Multi-Range General Pressure Transducer: Model MRG

Multi-Range General Pressure Transducer

Product Overview

The Setra Model MRG is Setra’s newest differential pressure transducer. The Setra MRG is the ideal product for any contractor, combining the flexibility of a multi-range with the performance of a single range transducer. The MRG has 8 selectable ranges and 3 selectable outputs, easily adjustable on the job with a flip of a switch or jumper. The MRG uses an IP67 rated housing and has a conduit fitting for easy wiring, making the MRG an ideal solution for any general HVAC application.

Universal Design - The Setra MRG utilizes a universal design that gives the user total flexibility to make changes on the job site. The user has the option to choose the field configurable range, mounting (DIN Rail, wall mount and duct mount), output (mA or Volt) and engineering unit (W.C. or Pascals). This flexibility means that the contractor can use the MRG for all of their needs.

8 Field Selectable Ranges - The Setra MRG provides 8 field selectable ranges (0.5, 1.0, 2.5 and 5.0”W.C.). These ranges can be selected on site by flipping to the desired range.

IP67 Rated Housing - The MRG housing is a robust IP67 rated design and is sealed with a gasket to make it wash-down capable for difficult applications.  The MRG also has a conduit fitting that make installation and wiring easier.

Capacitive Sensing Technology - Only Setra can claim ownership to the stainless steel capacitive design used in all of our HVAC/R sensors.  Our advanced capacitive element provides excellent stability and linearity, while standing above the competitors in our ability to measure low pressure (<.0001 in. W.C) at high accuracy (0.25%).  Our technology has been used in over 8 million installations and has the highest field acceptance rate in the industry.
