Sensor gives precise control of blow molding clamp

Graham Engineering has standardized on Balluff’s non-contact Micropulse linear position sensor for both its accumulator head and indexing wheel blow molding machines. The Micropulse offers precise, repeatable position feedback at sub-millisecond update times. Each platen on Graham machines is controlled by a dedicated servo valve and is monitored by a Micropulse.

“The dual-servovalve system gives us total control over both platens, not just control over one while the other is tethered along for the ride,” says Bill McKeon, Graham Engineering project manager.

The Micropulse is extremely repeatable and reliable because it is not affected by oil or dirt, is temperature-resistant, shock and vibration-resistant and has flexible mounting and output, with analog voltage and current, and digital pulse interface, allowing for the optimal configuration for each particular component.
