Capacitive Sensor Module

Module MZ002 is developed for application in laser head VF001, but it can be applied in any laser head. Measurement is based on standard capacitive principle on the basis of high-frequency bridge. Implementation of the module in the form of a small-sized processor board of 40×20 mm in size installed directly on the head near the nozzle distinguishes it from other counterparts. Circuit solutions ensure high sensitivity, interference protection and possibility to work with nozzles of any geometry, including super narrow ones.

The module performs internal conversion of sensor characteristic into linear distance, check of contact and errors and measurement of nozzle temperature. Recommended installation of the module is shown in Figure.

The module supports several connection interfaces:

wire
optical on the basis of open optical channels for quick change of tip
- with use of duplex digital channel and interface board MZ003
- with transfer of distance in the form of pulse rate

Fiber Laser Control Modules

Fibre laser control modules of ©InSoft Laboratory simplify connection of CNC systems of machines or fibre laser stations series ЛС, reduce the quantity of cabling and ensure operation of laser in pulse-periodic modes.

The modules receive all required check signals from laser and generate all required control signals, including generation of pulse trains. External control is via CAN protocol; if needed modules are equipped with CAN-RS232/RS485 converters. The module is installed in hermetic case directly on fiber laser control connector series ЛС. External connections are minimized (power supply 24 V, CAN line, optionally: input and output interlock circuit).
