BENTLY 136711-01

Description

1. Product overview

The BENTLY 136711-01 is a key component in BENTLY’s machinery monitoring and protection systems, specifically a junction box designed for seamless integration with proximity probe systems. It serves as a centralized connection point, facilitating the efficient and reliable transmission of signals from multiple proximity probes to monitoring units. This junction box is essential in industrial settings where numerous rotating machinery components need to be monitored simultaneously, such as in power plants, oil refineries, and large manufacturing facilities. By consolidating the signals, it simplifies the wiring infrastructure, reduces the risk of signal interference, and ensures accurate data transmission, which is crucial for timely detection of machinery issues and maintaining operational efficiency.

3. Product features and technical highlights

Centralized signal management: The 136711-01 junction box offers 4 channels, allowing for the consolidation of signals from up to 4 proximity probes. In a large turbine system, for example, multiple proximity probes are installed to monitor different aspects of the turbine shaft, such as radial vibration, axial position, and eccentricity. By connecting all these probes to the 136711-01, the signals are centralized, simplifying the wiring layout. This not only reduces the complexity of the electrical system but also makes it easier to trace and troubleshoot any wiring issues, saving time during installation and maintenance.

Robust environmental protection: With an IP65 ingress protection rating and an aluminum enclosure, the junction box provides reliable protection against environmental hazards. In an oil refinery, where machinery is often exposed to dust, oil mist, and occasional water splashes, the IP65 rating ensures that dust cannot penetrate the enclosure, and water jets from cleaning operations will not damage the internal components. The aluminum construction resists corrosion from chemical vapors, ensuring long-term reliability in such harsh conditions.

Wide temperature tolerance: The ability to operate from -40°C to +85°C makes the 136711-01 suitable for extreme temperature environments. In a power plant’s boiler area, where temperatures can rise significantly, or in a cold climate outdoor installation, the junction box maintains stable performance. This temperature resilience ensures that the signal transmission remains unaffected, providing consistent and accurate data to the monitoring system regardless of the ambient temperature.

Flexible installation options: Supporting both surface mounting and DIN rail mounting, the 136711-01 can be easily integrated into various industrial setups. In a manufacturing facility with limited space, surface mounting on a nearby wall or machinery frame saves space. In control cabinets where DIN rails are commonly used, the junction box can be quickly mounted on the rail, ensuring a neat and organized installation. This flexibility allows for optimal positioning of the junction box to minimize cable lengths and simplify wiring.

4. Typical application scenarios

Turbine monitoring systems: In power generation plants, gas turbines and steam turbines require comprehensive monitoring of their rotating shafts. The 136711-01 junction box is used to connect multiple proximity probes installed on the turbine. For instance, probes monitoring the front and rear bearings’ radial vibration, as well as the axial position of the shaft, can all be connected to the 136711-01. The junction box consolidates these signals and transmits them to the main monitoring system, providing operators with a complete overview of the turbine’s condition. This enables early detection of issues like bearing wear or shaft misalignment, preventing costly turbine failures.

Pump and compressor arrays: In oil and gas processing facilities, multiple pumps and compressors are often arranged in arrays to handle the high volume of fluid transportation. Each pump or compressor may have 2-4 proximity probes monitoring their rotating components. The 136711-01 junction box can be installed near each group of machinery to collect signals from these probes. By centralizing the signals, it reduces the number of cables running back to the control room, simplifying the infrastructure and improving the reliability of data transmission. In case of a malfunction in one of the pumps, the monitoring system can quickly identify the affected unit based on the signal from the junction box.

Industrial motor monitoring: Large industrial motors used in manufacturing plants, such as those driving conveyor belts or machining centers, require monitoring of vibration and shaft position to ensure efficient operation. The 136711-01 can be used to connect proximity probes placed on the motor’s bearing housings. By consolidating the signals, it provides real-time data on the motor’s condition. If abnormal vibrations are detected, the monitoring system can trigger an alert, allowing maintenance teams to inspect the motor before a breakdown occurs, minimizing production downtime.

5. Installation and maintenance guidelines

Installation: Before installation, review the installation manual provided by BENTLY NEVADA to ensure compliance with all requirements. Choose a suitable mounting location that is close to the proximity probes to minimize cable lengths, and ensure the area is free from excessive vibration and extreme mechanical stress. Mount the junction box using either surface mounting hardware or a DIN rail, depending on the setup. Connect the cables from the proximity probes to the corresponding terminal blocks, ensuring proper polarity and secure connections. Route the main cable from the junction box to the monitoring unit, avoiding areas with high electromagnetic interference. Seal all cable entries to maintain the IP65 ingress protection rating.

Maintenance: Regularly inspect the 136711-01 junction box for signs of physical damage, such as dents or cracks in the enclosure. Check the cable connections to ensure they are tight and free from corrosion. Clean the exterior of the junction box periodically using a soft, dry cloth to remove dust and debris. In environments with high humidity or chemical exposure, inspect the enclosure for signs of corrosion and address any issues promptly. Verify the signal transmission by checking the data received at the monitoring unit. If any signal anomalies are detected, check the wiring connections within the junction box first. For persistent issues, refer to the troubleshooting guide or contact BENTLY NEVADA’s technical support.
