Operation in applications with increased ESD requirements
Using the included metal screw caps, the sensor can be used in applications with increased
ESD requirements up to 30 kV (ESD = electrostatic discharge). The metal coupling nuts are
screwed on the front of the transmitter and receiver. The installation of the transmitter and receiver must ensure a large area electrical connection to the machine earth.

Description of sensor functions
The ultrasonic double sheet monitor for splice detection can be used in all applications,
where an automatic detection of glue dots, splices, bondings or the absence of base material is required, to protect machines or to evade waste production. The double-sheet
monitor is based on the ultrasonic through-beam principle. The following can be detected:
- No base material, i.e. air,
- glue dots, splices, bondings
A microprocessor system evaluates the signals. The appropriate switch outputs are set
as a result of the evaluation. Changes in ambient conditions such as temperature and
humidity are compensated for automatically. The interface electronics is integrated into
a compact M18 metal housing together with a sensor head.
Electrical connection
The sensor is equipped with 6 connecting wires. The functionality of the connections is
described in the following table. The teach input (PK) is used to teach the sensor.
