GENERALWN100 is a battery operated wireless sound level meter designed as a fi eld device used under harsh environment or explosive atmosphere, and it is suitable for measurement of large sound at noisy area such as an offshore platform or a process plant to protect workers from noise exposure.In combination with the noise map software WN30 which is also provided by Yokogawa, WN100 enables to create a dynamic online noise map.The wireless communication is compliant with ISA100.11a protocol specifi cations.

FEATURES● Sound Level Measurement and Spectral

AnalysisWN100 measures three frequency-weighted sound level parameters (LAeq,T, LCeq,T, LCpeak) in accordance with IEC61672.Spectral analysis is provided as 1/3 octave band data.LAeq,T, LCeq,T , LCpeak and 1/3 octave band data are transmitted to the host system with wireless communication.

● Long Life Battery OperationWN100 can continuously measure sound level for 2 years without replacing batteries.

● Antivibration stageDedicated antivibration stage improves low level sound measurement by reducing a mechanical vibration effect from an installation environment.
