Abstract

A sensor assembly for sensing tension in a rope is disclosed. The sensor assembly comprises: a housing, a force sensor for sensing mechanical force applied to the housing located outside the housing, and a controller for controlling the force sensor located inside the housing. The housing protects the controller from damage resulting from compression and/or environmental conditions, such as water ingress. By locating the sensor assembly outside of the housing the force sensor may thereby be exposed directly to force applied to the sensor assembly in use. Consequently, the accuracy and reliability of force sensing by the sensor assembly may desirably be improved. The force sensor could, for example, comprise a strain gauge.
