Description

The Renke RS-ZS-N01-2-EX is a professional-grade sound level sensor engineered for continuous environmental and industrial noise monitoring. It utilizes a high-sensitivity, pre-polarized condenser microphone paired with precision signal conditioning circuitry to deliver stable, accurate decibel readings across a broad 20Hz to 12.5kHz frequency spectrum. The sensor’s robust, wall-mount design incorporates a sealed, high-density waterproof shell that protects the internal electronics from moisture and dust, making it suitable for long-term outdoor deployment.

This sensor provides flexible integration options through its configurable output. Users can select between digital RS485 Modbus RTU communication for networked multi-drop installations or standard analog outputs (4-20mA, 0-5V, or 0-10V) for direct connection to PLC analog input modules, data acquisition systems, or standalone controllers. With a wide operating voltage range of 10-30V DC and a fast response time of ≤3 seconds, it is designed for reliable performance in diverse applications from factory floor machine monitoring to community noise assessment.

Key Features

  • High-precision condenser microphone with stable signal and excellent linearity across the full measurement range.
  • Configurable dual-mode output: Digital RS485 Modbus and selectable analog (4-20mA, 0-5V, 0-10V).
  • IP-rated, waterproof construction with internal sealing strip for superior moisture and dust protection.
  • Wide operating temperature range from -20°C to +60°C and 0-95% RH (non-condensing).
  • Fast response time (≤3s) and high resolution (0.1dB) for real-time noise level tracking.
  • Low power consumption design (max 0.4W) compatible with standard 12V/24V industrial power supplies.
  • Wall-mounted installation with simple wiring for quick deployment in field applications.

Applications

  • Industrial plant and machinery noise monitoring for occupational health and safety compliance.
  • Community and environmental noise level assessment near highways, construction sites, and airports.
  • Continuous sound level monitoring in HVAC systems, power generation facilities, and manufacturing lines.
  • Integration into smart city and building management systems for noise pollution control.
  • Noise data logging for industrial hygiene studies and labor protection regulations.

Frequently Asked Questions

What are the available output signals from this noise sensor?

The Renke RS-ZS-N01-2-EX provides flexible output options. It supports digital communication via RS485 Modbus RTU protocol for networked systems. Alternatively, it can be configured to output standard industrial analog signals: a 4-20mA current loop, 0-5V DC, or 0-10V DC voltage signal, allowing direct connection to PLC analog input modules or data loggers.

Is this sensor suitable for long-term outdoor installation?

Yes, it is designed for outdoor durability. The sensor features a high-density, waterproof shell with internal sealing strips to protect the circuitry from moisture and dust. It operates reliably within a temperature range of -20°C to +60°C and up to 95% relative humidity (non-condensing), making it ideal for continuous environmental noise monitoring.

How do I power and communicate with this sensor using RS485?

Power the sensor with a 10-30V DC supply connected to the designated power terminals. For RS485 communication, connect the A (D+) and B (D-) data lines to your RS485 network master or converter. Ensure proper termination and unique node addresses if using multiple sensors on the same bus. Refer to the datasheet for the specific Modbus register map for reading decibel values.

What is the measurement accuracy and how is it defined?

The sensor offers a high accuracy of ±0.5 dB. This specification is defined under standard reference conditions at a sound pressure level of 94 dB and a frequency of 1 kHz. The accuracy holds across its entire 30 dB to 120 dB measurement range, with a fine resolution of 0.1 dB for detailed monitoring.
