Metrology Glossary: Torque Transducer

What Is A Torque Transducer?

A torque transducer is a device designed to gauge and record the rotational force applied to a rotating system. Torque, denoted in units of Newton-meters (Nm), signifies this rotational force. Typically, torque transducers function by assessing the deformation of a spring component. When torque is exerted on the transducer, the spring element undergoes deformation, and this alteration is quantified using strain gauges. The strain gauges transform the deformation into an electrical signal, which is then amplified and transformed into a digital signal. This digital signal can be exhibited on a display device or documented.

What Are Torque Transducers Used For?

Torque transducers are used in multiple applications across various industries. They are crucial for measuring torque in engines and motors, ensuring proper operation and performance optimization. Additionally, torque transducers are used in calibrating torque wrenches to guarantee precise torque application. Torque transducers also help monitor torque in industrial machinery, preventing damage and enhancing operational efficiency. They also find use in calibrating other torque sensors for accurate torque measurement. In research and development in fields such as automotive, aerospace, and manufacturing, torque transducers are used for developing new products and processes and improving existing ones.
