Force & torque sensors

Sensing forces and torque are useful for most of mechatronic applications and detection systems, but are not always easy to integrate into the applications, especially when they relate to moving or vibrating parts, rotating shaft, etc.

Using its expertise in magnetic effects and in smart materials (piezoelectrics, magnetostrictives, magnetoelastics, LC resonance), CEDRAT TECHNOLOGIES has developed various force, stress and torque sensors (receiving transducers) for its customers, which meet stringent requirements from applications refered above. 

Examples of sensors below includes the CTS contactless torque sensor developed for cars with PSA, a contactless magnetic force sensor for chuck and pallet workholding systems in Machine Tools, a  magnetostrictive force sensor developed for prestressed concrete health monitoring with EDF and Freyssinet.

Other developments of CEDRAT TECHNOLOGIES in sensing and measuring include strain gauges sensors piezoelectric load cells, magnetic or piezoelectric energy harvesting, magnetic field sensors, etc.

To know more about our sensors see also our Piezo and magnetic Products, our acoustic & magnetic detection system and our related publications on sensors.
