Cost effective obstruction detecti
August 1st 2008

Hoerbiger-Origa's design team has applied its experience of producing obstruction detection solutions for the rail industry to industrial and manufacturing worlds.

"Our rail doors operate by monitoring the back pressure in the pneumatic cylinders that drive the doors to and fro," explains Hoerbiger- Origa's Mark Prew. "In normal operation the pressure remains within specific operating limits, but the back pressure will rapidly drop away if an obstruction is detected. It's simple to detect this change in pressure and rapidly reverse the flow of air to reopen the doors minimising contact time against the obstruction." Mark explains: "We have developed a system that is suitable for a wide spectrum of applications. It provides a cost effective alternative to more complex detection systems while maintaining many of their functions."
