L20

Three pairs of sensors can be connected to the three-channel processing unit. The measurement is simultaneously possible for all three channels. The device also supports the connection of the sensor type + LAAS. These sensors feature a laser beam monitoring for an increased process reliability. New: Thickness Gauging System L20E

Datasheet L20

Dual Head Double Sheet Control System for
Metals and non metal material.

Laser based function principle;

Thickness Control from 0.3 to 15 mm (.012 to .590 in)

Applications

Flexible Manufacturing Systems in the sheet processing industry require an automated reliable monitoring in order to protect stamping presses and other sheet processing equipment against damage caused by multiple sheet feeding.

The Double Sheet Control System R1000 L20 was specifically developed for this technical environment. Particular attention was given to maintenance free operation and self monitoring features of the measuring system.

New functions have been added to ensure less failure and down time during operation. Thus the investment is recovered within a few months of operation with full process reliability.

Features

Suitable for magnetic feeder systems without velocity limitations
Connection of up to three pairs of sensors at one unit (3-channel-version)
Absolute measuring method
Digital display of sheet thickness and operational parameters
Monitoring of over-gauge and under-gauge limits
Monitoring of laser function and sensor gaps
Integrated fieldbus interface with process and parameter interface
