UniPro™ Explosion Proof
Railcar Motion Detector System
The UniPro™ Explosion Proof Motion Detector System is designed to mount on
the loading/unloading platform in close proximity to the tank car being serviced.
The spool holds 25 feet of stainless steel braided cable and the locking mechanism
on the reel prevents excess cable from unwinding in the event of tank car motion.
The cable can be routed around any solid object on the tank car and clipped to the
pin underneath the reel. The pin is inserted through a rotating fixture above an
explosion proof (Class 1, Div 1) switch.
How the Motion Detection System Works
In the event of tank car motion, the pin is pulled free, releasing the switch. The
rotating fixture assures that the pin will be pulled straight out regardless of
the direction of tank car motion.
The signal from the switch activates the UniPro™ Valve Closure System, which
quickly responds by closing the valve within seconds.
