9.1.2 Block diagram SND40 with combination sensor
A system consists of a control unit SND40, a sensor and a sensor cable. The block diagram
exemplarily shows a system with leakage flux module (4) and eddy current module (6). To it a
combination sensor (7) for round materials is attached.

KM: The communication module is
the interface to the operator and
stores the system and program files.
Power: The power supply module
supplies all internal modules and the
sensors with electrical energy.
PM: The processor module takes over
the detection and positioning of the
welding seam and controls the PLC
interface.
MF: The leakage flux module is the
"front end" electronics to the Hall
sensor and supplies the magnetizing
current for the leakage flux and
combination sensors. In addition a
sensor (check signal) with current exit
(0... +/-20mA) can be attached. This
module is only present with SND40
devices with the
numbers... MF... in the designation.

current sensor. This module is only
