Pipeline Integrity Temperature Sensor Package for Remote Monitoring at Rectifiers
Introducing the CorTalk RMU3+TS1
Robust, reliable, and cost-effective temperature monitoring of pipeline assets is now available from MOBILTEX, engineered for performance in even the most extreme and remote locations.
MOBILTEX introduces the CorTalk RMU3+TS1 — a complete RTD Sensor/Transmitter Package that allow operators to easily add up to 12 sensors to new or existing RMU3 installations!
The MOBILTEX TS1 configurations enable field technicians to permanently install remote, GPS-enabled temperature sensing capabilities that are compatible with our CorTalk RMU1 [battery powered] or RMU3 platforms. Measurement data is accessible 24/7 within our CorView Platform cloud-based interface to enhance pipeline integrity data collection and help ensure the fitness of the pipeline in locations that have historically been cost-prohibitive to monitor.
Accurate temperature monitoring on multi-product lines requires wide temperature ranges, depending on the product and the season. The TS1 RTD transmitter connects to any standard Pt100 resistance sensor, is fully configurable, and provides high stability over an extremely wide range making it ideal for any field application.
The MOBILTEX TS1 enables pipeline engineers to easily and cost effectively monitor for extreme temperature fluctuation to identify risks of accelerated pipe coating deterioration and identify potential geohazard events where soil and moisture conditions shifts have occurred affecting normal temperature, which may have also damaged the pipeline. The TS1 also will allow users to monitor for pipeline temperature variances to enable more accurate calculation of volumetric flow for leak detection system calibration.
| Features | Benefits |
|---|---|
| Fast, simple installation | The compact, weather-proof RMU3 is designed for the measurement terminal to easily fit inside a rectifier cabinet or a NEMA4 enclosure with an external antenna that has been tested and proven in the most extreme applications – the system can typically be installed in under an hour. |
| Designed for high accuracy and resilience | External analog channels are high impedance and galvanically isolated with multistage lightning protection. AC rejection filters utilized for DC measurements to provide maximum accuracy. Several voltage ranges to accommodate a wide range of sensors (current shunts, reference cells, and direct voltage measurement) |
| Intelligently engineered with additional functionality | RMU3 platform has an AC Line Presence Sensor available to determine voltage is present, a magnetic sensor on enclosure doors that will alarm when unauthorized tampering occurs, an optional Measurement Recorder to capture analog readings, and a 4-20mA mode to receive signals from external equipment like the MOBILTEX TS1 temperature sensor. |
| Engineered for ease-of-use | Compatible with any RMU3, the TS1 temperature sensor package can connect to any standard Pt100 resistance sensor and is fully configurable, provides high stability, and can monitor pipeline or soil temperature |
| Multiple pre-defined configurations | The RMU3 can be utilized at test points and bond monitoring applications, in addition to the more conventional rectifier, TEG and solar applications. AC mitigation systems can also be monitored with an optional AC current transformer. |
| Intuitive controls and configurations | The RMU3 comes standard with an external “TEST” button and dual colour LEDs for manual controls. It can be easily programmed with our standard Programming Interface and a PC and can also be completed with a compatible iOS or Android-based mobile device and our available Bluetooth Interface. |
| Global communication capabilities | Available with cellular or satellite communication capability, the RMU2 can transmit data from virtually any location. This helps improve the quality and frequency of data collection, while reducing the need for workers to undertake long, potentially dangerous trips, to remote sites. |
| Smart readings and transmissions | To minimize airtime costs, the RMU2 stores four sets of periodic readings and then transmits all of those readings via four available factory-configured satellite or cellular data transmission plans. Irrespective of data plans, the RMU3 takes measurements every 6 hours, the device will immediately initiate a transmission when an alarm condition is detected. Alarms can be suppressed during interruption. |
| Built to withstand the toughest conditions | Lightning, surge and overvoltage protection and broad operating temperature range (-40° to +60°C [-40° to +140°F]). |
| Integral battery backup system | Powers the device for approximately 16 hours (RMU3-G) or 10 hours (RMU3-S) during power outages. |

Frequently asked questions
Can I use the rectifier taps to power the RMU3-B?
No. It is not recommended due to less electrical isolation. CSA/UL installations require a class 2 energy limited power source. Power your RMU3 from the AC mains with our custom transformer available from Mobiltex which has breakdown voltage of 5000VRMS for improved lightning immunity (typical is only 1500VRMS). Mobiltex Part Number: T01A42TR201
Do I connect one wire from the RMU power transformer to earth/functional/chassis ground?
No. Select the two appropriate color of wires required for your input voltage. Cap off the unused wires individually.
For example, when using the TR20VA020 Transformer (Mobiltex Part Number: T01A42TR201):
120VAC: Connect the black and white wires across the hot and neutral 120VAC lines
240VAC: Connect the black and orange wires across the hot 240VAC lines
What does a flashing green LED on the RMU3-B indicate?
When the multi-purpose LED is flashing green, it will depend if the device was recently transmitting:
- If the RMU3 recently transmitted, the flashing green LED indicates it is waiting for an acknowledgement from CorView. Once the RMU3 receives the acknowledgment, the green LED will turn solid green.
- If the RMU3 is not transmitting, the flashing green LED indicates that the most recent reading is outside of the programmed measurement limits (alarms)
