Material number:
  • Ultrasonic transducer module
  • Path measurement (resolution 10 µm)
  • Speed measurement (resolution 100 µm/s)
  • 1, 2, 3 and 4 magnetic rod measurements possible
  • DPI/IP protocol supported

This module can be used to determine paths and to calculate speeds at the same time. The ultrasonic transducer rods are connected directly to the RS422 interface. Communication to the transducer rod takes place using start/stop signals. With the DPI/IP protocol, it is also possible, for example, to read operational properties directly from the transducer. During service (when a transducer is being exchanged) the machine can be started again quickly without additional configuration work.

The module is designed for connecting 2 transducer rods with a total of up to 4 paths. That means, for example, that 2 ultrasonic transducers with 2 magnets each or one with 4 magnets can be used. The combination 3/1 is also possible. The module provides 24 VDC as an external supply for the sensor.
