Wireless Busbar Temperature Monitoring System
Catch hot joints before they turn into outages. Our wireless sensors watch every busbar connection inside your switchgear around the clock and alert your team the moment a temperature starts to climb.
Everything you need to keep busbars running cool
Continuous readings from every joint, so a loose bolt or overloaded section shows up the moment it starts heating, not at the next shutdown.
No signal wiring inside high-voltage compartments. Sensors transmit by RF to the controller, which keeps installation fast and safe.
The panel-mounted controller shows live temperature and battery status for each sensor and switches relays to drive hooters, fans or trip circuits.
Every reading is available over RS485 Modbus, so it drops straight into the SCADA, HMI or building management system you already use.
Send data through a gateway to the cloud for remote dashboards, temperature trends, analytics and alert notifications from anywhere.
Strap-on, battery-powered sensors fit new panels and existing installations alike, with no drilling or busbar modification.
What is WBTMS?
Busbar joints are the weakest point in any power distribution panel. Loose connections, oxidation and overloading raise contact resistance, and the heat builds up silently until insulation fails or a fire starts. Periodic thermography only gives you a snapshot, and it often means opening live panels.
The Amptronics Wireless Busbar Temperature Monitoring System (WBTMS) puts a small wireless sensor on each critical joint. A controller inside the panel collects the readings, raises local alarms and passes the data on to SCADA or the cloud, so maintenance teams can act on facts instead of fixed schedules.
