Noise monitoring process

Noise monitoring process noise monitoring process: acquisition by the BR-ZS1 noise monitor sub-decibel noise at the source to the value of size. By RS4855 interface transfer Cao DVR to a display via video overlay it can then be displayed on a large screen DLP. Noise Monitoring Technical parameters Measuring range: 30 ~ 130dB (A) Frequency range: 20Hz ~ 12.5kHz frequency weighting: A (weighting) Time weighting: F (fast) output interface: 4 ~ 20mA / RS485 sensitivity: voltage 41.5mV / dB; current 0.133mA / dB maximum error: 0.5dB Power: 220V mains or 24V DC Size: 200mm × 104mm × 50mm Shape Material: Aluminum alloy shell, rugged corrosion noise monitoring high degree of integration features: built-in noise probe The data acquisition module, signal conditioning modules, highly integrated integrated design to ensure undistorted noise signal is converted to the scene decibels and displayed. Versatility: 4 ~ 20 mA industry standard output, linear conversion, compatible with the mainstream market control system and monitoring system, composed of the noise monitoring unit can also be connected with a variety of display, real-time live display for monitoring results. Real good: the ability to monitor 24 hours all-weather noise, strong data representation, to reflect the true level of noise. Adapt to the environment strong: aluminum shell design, rugged, dust, moisture, suitable for harsh industrial environments, can also be used in the field of long-term online monitoring.
