Construction
Electrical connection: The electrical connection is made via a M12 plug connection (see Type code).
Housing: Housing containing the processing electronics.
Fastening: We recommend assembling the following BTLs on the mounting thread:
BTL B…: M18×1.5
BTL Z…: 3/4“-16UNF
There is an additional thread at the end of the rod to support large measuring lengths.
Position magnet: Defines the position to be measured on the waveguide. Magnets are available in various models and must be ordered separately (see Accessories).
Measuring length: Defines the travel/length range available. Sensors with measuring lengths from 25 mm to 5000 mm are available.
Function
To determine the position of a plant component, a magnet is connected to the component. Together they are moved along a waveguide located inside the BTL.
An internally generated INIT pulse interacts with the magnetic field of the magnet to generate a torsional wave in the waveguide which propagates at ultrasonic velocity. The component of the torsional wave which arrives at the end of the waveguide is absorbed in the damping zone to prevent reflection. The component of the torsional wave which arrives at the beginning of the waveguide is converted by a coil into an electrical signal. The position of the magnet and thus at the same time that of the plant component is determined from the running time of the shaft.
