LEMA: Production Line Testing
Electro-magnetic Linear Actuator
Roehrig Engineering produces a fully automated test station
for in-line production testing of damper performance.
The unit pictured has a three station, rotating feeding unit
for doing a two speed test every 6 seconds. A user
defined pass fail analysis is done and damper determination
done.
Testing is done with Roehrig Engineering's EMA series,
however, any of our units could be adapted depending on wave
form specs, power and velocities required.
The EMA was used in this case due to varying stroke of the
two stage test.
The system pictured above was installed over two years ago. It
replaced a competitor's system with a more compact, less expensive
to maintain and more repeatable piece of equipment. It has
since run around the clock and logged over 10,000,000 cycles.
It uses a three station table, automatic grippers, PLC control and
analysis designed by Roehrig Engineering.
