Technical details and manufacturing context for Torque Sensor (if equipped)

Definition

A torque sensor is a precision measurement component integrated into torque adjustment mechanisms to monitor and quantify the rotational force being applied. It provides real-time feedback to control systems, enabling precise torque regulation, overload protection, and performance optimization in mechanical assemblies. The sensor typically operates by measuring strain, torsion, or magnetic effects on a shaft. Common methods include strain gauges that detect minute deformations, magnetoelastic principles where torque changes magnetic permeability, or optical encoders measuring angular deflection. The sensor converts this physical change into an electrical signal proportional to the applied torque. This signal can be used for process control, data logging, or safety interlocks. The sensor is designed for industrial environments, with a rated torque range of 0.5–100 N·m, accuracy class ±0.5% FS per ISO 7500-1, and overload capacity of 120%. It outputs a 4–20 mA analog current loop signal, operates on 24 V DC (±10%), and functions within -40 to 85 °C. The housing offers ingress protection from IP54 to IP65 per IEC 60529. Materials include stainless steel (17-4PH per ASTM A693), aluminum alloy, strain gauge foil, and epoxy resin. Weight ranges from 0.5 to 2.5 kg depending on rated torque and design. These specifications are reference values; verify model-specific data with the legal manufacturer or supplier before procurement.

Working Principle

The sensor measures torque by detecting physical changes in a shaft. Strain gauges bonded to the shaft deform under torsional stress, changing electrical resistance. Magnetoelastic sensors exploit changes in magnetic permeability under torque. Optical encoders measure angular deflection between two points. The resulting signal is conditioned and output as a 4–20 mA current loop, proportional to applied torque.
