The Series MS2 Magnesense® II Differential Pressure Transmitter combines the proven stable piezo technology and the versatility of our original Series MS with additional features to reduce installation time and simplify ordering. Like the original Series MS, the second generation transmitter can be used as a linear pressure output or a linear velocity output with the square root extraction done in the transmitter. Additional parameters have been included to expand the square root capability to include flow measurements.

• Field selectable ranges and output signal reduce inventory and the chances of ordering an incorrect part
• BACnet® or Modbus® serial communications reduce wiring cost by daisy-chaining the transmitters
• Our integral field-upgradeable display or plug-in remote display tool save upfront material cost and allow for local viewing of measurements
