General Description

The MLS Laser Triangulation Meter (LTM) is a compact unit with integrated optics and signal processor for precise measurement of distance or product thickness and width. A focused laser spot is illuminated on the object and the image distance determined by internal CCD array. LED’s indicate when the object is at the center or is outside of the measuring range. Installation software is provided for connection to a PC and to display measured values. Measurement of data is via RS232 and analog outputs.

The MLS models operate at a measuring and serial output update frequencies of 1,000 measurements per second. All MLS models have programming/select functionality. The main feature is Group Mode. In Group Mode a running average is calculated over a user specified number of measuring points. The user also programs the meter to disregard a number of, usually all (if there are any zero measurement results), before calculating the average value. The average values are calculated at full measuring frequency and are used for converting the analog signals.

Two identical MLS LTM’s when connected together automatically provide change in thickness, width or difference values. The MLS Standard models operate at a 1kHz measuring & update frequency and have a serial interface baud rate of 38400. Optional -S2 models operate at a 2kHz measuring frequency and at a 1kHz or 2kHz update frequency, and have a serial interface baud rate of 38400 or 115200. Optional -S5 models operate at a 5kHz measuring frequency, and at a 1kHz, 2½kHz or 5 kHz update frequency and have a serial interface baud rate of 38400, 115200 or 230400. The baud rate of 230400 requires option -R4 RS422/RS485 serial Interface.

The MLS laser triangulation meters have a broad range of usage for measurement off surfaces where other devices fail. Ideal for measuring off wood, plastic, glass, rubber, paper, foam, textiles, food product, cold, hot or molten metals as well as various liquids.
