Description of PDF file:
Ultrasonic fork sensors for web guide and edge control

Description:

UPF-A Series
Ultrasonic fork sensors for web guide and edge control

Common applications

  • for edge position detection and web guidance systems
  • works with transparent and opaque foils
  • works with contaminated air
  • more tolerant of dusty environments than optical barrier sensors


Technical Features
  • Ultrasonic fork barrier with analogue output 0...10V
  • The analogue signal is a function of lateral covering
  • Transmitter and receiver precisely aligned
  • Easy installation with minimal setup time
  • High accuracy and temperature stability
  • Wide detection width of 8 or 13mm
  • High output voltage 10Vdc/8mm or 13mm = 1250mv/mm or 769mV/mm
  • Small plane change error
  • High sampling rate
  • Teach-In


A System
To purchase a complete system, order online one of the 4 UPF-A models listed best fitting your requirement.
Please review the SONARANGE Accesories PDF for factory made cables.
Select the cable required by reading the data sheet and copy and past into [COMMENTS] on your online order.

Properties
The new edge sensors type UPF-A TOR are based on the experience of SNT Sensortechnik AG with ultrasonic through beam sensors. New software algorithms and a unique SONARANGE ultrasonic transducer material allow an accuracy and temperature stability so far only realized with optical systems. But the ultrasonic fork barrier is much less sensitive to dirt and dust compared to optical sensors. Further more transparent materials such as foils can be perfectly handled. The so called plane change error has been minimized to almost zero. Together with the high sampling speed of the sensor this means that fast moving level and fluttering webs are well aligned.
The sensor can ideally be adjusted to the actual air conditions by the help of the teach-in function. Furthermore acoustically transparent materials such as textiles can be measured. With teach-in the signal output can be defined at fully closed as well as at fully open fork. In addition, the output signal can also be inverted via teach-in. The new sensors can be taught by push buttons or through the connector. 3 LED indicate the actual position in 5 steps.
The new larger fork widths are of particular interest if the material web is vertically heavily flattering or if it does not always pass at the same height.

5 advantages of SNT ultrasonic fork sensors
  1. The SNT ultrasonic transducers have a large diameter.
    Result: large measurement range combined with high linearity and resolution.
  2. The all new SONARANGE material of the ultrasonic transducers has a Young’s modulus which is constant up to higher temperatures compared to the past.
    Result: high temperature stability.
  3. The signals are compensated with computed data as well as with a temperature sensor.
    Result: precise operation up to 60°C.
  4. The sensors have the teach-in feature.
    Result: They can be adapted to the actual air condition and the material.
  5. Software and transducers are designed to eliminate the influence of multiple echoes.
    Result: Very small influence of plane change and high measuring speed.
