4 Together with a controller (PLC) or a processor(BTA) it comprises a position measuring system and may only beused for this modifications and non-permitted usage will result inthe loss of warranty and liability Qualified personnelThis guide is intended for specialized personnel who will perform theinstallation and setup of the Use and inspectionThe relevant safety regulations must be followed when using thetransducer system. In particular, steps must be taken to ensure thatshould the transducer system become defective, no hazards topersons or property can result. This includes the installation ofadditional safety limit switches, emergency shutoff switches andmaintaining the permissible ambient ScopeThis guide applies to the model BTL5-A/C/ overview of the variousmodels can be found in section 6 Versions (indicated on part label)on page : For special versions,which are indicated by an -SU_ _ _ designation in the partnumber, other technical datamay apply (affecting calibra-tion, wiring, dimensions etc.)

A magnetattached to the moving memberof the machine is moved acrossthe top of the Housing and itsposition constantly magnet defines themeasured position on thewaveguide.

7 An internallygenerated INIT pulse interactswith the magnetic field of themagnet to generate a magneto-strictive torsional wave in thewaveguide which propagates atultrasonic torsional wave arriving atthe end of the waveguide isabsorbed in the damping wave arriving at the beginningof the waveguide creates anelectrical signal in the coilsurrounding the waveguide. Thepropagation time of the wave isused to derive the on the version thecorresponding value is output as avoltage or a current either withrising or falling characteristic. Thisprocess takes place with highprecision and repeatability withinthe stroke range defined asnominal stroke both ends of the nominalstroke length is an area whichprovides an unreliable signal, butwhich may be electrical connection betweenthe transducer, the processor/controller and the power supply isvia a cable, which depending onthe version is either fixed orconnected using afemale for installing theMicropulse transducer and for themagnets and control arm arefound on pages 4 and Available stroke lengthsand magnetsTo provide for optimum fit in anyapplication.

8 A wide range ofstroke lengths, magnets andmounting hardware is , control arms andmounting brackets must beordered inside front cover for availablestroke Transducer installationAny orientation is permitted. Themounting brackets and cylinderhead screws allow the transducerto be mounted on a flat machinesurface. These should be evenlyspaced (Figs. 3-1 and 3-5).The recommended spacing forlong transducers and extremeconditions ( strong shock orvibration): A = 80 mm; spacingbetween the individual bracketsB = 250 isolation bushings are used toelectrically insulate the transducerfrom the machine (Fig.)
