Fife M431027 Web Edge Sensor

FIFE DSE-41
DIGITAL ULTRASONIC SENSOR
Because of its compact size and temperature stability, the digital ultrasonic sensor DSE-41 is the ideal solution for
guiding clear films and most opaque webs.
The DSE - 41 uses ultrasonic waves to measure the lateral position of the web material. The proportional band allows
significant guide point adjustment. The DSE - 41 is often used in pairs for centre guiding when web width variations are
limited. The DSE - 41 is insensitive to ambient light and it’s used to guide most of the opaque material and clear films.
When used with acoustically permeable material a calibration between the sensor and the material is necessary.
It is possible to operate the DSE - 41 with either a supply voltage of 12 V or 24 V. The output signal
would automatically be switched over in that case.
In 12 V supply mode the sensor provides an output signal from 0 to 10 mA and can be connected to all
available Fife web guide processors.
In 24 V supply mode the sensor supplies an output signal between 4 and 20 mA and can be easily
connected to a PLC as well.
The DSE - 41 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.
An optional digital production data acquisition to Fife D-MAXE controller extends the range of
applications for the DSE - 41 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.
