In situations where we need to have precision in the tasks we are performing, it is important to have the right tools to perform that task.
The torque wrench is a high precision tool, widely used in many workshops and industries. Next we will know what a torque meter is, how it works and what types there are.
What is a torque meter?
The torque wrench is a tool that is used to apply a certain torque to certain parts, such as screws , nuts, etc. The main feature of this tool is its ability to apply a specific tension with high precision.
This is why they are widely used in places where precise torque is critical, such as combustion engines , equipment that handles high pressure, pipes, among others.
Torque wrench types
There are different types of torque wrenches to make adjustments to parts, but they have different characteristics or different purposes. Among the types of torque meters we find:
- Torque multiplier: They are torque meters that allow to increase the value of the applied torque.
- Multitorque: The main feature of this torque meter is that it has a data collection system which is used with extensions, sockets, handles or a combination of these.
- Computorque electronic torque meter: It is a type of torque meter that allows several applications but is mainly characterized by having a greater precision than the others.
- Dial Torquemeter: Measures torque through a dial making a quick and accurate reading of it.
- Thunder torque meter: In this case, the torque to be applied is determined before performing the operation.
- Pre-set torque wrenches: They have pre-set values and are used in production lines where the task is repetitive.
How to use a torque wrench
Below we will detail the steps to follow to correctly use an analog or needle torque wrench.
- First of all, the torque that must be given to the piece must be known. Usually this data comes in the manufacturer’s specifications.
- Adjust the piece until it arrives. Then place the analog torquemeter on the piece.
- Move the torque meter tightening the piece, until on the scale we see that the needle reaches the desired value. In that case the torque would already be applied.
Parts of a torque wrench
The parts of a torque wrench are:
- Input: They can be 1/4”, 3/8”, 1/2”, 3/4”, each of these inputs will apply a different force for the different sizes of pieces.
- Rotation selector: Allows torque for both the left and right sides
- Scale: Shows the torque values that are applied in different measurement units.
- Safe: Allows that once the required torque is applied, it does not continue to apply or does not reduce the torque already made. “Lock” the torque wrench.
What is a torque meter used for?
The torque meter is used in case an adequate tightening has to be given, according to a specified torque for that part. There are pieces in which it is important that they have a torque based on the specifications given by the manufacturer because if, for example, we exceed the torque, the piece can become unbalanced, break, crack, or it can damage another nearby piece.
Clearly, it is not necessary to use a torque wrench in cases where a “strong tightening” simply has to be done, without the need to know the value of the torque that was applied.
