Setra Systems MR1DC Differential Pressure Transducer

The Setra MR1DC differential pressure transducer is a dry-differential pressure sensor that combines multi-range flexibility with Setra's precision sensing for HVAC and general air-flow applications. It offers eight field-selectable ranges (including 0.1, 0.25, 0.5 and 1.0 inW.C.) and three configurable outputs, allowing on-site tailoring without replacing the sensor. The MR1DC uses Setra's stainless-steel capacitive sensing element for stable, low-drift differential measurements across the selectable ranges. A four-digit LCD displays the measured differential pressure, and the unit supports field calibration via push-button zero and span. The enclosure is IP67/NEMA 4 rated and includes a conduit fitting, making it suitable for wash-down environments and harsh job sites. Installation is flexible with field-configurable mounting options (wall, duct, or DIN rail) and a field-configurable duct probe to fit various installations. Unregulated AC/DC operation provides power-supply versatility across commercial and industrial environments. The MR1DC is part of Setra's MR family, designed to deliver multi-range versatility with the reliability of a single-range sensor in one device.
