The OmniMetrix Rectifier Monitor (RM) is a self-contained, wireless remote monitoring unit for C Rectifiers. It measures rectifier output voltage and rectifier shunt current, and includes AC control power detection. A reference cell input allows pipe-to-soil and potential to structure measurement. Add-on modules allow additional inputs, remote current and voltage adjustment, and GPS-synchronized group interruption.

Lightning damage is avoided by the exclusive OmniMetrix StormSense™ module, which monitors the ionosphere for lightning activity. When an approaching thunderstorm is detected, StormSense™ causes input relays of the RM Rectifier Monitor to electrically disconnect the unit from the Rectifier, from the reference cell, and from AC control power. This protects the unit from lightning damage. The unit also automatically disconnects in the event of AC power line disturbances.

The RM Rectifier Monitor features wide-area connectivity via digital radio, transmitting data wirelessly to the OmniMetrix secure website. No custom software is required; all you need is a PC with Internet Explorer. The RM Rectifier Monitor compares its input measurements to preset alarm levels, and can deliver alarms upon detection of out-of-bounds conditions. Alarm levels and reporting intervals are remotely programmable.

OmniUpdate™ is an OmniMetrix exclusive that performs remote updates. No need for field laptops - the RM's firmware is automatically updated over the life of the monitor.

The RM Rectifier Monitor is housed in a NEMA-4X enclosure and includes pole-mounting hardware. The rectifier voltage and current inputs have automatic dual-scale selection for superior accuracy. The Gel Cell backup battery features a smart charging system with battery life test, promising the longest possible battery replacement interval. An integral Tamper detection function will automatically and instantaneously awaken the unit and cause a Tamper Alarm transmission. This function is utilized for security against unauthorized intrusion of the monitor.
