Sheet Metal Thickness Sensors

12.1. DSP, DSPW and BDWF for Single Surface
Contact Measurement
12.1.1. Mounting
The sensor is frequently installed into an appropriately de-
signed suction cup on the grabber.
The vacuum gripper lifts the workpiece from the stack, bring-
ing it near the sensor. Just before the workpiece touches the
sensor, the proximity switch recognises the sheet metal and
initiates the measurement.
In the case of ferrous metals, the workpiece is held onto the
sensor during the brief measuring time (≤ 110 ms). Instead of
having a sensor in the vacuum gripper, it can be mounted in
a measuring station. In such case, however, the workpieces
must remain motionless relative to the sensor during meas-
urement. Mounting the sensor directly under and flush with
the surface supporting the workpiece avoids accumulation of
dirt and filings around the sensor (avoid air gap between
sensor and workpiece).
A spring mounted sensor is a suitable expedient if work-
pieces which are not flat and/or are very stiff (more than 1.5
mm thick) are to be processed. The workpieces must be
large enough to completely cover the sensing face of the
sensor during measurement.
