Product Applications

Oil & Gas: Used for monitoring large drilling platforms and key rotating equipment in refineries, such as centrifuges and compressors.

Power Generation: Continuously monitors the bearing vibration and displacement of gas turbines, steam turbines and generators in power plants.

Chemical and Hydrocarbon Processing: Particularly suitable for production lines handling toxic or flammable materials, combined with monitoring systems (such as Trendmaster Pro) to detect mechanical failures.

Heavy Industry Manufacturing: Applied to the health monitoring of various pumps, electric motors, fans and reciprocating compressors to prevent downtime risks caused by sudden mechanical failures. 

Main functions and uses

Axis vibration measurement: Monitoring the radial vibration of rotating axes, identifying imbalance, misalignment or bearing wear.

Axis position monitoring: Measuring axial displacement (thrust position) to prevent rotor from colliding with stator.

Predictive maintenance: Providing non-contact, precise static and dynamic displacement data, enabling enterprises to carry out maintenance based on the actual operating condition of the equipment rather than fixed time, thereby reducing maintenance costs.
