WG1C LASER
DIAMETER GAUGE
Datasheet
The WG1C Laser
Diameter Gauge continuously measures the diameter of thin cylindrical
objects, typically wires or fibres.
The laser diffraction wire gauge consists of one or two
measuring heads and an industrial computer based control unit. Distance between
measuring head and the control unit can be up to 100 m.
Working principle:
The work piece to be measured is illuminated by a laser beam
and the resulting diffraction pattern is detected by a CCD sensor array. The
detector signal is digitised and evaluated by the Digital Signal Processor of
the measuring head electronics.
The main functions of the equipment are the following:
Measurement: Continuous contact-less
measurement and display of the outside diameter of the object
Display: Digital
and chart recorder type display of actual and averaged diameters in mm and mg/200 mm units along with Cp and
Cpk statistical data
Software:: Statistical
data evaluation and archiving software for handling the data of measured spools
Analogue output: 4-20
mA analogue output signal proportional to the measured diameter (e.g. for
chart-recorder) (optional).
Special versions:
·
XY measuring head for measuring oval objects
·
Multiple Measuring Heads with one Control Unit
·
Custom designs and individual software development
·
Interface to spooling/drawing unit for automatic start and stop of spool
evaluation
Typical applications:
·
Measurement of tungsten an molybdenum wires
·
Measurement of copper wires with and without insulating layer
