Cable Tensiometers are hand-held instruments used to measure the tension of a cable. They are often used in the aviation industry during cable rigging in aircraft by aircraft manufacturers and for periodic cable maintenance by aircraft maintenance technicians. Cables are used in an aircraft to connect the flight controls in the cockpit with the movable parts on the aircraft’s wings and stabilizers, such as the ailerons, elevators, and rudder. Cable rigging involves the setting of the travel limits and cable tensions of the cables in the aircraft control system.
