MINING

High precision and high resolution, long-term stable measurement: The product resolution reaches 0.1dB, with a measurement accuracy of ±0.5dB (reference standard 94dB@1KHz). The measurement deviation is less than 2% throughout the entire service life, accurately capturing subtle noise changes. It supports an ultra-wide measurement range of 30dB~130dB, covering noise detection needs in most scenarios such as daily environments, industrial plants, and transportation hubs, with stable and reliable data. Dual output modes are selectable, seamlessly adapting to all types of industrial control systems. It supports both analog and digital output modes. The analog output provides 4-20mA current and 0-5V/0-10V voltage options, adapting to traditional industrial control acquisition systems. The RS485 output adopts the industrial-grade ModBus-RTU protocol with standard N81 communication parameters, seamlessly connecting to PLCs, DCSs, data acquisition terminals, and IoT platforms. Integration and development are convenient, requiring no complex debugging. Low-power, wide-voltage design, adaptable to complex industrial power supply scenarios. Utilizing a 10~30V DC wide-voltage power supply, it can directly adapt to most power supply systems in industrial sites without the need for additional conversion modules. The maximum power consumption of the entire unit is no more than 0.18W, and the standby power consumption for 485 communication is only 0.1W. This ultra-low energy consumption design significantly reduces the pressure on on-site power supply, making it particularly suitable for unattended monitoring projects that operate continuously for extended periods, effectively reducing maintenance costs. Wide-band response + ultra-fast response, accurately reproducing the true characteristics of noise. The frequency response range covers 20Hz~12.5KHz, fully covering the entire frequency band of noise that the human ear is sensitive to, accurately reproducing the true characteristics of environmental noise. With a response time of ≤3S, it can quickly capture instantaneous noise changes, perfectly adapting to scenarios with high real-time requirements such as factory safety early warning, construction site dust and noise monitoring, and computer room equipment abnormality monitoring. Industrial-grade environmental adaptability and strong load capacity ensure stable operation in a wide temperature range of -20℃ to 60℃ and a high humidity environment of 0~95% RH (non-condensing), making it suitable for complex and harsh operating environments such as industrial sites and outdoor monitoring stations. It has excellent load capacity, with a voltage output impedance of ≤250Ω and a maximum current output impedance of up to 600Ω, supporting long-distance signal transmission with low signal attenuation and strong anti-interference ability., Manufacturer: MINING
