ONP1-A/WPG-A SERIES – CORRECT USE OF THE PCUR034 FLOATING PCUR039/PCUR202
12
100�5
Under standard conditions (Fig� 1), the PCUR039/PCUR202 cursor must be installed on a support made of non-magne-
tic material (such as brass, aluminium, or AISI316 stainless steel)�
The installation kit, consisting of two screws, two nuts, and two washers (all made of brass), is included in the package�
The cursor (Fig� 2) must be installed with maximum attention to horizontal alignment with the transducer axis (maximum
tolerance is ± 2 mm), as well as to the distance from the transducer surface from 2 to 5 mm�
If there is no alternative to a magnetic sup-
port, itʼs necessary to prevent the support
from changing the magnetic field generated
by the cursor, because this could cause pro-
blems with the correct measurement of the
cursor position�
For this reason, a non-magnetic spacer must
be added between the cursor and the magne-
tic support (Fig� 3 - Sol� 1)�
The recommended spacer thickness is 15 mm�
If the application does not permit the installa-
tion of a non-magnetic spacer, itʼs possible to
install the cursor directly on the magnetic support, being careful not to let the support make direct contact with the
part of the cursor containing the magnet (Fig� 3 - Sol� 2)�
INSTRUCTIONS FOR ELECTRICAL INSTALLATION OF MAGNETOSTRICTIVE TRANSDUCERS
The magnetostrictive transducers conform to the following directives:
- Electromagnetic Compatibility EMC 2014/30/EU
- RoHS 2011/65/EU
For a correct electrical installation of the transducers, refer to the "Manual for Electrical Installation of Magnetostrictives�"
The manual and certificates of conformity can be downloaded from the website www�gefran�com�
