Read this manual before installing and operating the Micropul Trans-ducer.1.1
Proper application
The BTL5 Micropul transducer is intended to be installed in a ma-chine or system. Together with a controller (PLC) it compris a posi-tion measuring system and may only be ud for this purpo.Unauthorized modifications and non-permitted usage will result in the loss of warranty and liab

ducer system. In particular, steps must be taken to ensure that should the transducer system become de-fective no hazards to persons or property can result. This includes the installation of additional safety limit switches, emergency shutoff switches and maintaining the per-missible ambient conditions.1.4
Scope
This guide applies to the model BTL5-A/C/A/ Micropul transducer.

Function
The transducer contains a tubular waveguide enclod by an outer stainless steel rod. A magnet at-tached to the moving member of the machine or to the cylinder pis-ton is moved over the rod and its position constantly updated.The magnet defines the measured position on the waveguide. An inter-nally generated INIT pul interacts with the magnetic field of the mag-
net to generate a magnetostrictive torsional wave in the waveguide which propagates at ultrasonic speed.
The torsional wave arriving at the end of the waveguide is absorbed in the damping zone. The wave arriv-ing at the beginning of the wave-guide creates an electrical signal in the coil surrounding the waveguide.The propagation time of the wave is ud to derive the position. Depend-ing on the version the corresponding value is output as a voltage or a cur-rent either with rising or falling char-acteristic. This process takes place with measuring high precision and repeatability within the stroke range defined as nominal stroke length.At the rod end is a damping zone,within which no reliable signal is available, but which may be entered by the magnet.
The electrical connection between the transducer, the processor/con-troller and the power supply is via a cable, which depending on the ver-sion is either fixed or connected using a female connector.

Available stroke lengths and magnets
To ensure flexible application, nomi-nal transducer stroke lengths of from 50 to 4000 mm and various types of magnets are available.Magnets therefore need to be or-dered parately.

The smallest permissible distance between magnet ring and rod mounting surface is shown in Fig. 3-2.
if you want meThe transducer has either a
M18×1.5 thread or a 3/4"-16UNF thread for mounting. The aling is carried out with the O-ring supplied at the flange facing.
Important Installation Notes:The contact surface of the trans-ducer must be completely con-tacted by the mounting surface.The O-ring supplied must make a perfect pressure al, i.e. the bevel for the O-ring must be configured exactly as shown in Fig. 3-3.To achieve cure mounting, u the proper nut for the mounting thread. When tightening the nut, do cylinder rod should be at least 13 mm.
When attaching the transducer to magnetizable materials, appropriate measures must be taken to protect against magnetic disturbances,➥ Fig. 3-1.
