Setra’s Model MRC multi-range low differential pressure transducer uses a dead-ended capacitive sensing element that requires minimal amplification and delivers excellent accuracy and long-term stability. The MRC is the industry’s first multi-range sensor designed for critical environments. It is the only multi-range sensor available with ±0.5% FS accuracy and field selectable ranges down to 0.1” W.C., a requirement for critical applications. The MRC has 4 selectable ranges and 3 selectable outputs, easily adjustable on the job with a flip of a switch or jumper. The MRC is offered with 3 different mounting options: Duct Probe, DIN rail, or Wall Mount, and a universal design that incorporates all 3 configurations in one to address any installation changes on the job site.


Key Benefits

  • Industry First 0.5% FS Accuracy Multi-Range
    The Setra MRC is the first multi-range transducer designed for use in Critical Environments. No other multi-range transducer product offers better than 1% FS accuracy; a requirement in most critical applications. The Setra MRC is available down to 0.1” W.C. with 0.5% FS accuracy.
  • Field Selectable Universal Design
    The MRC has 4 selectable ranges and 3 selectable outputs, giving the flexibility to make changes on the job site. The MRC is field configurable for range, mounting (wall mount standard; DIN rail and duct versions optional), output (mA or voltage), and engineering units (W.C. or Pascals). This flexibility means that the contractor can use the MRC for all of their critical needs.
  • Robust Enclosure for Harsh Environments
    The MRC housing is a robust IP67-rated design and is sealed with a gasket to make it wash down and capable for difficult applications. The MRC can accommodate a conduit fitting that makes installation and wiring easier.
  • The Setra Sensor
    The core technology of the MRC is the all-stainless steel capacitive sensing element. Setra designs and manufactures all of their sensing elements resulting in full control over the process and quality of every single sensor. The welded dead-ended capacitive sensors require minimal amplification and deliver excellent accuracy and long-term stability. Setra’s technology has been used in over 8 million installations and has the highest field acceptance rate in the industry.
