Capacitive height sensor for laser cutting, output 0~10V analog quantity represents the corresponding calibration height, suitable for PA8000, Beckhoff system, etc., compatible with Precitec EG8030 height adjuster.
CHC-1000S capacitance height controller(Hereinafter referred to as CHC-1000S). In the laser cutting process, the distance between the nozzle and the surface of the workpiece is not constant due to factors such as uneven workpiece and cutting high-pressure air jet, which will have a negative effect on the cutting effect and may even crash the nozzle. CHC-1000S can keep the distance between the nozzle and the workpiece surface constant during high-speed laser cutting, protect the nozzle from colliding with the workpiece, and greatly improve the cutting effect. The capacitance sensor on the cutting head can detect the distance from the nozzle to the surface of the workpiece, and send it to the adjustment box for processing through the preamplifier. The output signal is sent to the servo controller to control the Z axis.
CHC-1000S can be used as a controller to output the voltage, or as a distance measurement system to output the distance signal, it depends on the selected mode: sensor control mode or distance measurement system mode.
