4. Core Product Advantages

The 330101-00-20-05-02-00 8mm proximity probe inherits all high-performance characteristics of the 3300 XL series, with outstanding stability and compatibility for industrial core equipment monitoring. The 7.87V/mm high linear sensitivity ensures accurate capture of tiny shaft vibration and displacement changes, effectively identifying early faults such as rotor unbalance, shaft friction and bearing looseness. The 20-meter factory integrated cable eliminates on-site welding and wiring errors, greatly improving construction efficiency and signal consistency.

Adopting advanced eddy-current non-contact measurement technology, it has no mechanical wear, zero friction loss and ultra-long service life compared with contact sensors. The full stainless steel sealed structure resists oil pollution, dust and conventional chemical corrosion, adapting to complex working conditions of unit oil stations and factory equipment. Standard API 670 industrial grade and complete hazardous area certifications ensure reliable operation in petrochemical and power plant explosive environments, supporting 7×24-hour uninterrupted online monitoring.

5. Industrial Application Scenarios

This 330101 long-cable proximity probe is mainly applicable to medium and large core rotating machinery monitoring scenarios requiring long-distance wiring. In thermal power plants, it is widely used for steam turbine shaft vibration, thrust displacement and rotor position monitoring, serving as the core sensing component of unit TSI protection system. In petrochemical and natural gas industries, it monitors high-speed centrifugal compressors, turbo-expanders and process pressurization equipment, providing accurate displacement data for equipment safety interlock. It is also commonly deployed in metallurgical heavy industry and industrial large generator sets, solving the wiring distance limitation of short probes, and realizing stable long-distance signal transmission for centralized cabinet arrangement sites.
