Key Features

Absolute vibration measurement
Measures vibration velocity of bearing boxes, casings, and structural components relative to free space, providing reliable indication of machine health.

Two-wire loop-powered design
Simplifies installation and wiring, eliminates the need for an external power supply, and supports both portable measurement and permanent installation.

Wide temperature range & strong anti-interference performance
Impact-resistant and corrosion-resistant design, suitable for harsh industrial environments.

Broad application scope
Ideal for rotating machinery such as steam turbines, compressors, pumps, and fans in petrochemical, power generation, metallurgy, and other heavy industries.

System compatibility
Fully compatible with 3500 series monitoring systems and speed/displacement converters, enabling vibration data acquisition, alarm management, and predictive maintenance.
