snubber, making it operational in environments where extreme positive or negative pressure spikes may be of concern. Both versions offer 0.25% full-scale measurement accuracy, with long-term stability of better than ±0.1% FS per year, over an operating temperature range of -40 to +105°C.

The series is available with the choice of mA, voltage or ratiometric output. Voltage output versions are available with dual temperature and pressure outputs for both models. Its small diameter, measuring less than 25 mm, allows for ease of installation within space-constrained environments. Units are reverse-wire protected. They are also UL listed, meet CE and EMC standards, and are fully RoHS compliant.

The series is suitable for larger volume, low-cost OEM applications, including medical devices and diagnostic equipment, hydraulic and pneumatic systems, HVAC/R compressors, variable speed pumps, refrigeration systems, industrial pumps and general industrial pressure monitoring applications.
