3 OD 9 Rating: Orientation: Diaphragm in vertical : oz (230 g).Agency Approvals: BTL, Series MS2 Magnesense II Differential Pressure Transmittercombines theproven stable Hall Effect sensing technology of our original Series MS with additionalfeatures to reduce installation time and simplify ordering. In this second generationtransmitter, we have added additional field selectable Pressure ranges so that each modelcan have four selectable ranges along with four additional bidirectional ranges. When usingthe pluggable integral display or the portable remote display tool, both Metric and Englishengineering units can be selected via on board dip switches.

4 Dual current and voltageoutputs allow users to simultaneously take either a current or voltage output to theirbuilding controller and have a local test circuit for verification of the output reading. Thevoltage output can be selected to be either 0 to 5 VDC or 0 to 10 VDC, while the current isalways 4 to 20 mA. Both the current and voltage output can also be inverted. The MS2can also be ordered with either a BACnet or MODBUS Communications protocol outputthat will allow the transmitters to be daisy-chained the original Series MS, the second generation transmitter can be used as a linearpressure output or a linear velocity output with the square root extraction done in thetransmitter.

5 Additional parameters have been included to expand the square root capabilityto include flow and Modbus Communications protocol recommend limiting the number of nodesin any segment to 32. Therefore, the transceiver may be rated at one unit load. Fractionalloads are also acceptable.
