PlasmaSensOut THC controller

PlasmaSensOut is a universal torch height controller (THC) for precise plasma cutting.

PlasmaSensOut THC controller, thanks to an optical fiber connection, PlasmaSensOut and PlasmaSens torch height sensor (including in a package) forms a complete and reliable torch height controller. Thanks to an optical connection it’s fully electrically (galvanic) isolated from high voltage plasma cutter’s equipment and also safe to use. PlasmaSensOut has standard programmable ARC_OK, UP, and DOWN signals. Generally, it is compatible with most CNC controller boards on the market.

The user interface is simple and user-friendly. On the left, there are 3 LED diodes to signalize the state of the outputs. Next on the right side is also an LED display. It has great readability also in a high luminosity environment. In the default state, it shows temporally arc voltage. However, menus appear on the LED display during settings.
Under the LED display there are 3 buttons. Hence they allow quick and efficient moving through the menu.   Users can set the following THC parameters: reference voltage, hysteresis (non-active range around reference height), delay time, and anti-dive limit voltage. Moreover, all parameters are adjustable during operation.

It doesn’t need any drivers or special software. Even more, it is compatible with most CNC software and hardware which accepts OK, Up and Down signals.
