    Abstract: A strain gauge sensor system and method for measuring the strain in a member, such as a fiber rope, has a sensor target assembly having a plurality of magnets carried spaced apart by individual gauge lengths along the member. Position and trigger sensor devices are configured spaced apart along side a desired path of travel of the member. When the member is fed along the desired path of travel, the trigger sensor device, in response to magnetically sensing a passing magnet, triggers the position sensor device to read the position of an adjacent passing magnet. The strain in the gauge length is determined from the read position. RFID tags placed on the member between the magnets can be identified by an RF reader to identify a particular gauge length being measured. The system can include a deployment device for feeding the member along the desired path.

    Abstract: A force sensor includes a shaft to which a magnet is fixed, and a case which can reciprocate with respect to the shaft and to which a Hall IC element is fixed. The Hall IC element outputs an output voltage which changes in accordance with relative displacement between the Hall IC element and the magnet. A main spring is interposed between the shaft and the case and elastically deforms in accordance with force produced between the shaft and the case in the reciprocating direction. A sub spring is provided in order to impart a preload such that when the amount of elastic deformation of the main spring is substantially zero, no axial clearance is formed between a flange portion of the shaft and one end portion of the main spring, and no axial clearance is formed between the case and the other end of the main spring.
