Accurate torque measurements for rotating or stationary shafts are provided by a relatively new type of sensor that uses non-contact sensing and is based on the magnetoelastic effect. A ferromagnetic ring fastened to the shaft being measured is the essential part of a magnetoelastic sensor.
Amorphous ferromagnetic ribbons used as magnetoelastic sensors exhibit a magneto-mechanical resonance when stimulated by an altering external magnetic field. An MES’s anisotropy and susceptibility, which are closely related to its magnetic permeability, can change in response to an applied stress.
To convert mechanical torque into an electrical signal, a sensor is called a torque sensor. We produce two types at FUTEK: reaction and rotary. Both types operate differently even though they both measure torque.
Reaction The reaction force produced by an object producing torque is measured by torque sensors. uses a ferromagnetic metal that, at the molecular level, aligns itself with magnetic fields.
The magnetostrictive level sensor can produce a signal indicating the liquid level by generating two competing magnetic fields.
Global Magneto elastic torque sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
NSK Develops World’s First Non-Contact Torque Sensor for Drive Shafts in Motor Vehicles. This new technology can increase fuel economy (reduce power consumption), improve ride comfort and safety, and open up a world of new possibilities across CASE.
NSK has newly developed a non-contact torque sensor capable of measuring the torque of drive shafts in vehicles in real time. This is the first sensor in the world of this type and capability.
The sensor uses magnetic fields to detect torque by measuring minute twisting of the drive shaft that occurs naturally as it is rotated by the motor.
Conventional torque sensors have been too complicated or expensive for wide scale use, but NSK’s new technology makes possible a compact sensor with a simple structure that is ideal for mass production and broad adoption by automakers.
