The KR34 ring force sensors are suitable for measuring prestressing forces in cables, e.g., for applications measuring force in prestressed concrete.
The contact surfaces are ground flat and parallel, and the material 1.2379 (X153CrMoV12) is hardened to HRC 62-64. The sensor is characterized by a very small outer diameter. Therefore, a Kevlar-sheathed flat ribbon cable is used as the connecting cable, which is tangentially bonded to the sensor body and covered with heat-shrink tubing. The M12 circular connector allows the connecting cable to be extended to the desired length using a standard sensor-actuator cable from the "M12" series.
The GSV-6T3 M12/CAN three-channel measuring amplifiers, which connect via M12 sockets, are particularly suitable for connection. By connecting multiple measuring amplifiers in a line configuration via the CAN bus, a cost-effective and robust multi-channel measuring system for the construction site can be implemented. Software such as GSVmulti or GSVgrid is used for data acquisition.
