What Is Wrench Calibration Tester

The wrench calibration tester is a compact digital test instrument designed to measure the torque settings on standard 'beam', 'click' and 'break-over' wrenches. It can easily be mounted on any workbench and the torque sensor features a handy square-drive for connection of common adaptors.

 

 

Why Do Wrenches Need to Be Calibrated with a Wrench Calibration Tester

This is essential to ensure the continuity of your production process. It doesn't matter if you're using a small torque wrench or a bigger one, both must work within strict tolerances to provide the right force to tighten bolts or nuts as required.
A properly calibrated wrench will accurately measure torque, allowing a fastener to be tightened with the correct tension and preventing mutual connection failures. An excessive deviation can result in less reliable or vulnerable bolt connections.

How Does Wrench Calibration Tester Works

 

As the operator ratchets the torque wrench up and down, will measure the torque being applied.


These measurements are sent directly to a paired instrument. Depending on instrument selection, the operator can either view the data on a digital display or stream the data directly onto a PC.


If the data shows any anomalies, the torque wrench may be in need of a recalibration to meet its intended spec.


Every wrench calibration tester is prone to measurement errors. These structural uncertainties are the simply algebraic difference between the value that is indicated by the wrench calibration tester output versus the actual value of the measured variable, or known reference loads. Measurement errors can be caused by many factors:

 

● Zero offset (or load cell zero balance)

 

● Linearity (or non-linearity)

 

● Hysteresis

 

● Repeatability (or non-repeatability)

 

● Temperature shift span and zero

What Is Torque tester

A torque tester is a quality control device to test or calibrate torque-controlled tools. This includes electronic torque wrenches, click torque wrenches, dial torque wrenches, electric screwdrivers, air screwdrivers, pulse tools, cordless screwdrivers, nutrunners, and torque screwdrivers. Advanced torque testers include the ability to measure in clockwise and counter-clockwise directions,[1] and potentially convert to engineering units (such as in·oz, in·lb, ft·lb, N·m, cN·m, kgf·cm, gf·cm, kgf·fm). They can also have different modes of operation (such as peak, 1st peak, track), and may include a certificate from a local regulator.

The association between tension and torque should be considered carefully, since it is quite hard to specify the variation of conditions of a wrench. The amount of the twisting force necessary to rotate the nut along the bolt threads is known as torque, however tension is the elongation or elasticity of a wrench that provides the holding force of a joint.


Wrenches are intended to stretch or give slightly, and the clamping load that develops during this elastic elongation is what makes the joints lock together. Torque is an incidental indication of tension, as many factors can disturb this association, such as texture of the mating surfaces, oils, rubbish, thread series, rust and material type, for instance. Almost all tables about the torque/tension relationship that have been established, including ours, are based on the following formula:


T = (K D P)/12
All of the following terms refer to the mechanical properties that aid to define the anticipated tensile strength performance of a precise wrench and can be calculated in units of force. The force is typically reported in Newtons (N) and/or pound-force (lbf). Sometimes these forces are reported in kilonewton (kN) and kilopound-force (kip). The difference is that one is used for standard measurements (inches) and the other is mostly used for metric measurements (mm).


Applying sufficient tensile force to a wrench where the outcome will not show plastic deformation is known as proof load. Proof load is considered to be around 85% – 95% of the yield strength. That is to say, the wrench must stay in its elastic range when force is applied up to its proof load. We can define Yield Strength as the tensile force that will produce permanent distortion (most commonly at 0.2% plastic strain) on a specified wrench. The maximum force a wrench must tolerate before fracture is defined as Ultimate Tensile Strength.

 

How to Use a Torque Tester

 

Choose a torque tester that suits your needs based on the required torque range, accuracy, and application environment. Different models and specifications of torque testers have distinct features, so choose one according to your specific requirements.


Connect the test piece
Connect the bolt, nut, or other connecting components to the torque tester. Ensure a secure and tight connection to avoid any looseness that might affect the accuracy of the measurement.


Set the torque value
Set the desired torque value as per the requirements. Torque testers typically have the functionality to adjust torque values, and this can be done through knobs, buttons, or a touchscreen interface.


Perform the measurement
Hold the torque tester vertically and rotate it to apply the required torque. Maintain a stable and uniform rotation speed to ensure the accuracy of the measurement.


