LMT – Laser strip thickness gauge

Product description

Non-contact measuring using four-point laser distance sensors of a new generation without influence on the refectivity of the surface and with minimum dependence of accurycy on tilted/wavy strip.

The measurement proceeds when the thickness gauge is lead automatically onto the strip by linear module with the option of zig zag scanning. Then the measured data are displayed on the HMI touch panel display or SPC PP-Visual with outputs for Automatic Gauge Control (AGC) system.

Advantages

• use of four-point laser distance sensors of a new generation with automatic alignment control of the optical axis
• any strip colour, surface reflectivity and waviness (tilt up to 2°) have no influence on the declared accuracy of the measurement
• automatic calibration using built-in standard
• air blow of laser sensors against pollution (during measurement)
• optics automatic cover of the laser sensor when the measurement is switched off
• automated strip guidance with scaning mode (profile measurement) as option
• touch screen for easy entry of nominal thickness and limits

The control unit enables

• digital thickness display on 7 “touch screen
• deviation display from the set nominal thickness
• graphical representation of the thickness course
• entering and monitoring lower and upper limits
• control of the gauge guidance onto the strip
• analogue outputs for AGC ± 20 mA (± 10 V, 4 – 20 mA)
• serial data output module PROFINET (PROFIBUS,…)
