torch height sensor

Comparing to old CHC-200D, CHC-200E has new features as follow,

1, Increased more indicators to shows different states of THC.

2, Output of collision-alarm, which is optical isolation output from THC, can be sent to CNC’s Alarm input to freeze machine’s move. This signal is effective on both manual/auto mode. The max output is 200mA, capable to drive most relays.

3, Anti-collision function. On manual/auto mode, when metal or low-conductive item like hand touches sensor ring, THC would send out collision signal and lift torch up until no collision exist.

4, When HF cable is disconnected or weakly connected, it would be indicated on the disconnection indicator. So after installation of HF cable, just shake the HF cable, the connection will be showed by the indicator.

5, Sensitive and Accuracy is increased 100%.

6, CHC200E uses digital logic control circuit for logic control, greatly improved anti-interference performance.

History of HYD Torch height controller

1996made first capacitive torch height controller (Analog circuit);

1998made first arc voltage torch height controller (Analog circuit);

2003designed SCM based PTHC (Ontime);

2004set up HYD.CNC Tech Co, stopped developing of immature Ontime THC, and returned to Analog Circuit design, developed XPTHC-100 and CHC-200D, and simplified XPTHC-II

2006made XPTHC-100II, CHC-200DII, and XPTHC-III;

2008made capacitive CHC-300 for laser cutting;

2009started to co-design THC with Messer China, and developed XPTHC-200; Koike started to use CHC-200DII

2010made XPTHC-100III

2011Made new generation THC, XPTHC-300, and CHC-200E.

2012designed DC version cap THC for Zinser, and new laser CHC-300.
