Improper usage
– Operation outside of the technical specifications is not
permitted.
– Operation in areas where there is a danger of explosions is
prohibited.
– The sensor may not be used as a support, handle or step.
– Any use other than the designated use is not permitted.
Operating principle
The DSE-31 sensor works ultrasonically. This ensures the
sensor is ideally suited for optically transparent material webs.
The sensor is totally insensitive to ambient light.
The transmitter generates an ultrasonic field. Depending on how
far away the material web is in the sensor’s field of view, a part
of these ultrasonic waves strikes the receiver. Based on this, the
receiver generates the output signal from which the precise
position of the web edge is determined.
The gap width GW and throat length GL are the characteristic
dimensions of the sensor.
It is possible to operate the sensor with either a supply voltage
of 12V or 24V. The output signal would automatically be
switched over in that case.
– Power supply voltage 12V:
The sensor provides an output signal in the range from 0 to
10mA. Thus the sensor can be connected to all Fife web
guide controllers.
– Power supply voltage 24V:
The sensor provides an output signal in the range from 4 to
20mA. The sensor can therefore also be used directly in
connection with a PLC.
The sensor has a built-in LED display, visible from both sides,
and shows directly on the sensor information about the
operating status like for instance the existence of the supply
voltage, position of the edge of the web inside the field of view
or error messages.
Option
A digital production data acquisition to Fife D-MAXE controller
extends the range of applications for the sensor inside the
digital network environment. Additional sensor data can be
provided to other hardware equipment if the Fife D-MAXE is
linked appropriately to the network.
