Differential Pressure Transmitters

Differential Pressure Transmitters convert pressure difference between two ports into an electrical signal for controls and monitoring. Products in this category span ACI, Omega Engineering, and Dwyer Instruments low differential transmitters for airflow and filter monitoring, panel-mount devices, 4 to 20 mA air and gas transmitters, wet/wet and wet/dry transducers, and compact duct pressure transmitters.

Applications include:

  • Building airflow and duct static pressure control
  • Filter, coil, and fan pressure drop monitoring
  • Cleanroom, data center, and critical room pressure systems
  • Wet/wet, wet/dry, and process differential pressure measurement

Choose by range, media, output, accuracy, mounting, calibration access, and whether the application is low-pressure air or industrial process service.
