DG50C LASER
DIAMETER GAUGE
Datasheet
The DG50C Laser
Diameter Gauge is primarily used for fast, accurate and contact-less
measurement of the outside diameter of cylindrical or oval objects in the
nominal size range of 1 to 50 mm. The object to be measured may be opaque or
transparent (e.g. glass or plastic) and may move longitudinally (for example on
a drawing line) or transversely (measurement of machined parts or CFL tubes).
The main functions of the equipment are the following:
Measurement: Continuous contact-less
measurement and display of the outside diameter of the object
Classification: Classification
of the object according to the measured diameter and the programmed nominal
diameter and tolerances
Sorting: The equipment provides 230V
50 Hz solid state relay outputs for max 5 sorting actuators. In case of
continuos manufacturing technologies (drawing line) a reference signal is taken
from the cutter.
SPC software:: Statistical
data evaluation and archiving software with chart recorder type display (optional)
PID control output: 4-20
mA analogue PID current signal for controlling the technological process
(optional).
Proportional analogue
output: 4-20
mA analogue output signal proportional to the measured diameter (e.g. for
chart-recorder) (optional).
Further Options:
