Technical details and manufacturing context for Torque Sensor

Definition
A torque sensor is a critical component within a Torque Control System that precisely measures the rotational force applied to a shaft or rotating element. It converts mechanical torque into proportional electrical signals (typically voltage, current, or frequency) that are used by the system's controller to monitor, regulate, and maintain desired torque levels in machinery and equipment.
Working Principle
Torque sensors operate by measuring the torsional deformation (shear strain) of a shaft or sensing element when torque is applied. This deformation is detected using various technologies such as strain gauges (which change electrical resistance), magnetoelastic effects (changing magnetic properties), or optical methods. The resulting signal is amplified, conditioned, and transmitted to the control system.
Common Materials
Stainless steel, Alloy steel, Strain gauge foil, Electrical insulation materials
Technical Parameters
