The pressductor and the torductor — Two heavy-duty transducers based on magnetic stress sensitivity

Two transducers for force and stress, the pressductor and the torductor, employ magnetic stress sensitivity in different ways. The pressductor is a transducer for compressive force, composed of a large number of equal measuring elements; each of these takes its share of the force and renders a proportional contribution to the output voltage. This results in an actual force integration over the loaded area and a very high output power. The torductor is a noncontacting transducer for stress, which is particularly suitable for measuring torque in rotating shafts, as it works without slip rings or any other shaft attachments, and has a high output power.