Record the measurement results
After completing the measurement, record the measured torque value. Torque testers usually come with a display screen or data storage capability, enabling direct viewing and saving measurement results.


Calibration and maintenance
Regular torque tester calibration and maintenance are crucial steps to ensure measurement accuracy and equipment stability. Follow the calibration procedures and maintenance guidelines provided by the manufacturer.

How Accurate Is a Torque Tester

Torque tester for all small hand tools & non-impacting power tools. Accuracy ± 0.5% of reading from 20% to 100% of full scale.


When you work with torque tools, a tool that is functioning out of tolerance or has been inaccurately calibrated can result in tool breakage as well as potentially catastrophic damage and expense to the project you're working on. Torque tools must be tested regularly to ensure they are within tolerance and recalibrated as needed, which adds to the cost of ownership over the life of the tool. The right torque measurement tool allows for interim testing, to ensure that you're not recalibrating on a calendar schedule, but only when recalibration is actually needed. This results in less downtime and reduced cost of ownership for your torque tools.


Use our torque wrench testers for click, dial, hydraulic, impact, and manual wrenches. Our range of torque calibrators and testers also check manual and power screwdrivers, digital power tools, power drivers, and any other torque tool. Our testers are available in a wide range of capacities, from 10 oz-in to 25,000 lb-ft, and in multiple measuring units.

 

How Often Should a Torque Tester Be Calibrated
 
 

One way or another, as you use your torque tools, they will fall out of calibration. That doesn't mean there's anything wrong with your tools or even that it's a bad thing that they go out of calibration from time to time. It's a natural part of life, a force of nature. However, the negative outcome is if you unknowingly use the tools to create defective or faulty products. At that point, you may be liable for product failure in the field and will have to deal with the repercussions.

 
 

The best way—really, the only way—to be certain your torque tools are in alignment when you use them is to test them, regularly. A tool that needs to be tested with each new fastener would be more trouble than it's worth. On the other hand, if you test your tool only once every few years, then if you find it out of calibration, you'll have difficulty figuring out how long it has been that way and how many potentially defective products it has created in the meantime.

 
 

As a general rule of thumb, it's wise to test the calibration of your torque tools every six months or twelve months. That's rare enough that it doesn't impede productivity and often enough that it doesn't create obscene liabilities. The organization that owns the tool must determine a suitable calibration frequency that meets its needs based on many factors, such as equipment performance history, application, degree of usage, and management objectives.

 
 

Naturally, tools that show visible signs of wear, such as old grease, worn parts, or loose screws, should be pulled from service and inspected as well. Tools that have been found out of calibration should be flagged and retested at half the normal interval. While these general rules are useful as guidelines, your operation's specific calibration intervals will depend on the precision you need, the exact tools you're using, the fasteners you're working with, the criticality of your application, and potentially the legal requirements which govern your industry.

FAQ
 

Q: What is the function of torque wrench tester?

A: A torque tester is a quality control device to test or calibrate torque controlled tools. This includes electronic torque wrenches, click torque wrenches, dial torque wrenches, electric screwdrivers, air screwdrivers, pulse tools, cordless screwdrivers, nutrunners, and torque screwdrivers.

Q: Why use a torque tester?

A: Torque testing is a way of determining how an object will react when it is being turned - during normal operation or being twisted until it deliberately fails or breaks. This rotational force can be 'dynamic' often delivered at ultra-high speed or 'static' at a much lower speed.

Q: How does a torque tester work?

A: By definition, torque tester is a type of transducer, specifically a torque transducer that converts a torque measurement (reaction, dynamic or rotary) into another physical variable, in this case, into an electrical signal that can be measured, converted and standardized.

If you don't hear a click, then move the weight farther from the head of the wrench and try again. Make a definitive mark after two or three stops in the same location of the wrench.

Q: How does a torque tester work?

A: Through a mechanical arrangement, the torque being sensed deforms a strain gauge. The strain gauge converts the deformation (strain) to electrical signals. A torque transducer usually consists of four strain gauges in a Wheatstone bridge configuration. Torque transducers of one or two strain gauges are also available.

Q: How to use a torque tester?

A: The shaft, or rotor, moves while the housing, or stator, is fixed. Both parts are interconnected by low-friction, zero-play bearings. The transducer can be incorporated in a structure or test bench by means of hub-type clamps on both ends of the shaft.

Q: How does wrench calibration tester works?
