工作原理
Works on the principle of torsional strain measurement. When torque is applied, the shaft experiences angular deformation proportional to the torque. Strain gauges bonded to the shaft surface detect this deformation through resistance changes, which are converted to electrical signals via Wheatstone bridge circuits. The measured strain correlates directly with applied torque through the shaft's material properties and geometry.

常见问题

What is the difference between a sensing shaft and a regular drive shaft?

A sensing shaft incorporates strain gauges or other sensing elements to measure torque, while a regular drive shaft only transmits torque without measurement capability. Sensing shafts have precise material properties and surface finishes optimized for accurate strain measurement.

How are strain gauges attached to sensing shafts?

Strain gauges are precision-bonded using specialized adhesives (typically epoxy-based) to carefully prepared surfaces. The bonding process includes surface cleaning, application of adhesive, precise gauge alignment, and curing under controlled conditions to ensure optimal strain transfer and long-term stability.

What maintenance do sensing shafts require?

Regular inspection for surface damage, verification of electrical connections, and calibration checks. Protection from excessive moisture, chemicals, and mechanical overload is essential. Recalibration is recommended annually or per manufacturer specifications.
