The Sensor THC is a full featured torch height control
system specifically designed to integrate with Hypertherm
Automation’s shape cutting controls. The Sensor THC
incorporates the latest advancements in system integration and
hardware reliability. With integrated SoftMotion and closed
loop servo control, the Sensor THC simply outperforms the
competition.
The result is an easy to use height control that
can significantly increase the productivity and profitability of
your shape cutting operation.
Installation and setup features
