Torque tester

What is torque tester?

A torque tester which is meant to test or calibrate tools that are torque controlled. This includes:

  • Torque screwdrivers
  • Electronic torque wrenches
  • Electric screwdrivers
  • Dial torque wrenches
  • Air screwdrivers
  • Cordless screwdrivers and pulse tools.

Today’s torque testers have the ability to measure in both a counter-clockwise and clockwise direction. They can be used to convert over 8-Engineering units.

Applications of a torque tester

Torque is the angular force needed to turn things. One example is the force that is needed to turn a steering a wheel at a corner or the force needed for an airplane engine to turn the propeller.  Torque testing is needed when it comes to measuring how much torque can be applied to the objects.

There are two common applications in which torque testing is important. This is with fastening and with products that have rotating parts like transmissions, engines, and motors. When measuring and analyzing torque characteristics in these applications, it is possible to accurately determine the quality of the process or parts as well as the cause of the defects.

Different types of torque

Torque testing is required for the products that have rotating parts like engines.  Torque testing can be accomplished by inserting the torque transducer between the tools used for applying the force in the item against which the force has to be applied. There are two approaches for the torque measurement. They are in-line and reaction. In-line torque is used to test how much torque is needed to rotate some parts while the reaction is used to measure how much torque is required for preventing the part of the tool from rotating. There are sensors that have been specialized for every approach.

Common applications:

Assembling complex or large products involve hundreds or even thousands of fasteners. Most of them are screws and bolts.  When any fastener fails, the product’s integrity will be affected. This is why it is important for the manufacturer to ensure that every fastener has been fastened completely and has not been weakened or damaged in the fastening process.

  • Torque load cell

A torque cell is the load transducer that converts the torsional moment in the proportional electrical signal.  It is used in creating electrical signals that have a magnitude which is proportional to the force that is being measured.  There are many types of load cells, like strain gauge load cells, pneumatic load cells, and hydraulic load cells.

  • Axial Torque

Axial Torque is the tension that is defined as positive in the magnitude and negative in the compression. For the axial torque, the right-hand rule can be used as a sign for the convention. The positive axial torque vector points to the positive outward of the normal direction for the boundary elements.

  • High torque rotary actuator

The rotary actuator is the actuator used to produce torque and rotary motions. It is the simplest actuator that is completely mechanical if the linear motion is in one direction, and it gives rise to the rotation. There are other actuators that can be powered by hydraulic or pneumatic power, or they can use energy that has been stored within their springs.

  • Reaction torque sensor

This is the torque sensor, torque meter or torque transducer that is a device used to measure and record torque with its rotating system like a cap torque tester, bicycle crank, rotor, transmission, gearbox, crankshaft, and engine.

  • Reaction torque transducer

Also called a torque sensor, this is the device that is meant to measure and record the torque of a rotating system.  Measuring static torque is normally easier than measuring other types of torque.

  • Torque Actuator

Hydraulic actuators are used to convert the fluid pressure in the motion. This is the same as pneumatic actuators. They can be used for quarter-turn or linear valves. Fluid pressure acts on the piston to provide a linear thrust for the globe and gate valves. The quarter-turn actuator is capable of producing torque to offer a rotary motion to work on the quarter-turn valve.

What is a torque tester?

This is a tool that converts the torque in electrical signals. The conversion happens in two stages, and it is indirect. Using mechanical arrangements, the torque which has been sensed will deform the strain gauge. The key component for the modern torque tester is a digital display where the output signals are registered. A rundown fixture or joint simulator can be used in the calibration process, and it helps to test the power tools.

How a torque tester works

A torque tester is important because it gives information about the relative wear and tightness of every screw in the equipment.  The torque testers ensure that you can maintain the longevity and safety of your vehicle. Some tools can be expensive, but there are companies that will rent them out at a low rate.
