What is the Purpose of a Torque Check?
The purpose of the torque check is to prevent various batch tightening accidents.
Through the final tightening inspection, the main problems found are:
The wrench was used incorrectly. Wrench failure. The torque coefficient is used incorrectly. Torque calculation error. Wrench calibration error. Preload loss is too large. Plate layers are not close together, etc.
What are the Methods of Torque Testing with a Rotary Torque Transducer?
Common torque measurement methods include: mechanical torque meter, electronic torque meter and optical torque meter.
The mechanical torque meter uses the lever principle for measurement. The torque value is determined by calculating the product of the force arm and the force at both ends of the lever. The electronic torque meter uses a transducer to detect the torque. It calculates the torque value through the internal circuit.
The optical torque meter uses the grating principle to measure the torque through the relative displacement between the grating and the sensor.
When measuring torque, it is crucial to choose the right torque meter. Different torque meters are suitable for different application scenarios. For example, the mechanical torque meter is suitable for low torque measurement. The electronic torque meter is suitable for high torque measurement. The optical torque meter is suitable for high-precision measurement.
When choosing a torque meter, you also need to consider factors such as its measurement range, accuracy and response speed.
The process of measuring torque usually includes the following steps:
Select a suitable torque meter according to the torque range to be measured.
Install the torque meter on the object to be measured and ensure that the connection between the torque meter and the object to be measured is firm and reliable.
Apply a certain torque to make the torque meter work.
Read the measurement results of the torque meter, record and analyze them.
In practical applications, there are also some things to pay attention to when measuring torque.
Ensure that the torque meter is installed correctly to avoid measurement errors caused by improper installation.
The torque should be applied evenly and smoothly to avoid measurement errors caused by uneven force.
Calibrate the torque meter regularly to ensure its measurement accuracy.
Record the measurement data for subsequent analysis and reference.
