Kiertomittauslaitteet

Kiertomittauslaitteet, known in English as torque wrenches or dynamometers, are specialized tools designed to measure and apply a precise amount of rotational force, or torque. These devices are crucial in various mechanical and engineering applications where the correct tightness of a fastener, such as a bolt or nut, is critical for performance and safety. Incorrect torque can lead to over-tightening, potentially stripping threads or damaging components, or under-tightening, which can result in loosening and failure.

There are several types of kiertomittauslaitteet. Click-type torque wrenches are common; they emit an audible and tactile click when the preset torque is reached. Beam-type torque wrenches use a flexible beam that deflects, with a pointer indicating the applied torque on a calibrated scale. Digital torque wrenches offer electronic readouts and often include features like data logging and audible alarms. Hydraulic or pneumatic torque wrenches are used for high-torque applications, often in industrial settings, and can be powered by compressed air or hydraulic fluid.

The accuracy of a kiertomittauslaite is paramount. They are typically calibrated regularly to ensure they consistently deliver the specified torque. These instruments find widespread use in automotive repair, aerospace manufacturing, bicycle maintenance, and anywhere precise fastening is required to ensure structural integrity and prevent mechanical failure.
