What is a Torque Wrench?
Torque is a measure of how much force is applied at a point in distance and the type of torque sensor used will impact the accuracy of the measurement. Dynamic torques are measured using strain gauges, which are bonded to shafts in a specific pattern that varies based on the desired measurement range. Strain gauges typically have lower sensitivity levels than traditional transducers and cannot be used without special care due to hysteresis effects that can cause drift. Strain gauges are low cost and easy to mount, but may require some setup time depending on your application.
A digital torque wrench offers many advantages over a traditional analog one. First, it displays the exact amount of torque as you are applying it, which means there’s no guesswork. They also have more precision and accuracy than an analog model. Finally, they can be used with an automatic calibration system that automatically resets the device after you have applied the desired torque force.
The Digital Torque Wrench is accurate and easy to use.
Torque is the rotational force that produces or resists motion. Torque can be static or dynamic, depending on whether there is angular acceleration. The torque exerted by a clock spring would be static, since there is no rotation and, hence, no angular acceleration.
Relationship between dynamic force and moment. This relationship is described by Newton's second law; F=ma (force equals mass times acceleration). In order to stop your car with its substantial mass, a dynamic force is required. Torque is best represented as the force required over a distance or distance times force. Torque is used to express the amount of twisting force applied to a bolt or nut. It is one of the most important concepts in physics, and it's critical in building cars and other machines that are the backbone of our modern economy.
The digital torque wrench with a built-in plus/minus Error Indicator (see description below) helps to reduce over or under tightening situations. The error indicator feature is an excellent graduation check and helps verify that the user has the correct feel for setting the desired torque.
