Which instrument is used to measure the tension in a belt?

The instrument that is utilized to measure the tension in a belt is the belt tension gauge. This tool is specifically designed for this purpose and provides readings that help technicians ensure the belt operates within the recommended tension range, which is crucial for efficient power transmission and longevity of the belt and accompanying components.

By accurately measuring the tension, the gauge allows for adjustments to be made, preventing issues such as slippage or excessive wear. This is particularly important in various applications, including machinery and automotive systems, where the right tension can impact performance and energy efficiency.

Other tools listed, such as a torque wrench, are used to measure torque applied to a fastener, a vibration analyzer assesses mechanical vibration to diagnose issues related to unbalance or misalignment, and a pressure gauge measures the pressure of fluids. While these instruments are essential in their respective functions, they do not provide the specific measurement related to belt tension.
