The VK-A Series vibration transducer is an eddy-current transducer
designed to measures the shaft vibration, and satisfies the
American Petroleum Institute API Standard 670.
The VK-P Series TSI transducer is exclusively designed for bearing position
and differential expansion measurement. This high-grade, eddy-current
type, non-contacting transducer offers lower temperature drift and stable
displacement measurement.
With a long cable extension feature, this transducer is most suitable for
power generation gas turbines and other types whose large size requires a
vibration transducer with a long cable length.
Many types of rotating machinery are utilized in the oil refining-
centered energy industry. To ensure safe operation of the machinery,
consistent monitoring is essential. In many cases, machinery failures
result in vibration value increases. Therefore, constant vibration value
monitoring promotes early irregularity detection and considers optimal
counter plans. SHINKAWA vibration monitoring products are varied
and flexible, adapting to any user’s customized system.

TRANSDUCER
VK-AThe VK-A series vibration transducer is an eddy-current transducer that measures the shaft vibration without
contact, and complies with API Standard 670. This is the most appropriate sensor to measure shaft vibration
supported by plain bearings, and is frequently used to monitor the vibration of turbine generators and
compressors. It can also be used in an explosive gas atmosphere due to its intrinsic safety construction.
