Dwyer Magnesense II differential pressure transmitter

Click2Contact

The Series MS2 Magnesense II differential pressure transmitter combines the Hall effect sensing technology of Dwyer’s original Series MS with additional features to reduce installation time and simplify ordering.

In this second-generation transmitter, additional field-selectable pressure ranges have been added so that each model can have four selectable ranges along with four additional bidirectional ranges.

When using the pluggable integral display or the portable remote display tool, engineering units can be selected via onboard DIP switches. Dual current and voltage outputs allow users to simultaneously take either a current or voltage output to their process controller and have a local test circuit for verification of the output reading.

The voltage output can be selected to be either 0-5 VDC or 0-10 VDC, while the current is always 4-20 mA. Both the current and voltage output can also be inverted.

The MS2 can also be ordered with either a BACnet or Modbus communications protocol output that will allow the transmitters to be daisy-chained together.

The 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.
