Description

The SN-300FL-ZS-N01 Long Rod Noise Sensor employs a high-sensitivity condenser microphone and advanced signal conditioning circuitry to deliver accurate sound pressure level (SPL) measurements. Its design is optimized for stable performance across a broad frequency spectrum from 20 Hz to 12.5 kHz, making it suitable for both acoustic analysis and continuous environmental noise monitoring.

Housed in a corrosion-resistant 316L stainless steel rod, the sensor is built for harsh industrial and outdoor environments. The integrated flange facilitates secure mounting on poles, walls, or machinery. The dual-output architecture allows seamless integration into modern SCADA, PLC, or microcontroller-based data acquisition systems via industry-standard Modbus protocol or direct TTL logic.

Key Features

  • High-stability condenser microphone with wide 100 dB dynamic range.
  • Dual-interface output: RS485 Modbus-RTU for industrial networks and TTL for direct microcontroller connection.
  • Engineered for long-distance, noise-immune data transmission over RS485 lines.
  • Low power consumption (max 0.1W) for energy-efficient continuous operation.
  • Operates reliably across an extended temperature range from -20°C to +60°C.
  • Flange mounting design with included hardware for quick and secure installation.
  • Optimized performance-to-cost ratio for large-scale deployment in monitoring networks.

Applications

  • Industrial facility perimeter noise monitoring and compliance reporting.
  • Urban environmental noise pollution assessment and mapping networks.
  • Construction site noise level monitoring and control.
  • HVAC and mechanical equipment acoustic performance and fault diagnosis.
  • Transportation infrastructure (highways, railways, airports) noise impact studies.

Frequently Asked Questions

What communication protocols does this noise sensor support?

The sensor supports two primary communication interfaces. It features an RS485 interface using the Modbus-RTU protocol, ideal for long-distance, multi-drop industrial networks. Additionally, it provides a TTL-level serial output for direct connection to microcontrollers like Arduino, ESP32, or Raspberry Pi, offering flexibility for both industrial and prototyping applications.

What is the required power supply for the SN-300FL-ZS-N01 sensor?

The sensor operates on a wide-range DC power supply from 10V to 30V. This range makes it compatible with common 12V and 24V industrial power systems. Ensure your power source can provide clean, stable DC voltage within this range for optimal performance and accuracy.

How do I mount and install this long-rod noise sensor?

The sensor is designed for easy installation via its integrated mounting flange. Simply secure the flange to a stable surface like a pole, wall, or equipment frame using the provided screws. Ensure the microphone element is oriented correctly and has an unobstructed acoustic path to the noise source for accurate measurements.
