T500 Elite Hotbus™
Hazard Monitoring System for Bucket Elevators and Conveyors

         
 

The T500 Elite Hotbus™ is a serial communications system designed to monitor up to 256 sensors for combined belt alignment, belt speed, continuous bearing temperature, pulley alignment, level indication (bin / silo) and plug conditions on bucket elevators and conveyors.  With automatic machine shutdown capability and PLC / PC compatibility, this advanced microprocessor based system offers low cost installation, versatility and easy system expansion. Complete system data is available with HazardMon.com®.

HazardMon.com is a secure cloud based hazard monitoring solution providing status notifications and data logging for bucket elevators and conveyors. Live system status, graphs and historical data can be viewed on any web-enabled device (smartphone, tablet PC, desktop or laptop computer). Emails can be sent to notify users whenever a change in the system's health is detected. An automated maintenance feature allows site operators to verify that all sensors on the system are operational and working correctly.
