RUN-OUT INSPECTION OF WHEEL CASTING
Objective: Prior to machining, inspect a wheel casting to ensure
that six critical dimensions are within tolerance.
Sensor:
L-GAGE model LG5A65PU
Operation: Wheel castings slide into a rotating fixture beneath six
stationary L-GAGE sensors. Each L-GAGE is positioned
so that a nominal casting is at the center of the sensor’s
measuring window. The 0 to 10V dc outputs of all six
sensors are fed into a PLC, which records maximum runout.
The LG5A, with its wide beam diameter, was selected for
best output stability on a rough casting surface. The L-GAGE
non-contact sensor eliminates frequent sensor replacement
and recalibration.
THICKNESS MEASUREMENT OF PLYWOOD
Objective: Measure thickness at three points across the width
of a sheet of plywood
Sensor:
L-GAGE model LG10A65NU
Operation: Three pairs of L-GAGE sensors are set up across a sheet
of laminate. Thickness at each location is determined
by subtracting the distance from each sensor to the
plywood from the distance between the pair of sensors:
t = F - (A+ B), where A is the top distance, B is the
bottom distance, and F is the fixed distance between the
sensors in each pair.

WOOD PROFILING
Objective:
Profile wood moldings; inspect milled dimensions.
Sensor:
L-GAGE model LG10A65NU
Operation: The L-GAGE, with a 100 mm standoff distance and
a 50 mm measuring window, can accurately profile
a wide variety of wooden moldings in milling
applications. Not only is the L-GAGE fast and
accurate, it is also very tolerant of changing wood
colors. For example, changing from dark walnut to
light ash requires no change in sensor configuration.
