4.4.2 Installation of RD4 with pressure t ange »S«
Cylinder mounting
For installation in fluid power cylinders, the standard sensor system
consists of the rod and the mounting flange, and the B type electron-
ics. Install the rod using the fit and seal it off by means of the O-ring
and the supporting ring. Block the rod using a shoulder screw. The
adaptor plate of the separate electronics housing facilitates mounting
on the outside of small cylinders. Advantage of this version: Connec-
tion to the measuring rod is via the bottom of the housing. Thus the
sensor system is fully encapsulated and protected against external dis-
turbances.
Note for cylinder installation:
– The position magnet should not grind on the measuring rod.
– The bore in the piston rod is dependent on the hydraulic pressure
and the piston’s velocity. The minimum drilling should be 13 mm
(0.52 in.).
– Do not exceed the peak pressure.
– Protect the measuring rod against wear.
NOTICE
To fulfill the EMC standards for emission and immunity the
following points are necessary:
• The sensor electronics housing has to be connected to machine
ground.
• The cable between the sensor and the electronics must be
integrated into a metallic housing.
