The Series MS Magnesense® Differential Pressure Transmitter is an extremely versatile transmitter for monitoring pressure and air velocity. This compact package is loaded with features such as: field selectable English or metric ranges, field upgradeable LCD display, adjustable dampening of output signal (with optional display) and the ability to select a square root output for use with Pitot tubes and other similar flow sensors.



  • Field Upgradeable LCD. No need to order two separate transmitters. Simply stock a transmitter and display and you can satisfy any customer's requests. Simply remove cover and snap the LCD onto the board.
  • Field Selectable Ranges in English or Metric. Lowers stock and inventory requirements. You'll always have the right transmitter for every job.
  • Digital Push Button Zero and Span. Reduces calibration time significantly over other transmitters that utilize potentiometers. Lowers maintenance time and costs.
  • Adjustable Digital Dampening smooths out unstable pressure fluctuations common in air flow applications.
  • Field Selectable Air Velocity Mode for fan and blower applications. Unit provides square root output that accurately tracks fpm or m/s flow rate. No need for a smart programmable indicator or PLC to convert pressure to air flow. Reduces components and installation time lowering overall costs.
