The OmniMetrix Pipe-to-Soil Monitor (PSM) is a self-contained wireless remote monitoring unit for pipe-to-soil and potential to structure CP test station measurements. The PSM monitors the reference electrode output, giving scheduled data reports and alarm notification in the event of extreme CP readings.

The PSM 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 monitor compares its input measurements to preset alarm levels, and can deliver alarms upon detection of our-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 PSM's firmware is automatically updated over the life of the monitor.

The PSM may be direct-buried in the soil, with only a 5” dome visible above the soil. It is also available in polemount or test-station cap versions. Enclosures are by Cott Manufacturing. Power is provided by a 10-year Lithium battery.

An integral Tamper detection function automatically and instantaneously awakens the unit and cause a Tamper Alarm transmission. This function is utilized for security against unauthorized intrusion of the monitor.

Farwest also offers a complete PSM kit, which includes a riser clamp and a GMC bagged reference cell.
