TheMicropulseTransducercontainsthewaveguidewhichisprotectedbyanouterstainlesssteeltube(rod)

The Micropulse Transducer contains the waveguide which is protected by an outer stainless steel tube (rod). A magnet is moved along the waveguide. This magnet is connected to the system part whose position is to be determined.
The magnet defines the position to be measured on the waveguide.
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 speed.
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 travel time of the wave is used to calculate the position. Depending on the version, this information is made available as a voltage or current output with a rising or falling gradi

BTL7...A/B/Y/Z(8)... transducer, construction and function
Construction3.1
Electrical connection: The electrical connection is made via a cable or a connector (see Ordering code on page 25).
BTL housing: Aluminum housing containing the processing electronics.
Mounting thread: The transducers with Ø 10.2 mm have an additional thread at the end of the rod to support larger nominal lengths. We recommend assembling this transducer on the mounting thread:
BTL7-…-A/B: M18×1.5––
BTL7-…-Y/Z: 3/4"-16UNF––
Magnet: Defines the position to be measured on the waveguide. Magnets are available in various models and must be ordered separately (see accessories on page 23).
B: 30-1 mm
Z: 2"-0.04"
