It is commonly deployed in steam turbines, gas turbines, hydro turbines, centrifugal compressors, pumps, and large rotating industrial drives. Within turbine systems, it provides continuous radial vibration and axial position monitoring. In compressor and pump applications, it supports early identification of mechanical degradation such as rotor instability, misalignment, imbalance, and bearing wear.
It is also widely integrated into API 670-compliant protection systems, where uninterrupted real-time vibration measurement is required to safeguard critical rotating assets across power generation, oil and gas, and petrochemical industries.
Advantages
This sensor is designed to deliver high measurement accuracy and long-term operational stability in harsh industrial environments.
It uses eddy current technology to achieve non-contact displacement sensing with excellent linear response, ensuring reliable tracking of shaft movement even at high rotational speeds. The 16mm probe geometry provides a stable electromagnetic field profile, supporting consistent measurement performance across varying shaft conditions.
The construction is optimized for resistance to temperature fluctuation, vibration stress, and electromagnetic interference. Its low drift characteristics contribute to extended calibration stability, reducing maintenance frequency and improving overall system uptime in continuous monitoring applications.
