Description

Description The RMU1 collects and transmits CP performance data and GPS location as frequently as every few hours via satellite or cellular network. This provides technicians with a highly detailed, near-real-time view of the CP system and helps identify short-lived events that may impact CP performance. When combined with the Mobiltex CorView web analytics platform, pipeline operators can implement a network of RMU1 devices to gain deep insight into the performance of the CP system, generate reports and instantly identify areas of concern. RMU1 Generation 4 is also capable of two-way communication and can provide remote, GPS-synchronized interruption with the addition of MOBILTEX INT1, a compact accessory module. Key Features/strong> Fast, simple installation; typically under 20 minutes Configurable as a CP coupon or critical bond remote monitor Multiple analog measurement channels provide accurate measurements for all required AC and DC parameters A user-replaceable battery provides up to 10 years of monitoring, data transmission and helps maximize lightning isolation Satellite or cellular transmission with cost-effective communication plans Intuitive configuration using any web-enabled device Generation 4 hardware platform allows connection of additional external accessory modules LEARN MORE AT MOBLITEX.COM/RMU1 Features Simple and very quick to install (typically under 20 minutes) Low capital equipment cost and high product reliability Economical fixed rate operational communications costs Satellite communications for maximum service coverage Configurable as a CP coupon or critical bond remote monitor Configurable measurement transmission rate Test station GPS position information transmitted to corView host Measures coupon AC current density, coupon DC current, coupon AC & DC potential, instant-disconnect coupon DC potential, depolarized coupon DC potential, native coupon DC potential, bond AC & DC current, and second structure DC & AC potentials Configurable instant-disconnect measurement delay Configurable coupon depolarization time Internal temperature measurement and reporting DC measurements have >65dB of 50/60Hz AC rejection for and accurate readings True RMS AC measurements High measurement accuracy specified over full temperature range Lightning and surge protected No connection to Earth ground for maximum lightning immunity 3½ digit wide-temperature LCD for local measurement display Easy configuration through a PC application Powered exclusively from a low-cost user replaceable internal battery for maximum lightning isolation and installation simplicity Primary battery will last for more than ten years based on readings transmitted every week Small size 3.1" diameter x 4.4" (79mm diameter x 112mm) allows use within most standard CP test stations with supplied cap extender Optional screw-on cover provides flush mounting inside 3" PVC pipe without the need for a test station IP65 waterproof non-submersible enclosure Operating temperature range -40 to +140°F (-40 to +60°C)
