Torque torque

The torque sensors are essential devices for measuring the moment of force applied to an object, allowing the evaluation of rotation or torsion in shafts and mechanical components. Below are the main technologies used to measure torque, their operating principles, advantages, disadvantages and applications:

1. Torque Sensors Based on Magnetostrictive Technology (NCTE): These sensors use the magnetostrictive property of certain materials, which undergo deformation when magnetized. When a torque is applied, a variation in the magnetic field is generated, which is detected and converted into an electrical signal proportional to the torque.

2. Strain Gauge Based Torque Sensors: These sensors incorporate strain gauges attached to a shaft or torsion bar. When a torque is applied, the shaft deforms, altering the electrical resistance of the gauges, allowing the applied torque to be calculated. They can be static or dynamic. Static ones measure the torque applied to an object at rest, generally using strain gauges or piezoelectric sensors. Dynamic ones are usually brush-based, transmitting the signal from the strain gauges through the brushes and slip rings.

Selecting the right torque sensor depends on factors such as the specific application, operating conditions, required accuracy, and available budget. It is essential to evaluate each technology based on the particular needs of the measurement to ensure accurate and reliable results.
