1.
Safety precautions
Use supply voltage and interfaces indicated in the sensor specifications.
In connection/disconnection of cables, the micrometer power must be switched
off.
Do not use micrometers in locations close to powerful light sources.
To obtain stable results, wait about 20 minutes after micrometer activation to
achieve uniform micrometer warm-up.
Elements of the system should be grounded and join the grounding bus
through a separate line.
2.
Electromagnetic compatibility
The system have been developed for use in industry and meet the requirements
of the following standards:
EN 55022:2006 Information Technology Equipment. Radio disturbance charac-
teristics. Limits and methods of measurement.
EN 61000-6-2:2005 Electromagnetic compatibility (EMC). Generic standards.
Immunity for industrial environments.
EN 61326-1:2006 Electrical Equipment for Measurement, Control, and Labora-
tory Use. EMC Requirements. General requirements.
3.
Laser safety
The micrometers make use LED or c.w. 660 nm wavelength semiconductor la-
ser. Maximum laser output power is <0,2 mW. The micrometers belong to the 1 laser
safety class. The following warning label is placed on the laser body.
The following safety measures should be taken while operating the sensor:
Avoid staring into the laser beam during a prolonged time period;
Do not disassemble the micrometer.
4.
General information
The system is designed to control the geometrical parameters (width and thick-
ness) and the temperature of the tapes, in particular, packing straps during the manufac-
turing process.
The system is applied in the mass production. Production line is the place of in-
stallation.
Technical characteristics of the system can be changed for a specific task.
5.
Structure and operating principle
Optical micrometers are used to control the geometrical parameters of the tapes.
The principle of width measurement is shown in the Fig.1
