Dwyer Instruments Magnesense MSX Series Installation And Operating Instructions Manual

Series MSX Magnesense
Specifications - Installation and Operating Instructions
The Series MSX Magnesense Differential Pressure Transmitter combines the
®
stability and versatility of the original Series MS2 Magnesense
in building control applications. The MSX simplifies the ordering process to deliver the
desired configuration, which reduces product setup time. Pressure ranges are available
in Pa, mm w.c., and in w.c. All pressure ranges can be configured in unidirectional or
bidirectional modes, providing a total of 32 ranges. The MSX transmitter can provide
a linear pressure output or a linear velocity output with the square root extraction from
the transmitter. Additional parameters have been included to expand the square root
capability to calculate flow. Dual voltage and milliamp output signals can be used to
provide both control and equipment output signal verification.
INSTALLATION
Surface Mounting:
Mount the transmitter on a vertical surface. The pressure sensor measurement
is unaffected by orientation, but it is recommended the unit be mounted with the
connections facing down to prevent moisture from entering either the pressure ports
or the electrical cable entry. Attach the mounting flange to a flat surface using #8 x 1/2˝
pan head sheet metal screws. Do not over tighten.
Duct Mounting (Universal model required):
Mount the transmitter away from fans, corners, heating and cooling coils and other
equipment that will affect the measurement of the pressure.
1. To mount the transmitter, drill a .562˝ (12.70 mm) diameter hole into the duct.
2. Screw duct probe into back of housing. Insert transmitter probe into the duct.
3. Mark location of mounting holes on duct using mounting flange as template. Drill
holes.
4. Attach mounting flange to duct with #8 x 1/2˝ pan head sheet metal screws. Do
not over tighten screws.
5. Place the included cap on the exterior positive pressure port.
The Universal model can also be used as a standard wall mount transmitter. In this
mode, do not use the duct probe and plug the port on the backside of the transmitter
with the included plug.
