Most shaft tension sensors operate on the strain gauge principle. When tension is applied, the shaft or sensor element deforms slightly. This deformation changes the electrical resistance of the strain gauge, which is measured and converted into a tension value.
The sensor typically consists of a shaft or beam element with strain gauges bonded to its surface. When the shaft experiences tension or torque, it bends or twists minutely, causing the strain gauges to stretch or compress. This mechanical strain alters the electrical resistance of the gauges, which is detected by a Wheatstone bridge circuit and converted into an electrical signal proportional to the applied tension.
Proper installation and alignment are crucial for accurate measurements. Couplings at both ends of the sensor shaft prevent damage and false readings by isolating the sensor from misalignment and external forces. Calibration ensures ongoing accuracy, especially in varying environmental conditions such as temperature fluctuations and mechanical vibrations.
In some applications, multiple sensors are used in tandem to measure complex tension profiles or to provide redundancy for safety-critical systems.
Shaft tension sensors are vital components across numerous industries, from manufacturing and automotive to aerospace and medical fields. Their ability to provide precise tension measurements ensures product quality, operational efficiency, and safety.
