Dwyer Instruments MS Magnesense Series Specifications-Installation And Operating Instructions

The Series MS Magnesense
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 and the ability to select a square root
output for use with Pitot tubes and other similar flow sensors.
Also, a single digital push button simultaneously calibrates
both zero and span reducing installation and setup time. These
features along with exceptional long term performance
enables the Magnesense ®
pressure and air flow applications.
INSTALLATION
Mounting:
The transmitter should be mounted on a vertical surface with
the connections directed down to prevent moisture from enter-
ing either the pressure ports or the electrical cable entry.
Mount the transmitter using #8 x 1/2˝ pan head sheet metal
screws in the mounting flanges. Do not over tighten.
Electrical Connection:
2-Wire Operation:
CAUTION: DO NOT EXCEED SPECIFIED SUPPLY
VOLTAGE RATINGS. PERMANENT DAMAGE
NOT COVERED BY WARRANTY WILL RESULT.
2-WIRE UNITS ARE NOT DESIGNED FOR AC
VOLTAGE OPERATION.
