F6148 Hydraulic Ring Force Transducer

A cylinder-piston combination, filled with hydraulic medium, in a steel version with surface coating or in stainless steel version (option), forms the basis of the anchor force measuring system. For nominal size NS 146, the force-bearing surface of the piston is 146 mm2 and the rated displacement of the piston does not exceed 0.5 mm.

Applications

Special features

Measuring ranges 0 … 150 kN to 0 … 1,500 kN
Relative linearity error ±1.0 % with analogue pressure gauge, ±0.5 % with digital pressure gauge or pressure sensor
Piston stroke ≤ 0.5 mm
Operates without supply voltage
Case and piston made of galvanised steel

Description

The model F6148 hydraulic ring force transducer (geotechnical version) is available in nominal size NS 146 up to 1,500 kN.

Both the mechanical and the electrical version are optionally available with directly attached measured value pick-up/display. There is also an external version. It is an extremely robust design.

With these hydraulic force measuring units, clamping forces are detected at the anchor head in a simple way and brought directly to the display. The force measuring units are used for continuous monitoring of anchors and other bracing rods/cables.
