Adjustable Machine Height Monitor

 

SMH – 4 or 8 / AMH – 4 or 8

Helm series SMH and AMH Adjustable Machine Height Monitors are based on Allen Bradley PLC controllers, to accurately monitor and control adjustable motor driven machine height. Precision linear transducers are mounted on the machine, to measure the adjustable height within .005″ accuracy. The height value is displayed, with the ability to store and recall target height settings for multiple jobs. Control output relays interface to the machine height adjustment motors, to initiate automatic and correct height adjustments for the desired job. “S” Stand-Alone and “A” PLC Integrated versions are available, in both 4 and 8 channel packages. The units are simple to install and operate, and provide great time savings over manual methods when job changeover for different products is required.
