Before mounting HYDAC Linear Position Transmitter, make sure there are no strong
magnetic and electric interference fields nearby.
Inadmissible interference fields can influence the measuring accuracy. The field strength
may be max. 3 mT in direct proximity of the measuring rod.
The measured values are transferred to the sensor rod via the Position Transmitter's
magnetic field (non-contact measurement). The accuracy of the measured values
among others depends on the symmetry of the magnetic field geometry. Mechanically,
this means that the position sensor must be centrically installed and must be exactly
E
parallel to the axis of the rod.
The position magnet must not rub against the sensor rod.
To provide a proper magnetic field it is further necessary to use a non-ferrous circlip to
fix the magnet.
The bore in the piston rod is dependent on hydraulic pressure and piston velocity etc.
however, it should be at least 13.5 mm. The specified maximum pressure, however, may
not be exceeded.
The sensor is screwed directly into the cylinder base by means of its thread. The
maximum torque of 50 Nm should not be exceeded.
The sealing of the sensor at the cylinder is ensured by an o-ring (15.3 x 2.2) in the
thread run-out groove of the flange or by an o-ring (i.e. 22.4 x 2.65) inside of a groove in
the cylinder base.
