How to avoid overload damage of tension sensor?

In order to avoid overload damage of the tension sensor, the following measures can be taken:

Estimate the load of the test object: before the test, fully understand the test object, estimate its load, and select the appropriate sensor to ensure that the test object will not exceed the rated load capacity of the sensor.

Control the test speed: avoid the overload caused by the sensor's failure to respond in time due to too fast test speed.

Install the sensor correctly: when installing the sensor, ensure that the force is uniform and avoid uneven pressure on the sensor.

Setting the alarm or stopping force value: Set the alarm or stopping force value on the tensile testing machine. When the force value of the mechanical sensor reaches the set value, the equipment will give an alarm and stop running to avoid overload damage.

Check the sensor status regularly: check the sensor status regularly and replace the aging or damaged sensor in time to ensure the accuracy of the test.

Increase pre-compression or pre-stretching elastic device: add pre-compression or pre-stretching elastic device between the moving beam and the fixed beam. When the load reaches the pre-compression force or pre-stretching force, the elastic device will continue to deform, so that the compression or stretching of an elastic device will change in addition to the compression or stretching of the sample, and the deformation amount will increase when the force is the same, or the force will be smaller when the deformation is the same. In this way, combined with the protection method of setting margin on the range and the closed-loop control method, it can be ensured that the pressure sensor will reach the failure limit.

Training testers: Improve testers' knowledge and operational skills on the use of sensors, and ensure that they can use and maintain sensors correctly.

To sum up, the overload damage of the tension sensor can be effectively avoided through the solutions and preventive measures of Huili.
