Patent ID: 8474329

Claim:
A sensor device for measuring an axial force in the longitudinal pipe direction of a pipe and at least one torque, comprising: a measuring element having an adaptor connection; a pipe extension piece configured to connect the adaptor connection to the pipe, the pipe extension piece being insertable into the pipe; an alignment adaptor coupled to the pipe with the pipe extension; a plurality of strain gauges arranged at DMS measuring points in a sensor region between the adaptor connection and an end of the pipe extension piece, which is remote from the adaptor connection; wherein the axial force and the torque are introduced into the alignment adaptor with the measuring element and are measured with the plurality of strain gauges; wherein the pipe extension piece with the sensor region has a tubular design, the sensor region extends from the adaptor connection to the end of the pipe extension piece and has a smaller external diameter than the end of the pipe extension piece, an end of the pipe faces the adaptor connection and overtops the end of the pipe extension piece toward the adaptor connection and is decoupled in terms of force from the sensor region and from the adaptor connection; wherein the DMS measuring points include eight DMS measuring points arranged on the perimeter of the sensor region in a radial plane with a respective 22.5° offset from four alignment screws having a 90° offset.
