MLC750 Laser Triangulation Meters

General Description
The MLC750 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 MLC750 operates at a measuring frequency of 2000
measurements per second. The standard MLC750 operates at a serial output
update frequency of either 1000 or 2000 measurement points per second.
The MLC750 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 MLC750 LTM’s when connected together automatically provide
change in thickness, width or difference values. The MLC750 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 MLC750 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.
