Descripton
The inductive speed sensor ID is used for contact-free measu-
rement of the rotary speeds at the Axial piston pump of type
A4VTG (see RE 92012) and Axial piston motors of Rexroth (as
to table page 2).
The Hall speed sensor Hdd (as to RE 95135) should, however,
be applied in new projects (different installation conditions).
The sensor is installed in a special mounting hole in the
housing of the axial piston pump/motor and detects the speed
on an internal gear wheel or comparable component made of
ferromagnetic material.
The frequency f of the generated sensor output voltage is a
function of the number of teeth z on the circumference of the
gear wheel and of the rotary speed n of the Axial piston unit:
f =
z • n f in sec
-1
60 n in min
-1
Based on the frequency the speed of the axial piston unit can
be calculated with the BODAS controllers RC (RE 95200).
The speed sensor ID is simply screwed firmly into the housing
of the axial piston unit and requires no further adjustment. In
the axial piston motor, the precise measuring distance is set by
a special spacer ring, which has an integral O-ring to ensure a
safe seal against the housing pressure.
