상품 소개

The cleanroom noise level sensor combines a measurement microphone, preamplifier and digital signal processing in a wall or ceiling transmitter. Selected frequency and time weighting produce a consistent sound-level value for room trends, occupational studies or equipment-noise alarms. The microphone is protected by an acoustically transparent cap that can be inspected or replaced. Analog and digital outputs transfer the measured level without streaming room audio, preserving the function as a sound-pressure monitor rather than a recording device.

주요 기능

A calibrated measurement microphone responds predictably across the selected acoustic band.

Configurable frequency and time weighting supports different monitoring objectives.

Continuous dB output reveals gradual equipment-noise changes as well as threshold events.

The transmitter reports numeric sound level without capturing intelligible audio recordings.

응용 프로그램 솔루션

Fixed noise monitoring must distinguish meaningful changes from short impacts and must not be confused with voice recording.

Brief door impacts create repeated high-noise alarms.Appropriate time weighting and alarm delay reduce response to momentary events.

Microphone dust protection changes the acoustic response.An acoustically specified protective cap maintains airflow while shielding the element.

Staff assume the device records conversations.The output is limited to sound-level data and status rather than audio content.

A rising fan or bearing noise is noticed only after failure.Long-term dB trends reveal persistent changes relative to the established room baseline.
