A torque sensor measures the rotational force exerted on objects such as shafts, motors or system components. This force, known as torque, is key to making machines like motors and engines work efficiently and safely. eTAZ systems helps industries monitor performance and effectively manage energy consumption. We commonly use torque sensors in a variety of applications, including automotive testing, industrial machinery, and aerospace equipment. Their ability to accurately measure torque enables engineers to optimize processes, prevent equipment failures and increase performance.
How do torque sensors work?
Torque sensors work by converting torque into an electrical signal that is then measured and analyzed.
There are two primary categories of torque sensors
Rotary Torque Converters: Employed to gauge torque in revolving components like shafts.
Reaction Torque Sensors: Measures torque in stationary parts, often used in engine performance testing. The fundamental mechanism varies based on the kind of sensor.
Common methods include: Strain gauge torque sensors: Use strain gauges attached to rotating shafts where the deformation due to torque changes the electrical resistance.
Magnetoelastic torque sensors: Measures changes in magnetic properties caused by torque applied to ferromagnetic materials.
Optical torque sensors: Use laser technology or light interference to detect angular displacement induced by torque. Each type has pros and cons depending on accuracy, environmental conditions and cost.
