Description

The Renke RS-SO2-N01-2-20P-JK-EX employs a premium imported electrochemical sensing element specifically tuned for sulfur dioxide detection. This principle ensures high selectivity against common interferents, providing stable and accurate long-term measurements critical for safety and compliance monitoring. The sensor’s internal signal conditioning circuitry delivers clean, linearized outputs across its selectable ranges.

Housed in an IP67-protected enclosure, the sensor is built for wall-mounted installation in demanding environments such as industrial facilities, refineries, and outdoor monitoring stations. Its wide operating temperature and humidity tolerance ensure consistent performance. The integrated microcontroller manages advanced temperature and baseline compensation, guaranteeing measurement repeatability and sensor longevity.

Key Features

  • High-end imported electrochemical SOâ‚‚ sensor cell for superior long-term stability and minimal drift.
  • Selectable full-scale ranges: 0–20 ppm (0.1 ppm resolution) and 0–2000 ppm (1 ppm resolution); custom ranges available upon request.
  • High accuracy: ±5% FS with excellent repeatability ≤2% for reliable trend analysis and alarm triggering.
  • Optional integrated OLED display provides clear, on-site real-time concentration values and status indicators.
  • Wide DC power supply range (10–30V) accommodates various industrial power rails and remote solar-powered setups.
  • Robust IP67 wall-mounted enclosure designed for harsh environments, resistant to dust and temporary water immersion.
  • Advanced digital calibration and temperature compensation algorithms ensure precise, repeatable measurements over the sensor's lifespan.
  • Fast response time: ≤45 seconds for the 0-20 ppm range, enabling timely leak detection and system response.

Applications

  • Continuous emission monitoring (CEMS) for SOâ‚‚ in power plant flue gas and refinery stacks.
  • Industrial safety systems for detecting SOâ‚‚ leaks in chemical processing, pulp/paper mills, and metal smelting facilities.
  • Environmental air quality monitoring stations for urban and industrial perimeter surveillance.
  • Laboratory fume hood and chemical storage area safety monitoring to protect personnel.
  • HVAC and building automation systems for indoor air quality control and ventilation demand triggering.

Frequently Asked Questions

What output signals does this Renke SO2 sensor support?

This sensor provides multiple configurable output options for seamless integration: RS485 digital communication using the Modbus RTU protocol, a standard 4-20mA analog current loop, and 0-5V or 0-10V analog voltage outputs. The specific interface is typically selected via internal DIP switches or configuration commands sent over RS485, allowing compatibility with PLCs, data loggers, and control systems.

How do I select between the 0-20 ppm and 0-2000 ppm measurement ranges?

The measurement range is selected through internal configuration, often via hardware DIP switches on the PCB or by sending specific Modbus commands over the RS485 interface. It is crucial to configure this before installation to match your expected concentration levels, as it affects the sensor's resolution (0.1 ppm vs. 1 ppm) and optimal performance range.

What is the recommended power supply and wiring for this sensor?

The sensor requires a DC power supply between 10 and 30 volts. For basic 2-wire 4-20mA loop operation, connect the power supply in series with the loop. For RS485 or voltage output modes, a separate power pair (V+, GND) and the signal wires are needed. Always use shielded cable for the signal lines and follow proper grounding practices to minimize electrical noise, especially in industrial environments.

Is the sensor suitable for outdoor installation?

Yes, the IP67-rated waterproof enclosure makes it suitable for outdoor and harsh environment installation. It is designed to withstand dust ingress and temporary immersion in water. For permanent outdoor use, ensure it is mounted in a location protected from direct, sustained rainfall or flooding, and within its specified operating temperature range of -20 to 50°C.

Does this sensor require calibration, and how is it performed?

Yes, periodic calibration is required to maintain specified accuracy. Initial calibration is performed at the factory. Field calibration typically involves exposing the sensor to a certified span gas of known SO2 concentration (e.g., 10 ppm for the 0-20 ppm range) and using the provided Modbus commands or a dedicated calibration tool to adjust the sensor's output. It is recommended to calibrate at least annually or as dictated by your application's compliance requirements.
