General Description
The MLC 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 MLC models operate at a measuring frequency of 2000
measurements per second. All standard MLC models operate at a serial
output update frequency of either 1000 or 2000 measurement points per
second.
All standard MLC 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 MLC 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.
Optional -S5 models operate at a 5KHz measuring frequency and at a 1kHz,
2½kHz or 5kHz update frequency ,and have a serial interface baud rate of
38400,115200 or 230400. Optional -S10 models operate at a 10kHz
measuring frequency and at a 1KHz, 2½ kHz, 5kHz or 10kHz update
frequency, and have 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.
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. |
