Module unlocks potential of smart HART
Moore Industries' HIM smart HART loop interface and monitor allows up to three additional analogue process measurements from smart HART multivariable mass flow, level, pressure and pH transmitters.
With no additional process penetrations or wiring, Moore Industries' HIM smart HART loop interface and monitor allows up to three additional analogue process measurements from smart HART multivariable mass flow, level, pressure and pH transmitters For a multivariable mass flow transmitter, this may include pressure, differential pressure, process temperature, flow rate, flow total and sensor temperature

System provides secure wireless connectivity
Moore Industries' WLM employs frequency hopping spread spectrum technology and 32-bit CRC error correction for secure, robust communications.
Flexible sensors save time and money
The Worm sensor slides through the enclosure's entry port, and snaps into place without removal of the enclosure, rigid conduit, connection head or any assembly components.
Using the HART digital data that "rides" on the 4-20mA wires, the HIM "breaks out" up to three 4-20mA signals representing any combination of a smart multivariable transmitter's primary, second, third, or fourth measurement variables so they can be used by analogue control systems, such as a DCS or PLC.
Dual alarm trip outputs can be individually configured to warn of high/low process conditions.
They can also be set to alert the user if the monitored device and/or the HART monitor itself is in a fault condition.
This includes use of the HART protocol's status bits to indicate a smart transmitter cold start; field device malfunction; or that the primary variable analogue output is fixed, saturated, or out of limits.
The HART Interface and Monitor sets up quickly and easily using Moore Industries' single window configuration software equipped with HelpMap, a comprehensive, searchable web-based help system that smoothly guides the user from hookup to startup.
The compact, DIN-rail mount module installs on a rail in the control room, or in rugged field conditions in the company's metal R-Box field-mount enclosure.
