General Description
The MLM 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 center or is outside
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.
All standard MLM models operate at a measuring
frequency of 2000 measurements per second. All standard MLM models
operate at a serial output update frequency of either 1000 or 2000
measurement points per second.
All standard MLM models have a
programming/select functionality. Group mode is the main feature. In
Group Mode a running average is calculated over a user specified number
of measuring points. The user also programs the sensor to disregard a
number of, usually all, bad (zero) measuring points before calculating
the average value. The average values are calculated at full measuring
frequency and are used for converting the analog signals. Several median
filters and Level Mode are other available features.
Two identical
MLM LTM’s when connected together automatically provide change in
thickness, width or difference values. The MLC standard 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.
These LTM’s
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.
