HZW Axial displacement (differential expansion) monitoring instrumentDetailed product description：

The HZW axial displacement (differential expansion) monitoring and protection device is used in conjunction with the WT type eddy current sensor. It utilizes the principle of eddy current to monitor, measure, and protect the axial displacement (differential expansion) of rotating machinery such as steam turbines and fans in a non-contact manner, and can automatically provide alarm and shutdown protection signals and alarm contact outputs.

The device has reliable quality, stable performance, large linear range, high accuracy, wide frequency response, good temperature characteristics, and is not affected by oil stains, steam, and other media during detection.
