3. Functional Principle, Technical Data
3.1 Short Description
3.1.1 Measuring Principle
The scanCONTROL 29xx sensor operates according to the principle of optical triangulation (light intersection
method):
- A laser line is projected onto the target surface via a linear optical system.
- The diffusely reflected light from the laser line is replicated on a sensor array by a high quality optical sys-
tem and evaluated in two dimensions.
The laser line triangulation corresponds in principle to the triangulation of a laser point. However, during the
measurement a row of lines are simultaneously illuminated by the laser line. Apart from the distance infor-
mation (Z-axis), the exact position of each point on the laser line (X-axis) is also detected and output by the
system.
3.1.2 System Setup
The scanCONTROL 29xx sensor is a compact sensor with an integrated controller. All necessary integral
parts are combined in one housing.
3.1.3 Special Performance Features
- scanCONTROL 29xx is characterized by its compact design and high speed along with high measuring
accuracy. A special line-scanning optical system ensures uniform exposure of the measuring field.
- The sensor array is arranged in the sensor head according to the Scheimpflug condition which enables
uniform image focusing over the whole depth of the measuring range (Z-axis).
- The scanCONTROL 2910/2960 series with integrated profile evaluation works even without a PC in con-
junction with saved configurations. The sensor performs the profile measurement internally and calculates
default measured values such as angle or edge position.
Besides measurement value output via Ethernet (Modbus TCP protocol, UDP protocol) and RS422 (Mod-
bus RTU protocol or ASCII format), additional switching signals (results of the determination of limit values)
and analog measurement values can be output. This is done by an optional scanCONTROL Output Unit,
which transforms the determined measurement signals in switching and analog signals for further process-
ing in a PLC.
- scanCONTROL Gateway allows for scanCONTROL SMART sensors to be integrated into various fieldbus
systems (PROFINET, EtherNet/IP, EtherCAT).
