1、 Product Overview
CWY-DO-501Eddy current sensor axis displacement/flight vibration plateAs a precise sensing device for shaft health monitoring, a non-contact displacement monitoring scheme based on the principle of eddy current effect is developed, which can accurately measure key parameters such as radial displacement, axial displacement, eccentricity, and sway of rotating machinery shaft systems in real time.
The product adopts an integrated probe and preamplifier design, which has the characteristics of strong anti-interference, fast response speed, and high measurement accuracy. It is suitable for shaft status monitoring of key equipment such as steam turbines, generators, and centrifuges. It provides reliable data support for early warning of equipment rotor imbalance, misalignment, and bearing wear, and is the core monitoring component for ensuring long-term stable operation of equipment in industries such as power, petrochemicals, and metallurgy.
2、 Core advantages
(1) Micro scale precise measurement with strong data reliability
The conventional measurement range is 0-5mm, with a resolution of 0.1 μ m and a linear error of ≤± 1%. It can accurately capture small displacement changes in the shaft system, avoiding misjudgment caused by measurement deviation; The standard linear range is 5mm, supporting customized ranges of 2mm-10mm, suitable for monitoring requirements of rotors with different shaft diameters from 50mm to 500mm, with stable linearity and no drift.
(2) Non contact design, zero wear and interference free
Maintain a gap of 0.5-2mm between the probe and the tested shaft system, without direct contact with moving parts, to avoid wear on the shaft surface or affecting the accuracy of equipment operation, and to extend the service life of equipment and sensors; The probe adopts a 316L stainless steel shell with a protection level of IP67, which can work stably in harsh industrial environments such as oil pollution, dust, and water vapor, and is not affected by the adhesion of media, thus ensuring measurement accuracy.
