If you need a torque wrench, then you are in the right place. This article will cover the different types, the importance of accuracy, and how to maintain a torque wrench. Despite their many benefits, there are several things you need to keep in mind before you make your purchase. This article will cover the most common types of torque wrenches and how they can be useful to you. It will also touch on the problems that you may run into when using your torque wrench.
Accuracy of Torque Wrenches
Torque wrench accuracy is measured by two important metrics. Full-scale accuracy refers to the allowable error for a torque wrench across the entire range of settings. The tolerance for this parameter varies from 5% to 50%. Indicated-value accuracy refers to the error at a particular set point. In general, the lower the range, the better the accuracy. This measurement is especially important in determining the correct torque level.
To determine the accuracy of a torque wrench, perform a calibration process. This involves comparing the set value to its true value. A simple example of this is placing a 05-pound weight on a weighing scale. A scale that reads 5.5 pounds is not accurate. In the case of torque wrenches, a more advanced calibration method involves setting the torque wrench to the lowest setting and waiting at least 24 hours before calibrating it.
Types of Torque Wrenches
In the world of automotive mechanics, torque wrenches are used to apply force and tighten nuts and bolts. These tools are very useful in automotive repair shops because they allow you to adjust the torque to achieve the right results. To choose the right torque wrench, it is important to understand the difference between different types. Here are some of the most common types. Each type has a unique set of features and benefits. Listed below are some of the benefits of each type.
The beam torque wrench is the simplest type of torque wrench. It consists of a lever arm with a head and a handle. The arm has a certain degree of elasticity that bends with the level of pressure applied. When not in use, the indicator stays parallel to the arm. When the torque wrench is in use, the scale moves, giving the operator a reading. It resembles a weighing scale with a needle pointer.
Maintenance of Torque Wrenches
There are several different methods of maintaining torque wrenches. Although many people think that servicing a torque wrench isn't necessary, the fact is that it should be done on a regular basis. In general, torque wrenches should be re-calibrated every 5,000 cycles. You should also inspect your torque wrench for excessive wear and tear. Old grease, loose components, and unstable joints should be replaced or repaired before the next use. Frequent calibration may also be necessary if you use your torque wrench frequently, or if you drop it.
One method of maintenance is to perform routine tool calibrations. This will help maintain the accuracy of your torque tool and will also help you identify OOT (Out of Tolerance) torque tools. The tool should be re-calibrated as needed if it becomes Out of Tolerance. It may also be out of tolerance if it has not been used for a while. Performing routine calibrations on torque tools is very important to ensure that they are always working correctly.
Dissatisfaction with Torque Wrenches
The first torque wrench was invented by Conrad Bahr in 1918, while working for the New York City Water Department. He had experienced inconsistency in the tightening of flange bolts and claimed to have invented a device to eliminate this problem. Another inventor, George Pfeffer, worked for S.R. Dresser Manufacturing Co. and holds several patents. Although both men did not have a successful commercial product, their innovations were influential in the development of torque wrenches.
The accuracy of torque wrenches can be rated in terms of Full Scale (FS) or Indicated Value (IV). FS states the amount of allowable error over the full scale. IV states the allowable error at the set point. The lower the number, the more accurate the torque wrench is. A table of full-scale and indicated-value torque wrench accuracy can help you determine which one is right for your needs.
