Highest Lightning, Surge, Overvoltage Immunity || No Earth Ground Bond
MOBILTEX CorTalk RMU devices have continually proven themselves to provide the highest level of lightning resistance, surviving powerful strikes and continuing to transmit data—even when the rectifier is damaged, inoperable or destroyed.
Remote CP monitoring devices are typically installed on the outside or inside of a CP rectifier and many are powered directly from AC line power via a step-down transformer. But this arrangement leaves the remote CP monitoring device vulnerable to lightning strikes. To mitigate the impact of lightning, CorTalk RMUs are equipped to absorb transient currents and are not bonded to earth ground.
This type of design provides a high level of lightning immunity; increasing the chances that the device can survive a lightning strike and also improving the likelihood that it will remain operational without the need to reset breakers or replace overloaded components. These same principles also apply for the CorTalk RMU1 Cathodic Protection monitoring devices at test stations for bonds and coupons.
In some of these situations, the MOBILTEX RMU may also suffer damage and show heavy scoring on the measurement block and melting of the antenna housing. MOBILTEX incorporates a two-piece design in the RMU2 and RMU3 devices, comprised of a measurement block that is installed inside the rectifier, and a compact, discrete antenna that is mounted on top. But in many instances following a lightning strike, the RMU is still functioning and transmitting accurate data at the scheduled intervals—the observed damage is cosmetic. Once the devices are retrieved by a technician, they can be returned to MOBILTEX for testing and cost effective refurbishment, then returned to the field for many more years of service.
The separate measurement and transmission components of the RMU also provide a high level of future proofing. For example, technicians can easily replace the antenna to upgrade the device to new satellite or cellular communication protocols to ensure reliable, uninterrupted transmission of critical CP data. This occurred a few years ago as the industry advanced to the 4G network. Fortunately, the LTE-M protocols that are used for 4G networks are being adopted for the incoming 5G network. This means that any MOBILTEX remote monitoring device that is equipped with 4G LTE-M capability—either from the factory or through an antenna upgrade—will not require any hardware modification to transition to the 5G network.
