MLC20.5 Laser Triangulation Meters

General Description
The MLC20.5 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.
The standard MLC20.5 operates at a measuring frequency of 2000
measurements per second. The standard MLC20.5 operates at a serial
output update frequency of either 1000 or 2000 measurement points per
second.
The MLC20.5 has
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 MLC20.5 LTM’s when connected together automatically
provide change in thickness, width or difference values. The MLC20.5
operates at a 2kHz measuring frequency and at a 1kHz or 2kHz update
frequency, and has a serial interface baud rate of 38400 or 115200. The
optional -S5 model operates at a a 5KHz measuring frequency and at a
1kHz, 2½kHz or 5kHz update frequency ,and has a serial interface baud
rate of 38400,115200 or 230400. The optional -S10 models operate at a
10kHz measuring frequency and at a 1KHz, 2½ kHz, 5kHz or 10kHz update
frequency, and has a serial interface baud rate of 38400, 115200, 230400
or 460800. To use the baud rates of 230400 and 460800 the -R4
RS422/RS485 serial interface option is required.
The MLC20.5 LTM has 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.
