Sensor brochure for food industry
Balluff introduces brochure on sensors for the food and packaging industry.
Balluff has introduced a brochure called "Sensors for food and packaging industry" This full colour brochure features various products for food process and packaging machinery automation and highlights Balluff's approach to problem solving from detecting clear film to unusual shaped objects

Linear transducers now have integrated Profibus-DP
Micropulse magnetostrictive linear transducers from Balluff-MultiSwitch are now available with integrated Profibus-DP, and automatic baud rate detection by the transducer assures trouble-free startup
Ultrasonics protect products in conveyor system
The Microsonic MIC range of ultrasonic sensors have been used by Ace Assembly Systems to solve the problem of product damage when transferring from their Platen System conveyor to packing cases
Included is the BLG 1 light grid, which allows detection and measurement of objects, even over large areas.
The photoelectric light grid is for any area of automation technology but especially suits the food and packaging industry.
Working on the basic principle of a through-beam sensor, infra-red LEDs are used as the light source.

Proximity sensor covers four times the distance
Featured on the Balluff stand at Mach 2002 will be the latest innovations in sensing, safety and control systems for the machine tool and automotive industries.
Among the key applications are detecting, counting and measuring various objects, for example when packages need to be selected or checked on a conveyor.
The height or width of objects can be determined and used as the basis for a decision with respect to further processing.
The light grid can detect objects as small as 4mm in diameter.
Two outputs are available.
The analogue output provides a voltage signal proportional to the number of interrupted beams.
This voltage signal can be directly processed in the controller.
A single light grid - consisting of emitter and receiver - allows numerous objects to be detected.
The digital output always becomes active when at least one light beam is interrupted.
This output is for counting objects, and also enables planar presence monitoring.
The product can be installed and operated with no special technical expertise.
Installation is simple, and alignment non critical.
The integrated power and diagnostic indicators make startup and troubleshooting easier.
The housing is made of anodised aluminum and is suitable for harsh environments.
The light grids are available with controlled heights of 100, 150 and 300mm and ranges of 850 and 2100mm.
Also covered is the BFS 27K colour sensors, measuring devices suitable for detecting dark colours.
Small colour differences can be detected, for example in quality control of textiles, leather or plastics, such as in the production of packaging materials.
Colour sensors are widely used in the fields of robotics, automation and quality assurance, as well as in production processes.
Quality assurance checking, selection of parts according to colour or sensing cable conductor wire colours are some of the tasks it can handle.
Problem solver pages provide a quick overview of techniques such as cap detection, clear object and film detection, unusual object detection, height and level control, product quality control and distance and thickness measurement.
Ideas are included for reducing the risk of mechanical damage to sensors and therefore reducing down-time and sensor cost outlay.
