Description

Technical Field

[0001] This utility model relates to the field of limiting device technology, and in particular to a limiting device for a magnetoresistive displacement sensor testing device. Background Technology

[0002] In modern industrial production and scientific research, displacement sensors are increasingly widely used, among which magnetoresistive displacement sensors are highly favored due to their high precision, high stability, and low sensitivity to environmental conditions. However, in practical applications, the testing of magnetoresistive displacement sensors often faces some challenges and problems.

[0003] Traditional displacement sensor testing equipment often lacks an effective clamping and fixing mechanism, which can lead to sensor loosening or positional displacement during testing. This not only affects the accuracy of test data but also hinders rapid sensor installation. Furthermore, when testing objects of varying weights or impact forces, existing equipment struggles to provide sufficient cushioning to mitigate the impact on the sensor and testing device, thus limiting the equipment's lifespan and increasing maintenance costs. To overcome these shortcomings and improve the stability and safety of magnetoresistive displacement sensor testing, it is necessary to design a novel limiting device. Utility Model Content
