Hydraulics sealing when using a RF sensor in a pressure rod
HD / HL / HP
There are two ways to seal the flange contact surface (Fig. 29):
1. A sealing by using an O-ring (e.g. 22.4 × 2.65 mm (0.88 × 0.1 in.),
25.07 × 2.62 mm (0.99 × 0.1 in.)) in a cylinder end cap groove.
2. A sealing by unsing an O-ring in the undercut.
For threaded flange (¾"-16 UNF-3A) »S«:
O-ring 16.4 × 2.2 mm (0.65 × 0.09 in.)
For threaded flange (M18×1.5-6g) »M«:
O-ring 15.3 × 2.2 mm (0.60 × 0.09 in.)
In this case, a screw hole based on ISO 6149-1 (Fig. 28)
must be provided. See ISO 6149-1 for further information.
Fig. 29: Possibilities of sealing
Note the following points when using a RF-M / -S sensor
or RF-C with pressure rod HD / HL / HP:
• Note the fastening torque of 50 Nm.
• Seat the flange contact surface completely on the cylinder
mounting surface.
• The cylinder manufacturer determines the pressure-resistant
gasket (copper gasket, O-ring, etc.).
• The position magnet should not grind on the sensor rod.
• The piston rod drilling for RF sensors with pressure rod
(rod Ø 12.7 mm (0.5 in.)) is ≥ 16 mm (≥ 0.63 in.).
The borehole depends on the pressure and piston speed.
• Adhere to the information relating to operating pressure.
• Protect the sensor rod against wear.
