Hydraulic ring force transducer
Description
The model F6137 hydraulic ring force transducer, geotechnical version, is available in nominal size NS 82 to 700 kN [157,366 lbf].
This hydraulic force measuring unit can, in conjunction with a measuring or display instrument, display the measured values directly or output them as analogue signals. 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. It is an extremely robust design in line with the requirements of geotechnical engineering.
Hydraulic ring force transducer, model F6137
For maximum availability and ease of maintenance, we offer a connection solution that enables external measured value transducers/displays to be disconnected and replaced under operating conditions without loss of hydraulic fluid.
Applications for hydraulic force measuring units can be found in the field of geotechnology in various fields such as tunnel construction, bridge building and slope stabilisation.
