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.
FORCES SENSORS FOR MACHINING MONITORING
Single axis force feedback table – Capable of measuring forces in one direction only with a range of ±20kN, a resolution of 12N and accuracy of better than 50N at 1kHz the table has dimensions of diameter 100mm and a height of 70mm.
Contactless torque sensors CTS
CEDRAT TECHNOLOGIES proposes new patented cost effective contact less sensors. The concept is so modular and versatile that customized OEM products can be rapidly developed. The concept is based on the use of a torsion converter and a proximity sensor.

Magnetostrictive Stress Sensor
This Contactless Stress Sensor uses the Magnetostriction (magnetoelasticity) of the steel part or cable where it is located to measure the static & dynamic forces. It was developped for Freyssinet and EDF, for prestressed concrete monitoring.
