SDT-FUSENSDBA2噪声传感器

Description:

The SDT A-weighted sound pressure measurement microphone is to be used in combination with the SDT 170 M and SDT 170 MD Multifunction Ultrasonic Detectors. The Ultrawave 170 senses the presence of the dBA sensor and automatically changes to the appropriate setting, scales and units. Measurements can be time-dated and logged inside the memory of the SDT 170 M and SDT 170 MD versions. Refer to the SDT 170 documentation for data logging limits and possibilities.

Applications:

Monitoring and Data Logging noise levels in the plant. Tie data into central maintenance database.
