MAGNET SPECIFICATION
Vivace offers the following magnet options for the valve positioner:
ROTATIVE
Option
0
on Ordering Code
Used on rotative systems, it has a standard diameter with measurement from 0º to 120º (minimum span of 5º between
inferior and superior points).
Figure 2.16 – Dimension and assembly of rotative magnet.
LINEAR
Linear 30
Option
1
on Ordering Code
Used on linear systems up to 30 mm, with measurement from 0 to 30 mm (minimum span of 10 mm between inferior
and superior points).
Linear 70
Option
2
on Ordering Code
Used on linear systems of 30 mm to 70 mm, with measurement from 0 to 70 mm (minimum span of 30 mm between
inferior and superior points).
WARNING
Correct magnet dimensioning is a primordial for perfect performance of position measurement, allowing
sensor to achieve all system length with the highest magnetic field variation possible.
User must consider installation environment, type of movement (rotative or linear) and amplitude (length),
in addition to mounting bracket to be used, among other parameters.
ATENÇÃO
A extensão total do curso da válvula deve estar contida dentro das marcações de curso do ímã para o
correto funcionamento do posicionador.
