Which company should I choose for temperature measurement of busbar trunking in power distribution cabinets

Eaton, SenseLive, AP Sensing, and Faclon Labs offer advanced busbar temperature monitoring solutions suitable for power distribution cabinets. Eaton DIAGNOSEEaton's DIAGNOSE system provides wireless, maintenance-free temperature monitoring for low-voltage switchgear assemblies. It uses energy-harvesting sensors that can be installed anywhere in the panel without additional power supply, offering 24/7 monitoring of busbar sections with ±2°C accuracy.

The system supports trend analysis, hot spot detection, and integration with SCADA/BMS via Modbus TCP. It is robust for industrial environments (-40°C to +70°C) and allows offline software updates and long-term data storage.

Sense

Live Wireless Busbar MonitoringSenseLive offers a wireless IoT-based system with real-time monitoring, predictive maintenance, and cloud analytics. It supports up to 60 sensors per controller, with both battery-powered and CT-powered options. The system provides instant overheating alerts, relay outputs, and integration with SCADA systems using Modbus-RTU or optional 4G connectivity.

Sensors operate in harsh conditions (-50°C to +125°C) and are IP68-rated, making it suitable for industrial, commercial, and utility-scale installations.

A

P Sensing Fiber Optic SolutionsAP Sensing uses fiber optic Distributed Temperature Sensing (DTS) technology for continuous monitoring of bus ducts and busbars. It provides precise hotspot detection, 24/7 monitoring, and integration with SCADA/BMS systems. The dielectric, passive fiber optic sensors can be installed directly on bare metal busbars and handle temperatures up to 150°C.

The system is ideal for high-load or critical applications where early detection of thermal anomalies is essential.

Faclon Labs Wireless Monitoring

Faclon Labs provides a wireless, battery-powered solution for continuous monitoring of busbar joints and terminations. It delivers real-time thermal heat maps, proactive SMS/email alerts, and operates safely on high-voltage lines up to 33kV. The system eliminates the need for manual thermography, reduces technician exposure, and supports long battery life (4–5 years), making it suitable for industrial plants requiring reliable, continuous monitoring.

Selection Considerations

When choosing a company or system, consider: Voltage level and environment: Low-voltage vs high-voltage switchgear, ambient conditions. Sensor type: Wireless, battery-powered, CT-powered, or fiber optic. Integration: Compatibility with SCADA/BMS and cloud platforms.

Maintenance: Battery life, energy harvesting, or maintenance-free operation. Accuracy and range: Ensure sensors cover expected busbar temperature ranges. Standards compliance: IEC, IEEE, NB/T, or NFPA guidelines.

For industrial or high-voltage applications, AP Sensing and Faclon Labs provide robust continuous monitoring. For low-voltage switchgear with flexible wireless deployment, Eaton DIAGNOSE or SenseLive are strong options. The final choice should align with your system voltage, monitoring requirements, and integration needs.
