Smart line sensor

A sensor device for insertion and for measuring tension within a braided, plaited and/or laid line, the sensor device being shaped as a prolate spheroid and comprising;

• an elongated sensor housing having an outer housing surface and an inner housing surface, the outer housing surface having a substantially elliptic or circular cross sectional area around the longitudinal centre axis of the sensor housing, and at least part of the maximum diameter D of the elongated sensor housing measured in direction perpendicular to a centreline C of the housing's longitudinal direction is constant along at least a portion of the housing's longitudinal length L,
• at least one pressure sensor arranged inside the elongated sensor housing, the at least one pressure sensor being configured to measure, at least indirectly, a pressure exerted on the outer housing surface,
• wherein the elongated sensor housing comprises a middle part and two end parts that are removably connected to the sensor housing by a fixing arrangement such that the removal of at least one end part of the elongated sensor housing allows free access to the internally arranged at least one pressure sensor, and the wherein the fixing arrangement comprises screw threads on the detachable end parts and middle part, configured to engage with each other, thereby allowing the detachable end parts to be screwed on to the middle part.
