• The transducer must be installed away from sources of magnetic fields, both static and 50 Hz (electric motors, solenoids,
etc�)�
• The transducer connection cable must be wired separately from power cables and/or solenoid controls, drives, or remote
switches�
• The line used for power supply must be dedicated to the transducers or must be drawn directly from the power terminals
and as near as possible�
• When choosing a cursor for the ONP1-A/WPG-A profile magnetostrictive transducer, remember that the transducerʼs
cursor is a magnet� Therefore, if there are iron filings or small magnetic metal fragments in proximity of the transducer,
avoid the use of sliding cursors, as there would be a risk of material accumulation on the cursor, creating problems for
sliding�
Use a floating cursor instead�
ONP1-A/WPG-A SERIES – CORRECT USE OF INSTALLATION BRACKETS
Brackets (2 brackets for every kit)
Steel bracket, interaxis 42�5mm
Steel bracket, interaxis 50mm
Use PKIT59x brackets (to be ordered separately) to correctly install the ONP1-A/WPG-A magnetostrictive transducer�
Choose the best model based on the material, on the attachment holes interaxis and on the dimension of the screws
included in the package� Each package has two brackets� We recommend to install one bracket every 250-300 mm�
To guarantee the correct electrical insulation of the transducer from the machine, always assemble the brackets using the
plastic whashers provided in the package as shownin the fig� a and fig� b�
To prevent damages to the isolating bushes and to the brackets, tighten the fastening screws with a maximum torque of
1�1 Nm�
