Sulfur Dioxide SO2 2000 ppm

Product catalog summary

Product Overview
The FLOWEVO Infrared Gas Sensor for Sulfur Dioxide (SO2) is designed for applications such as emission monitoring, process control, lab analysis, and environmental analysis. It features a compact design, pre-calibration, and supports Modbus ASCII or RTU communication. The sensor operates with a supply voltage of 3.3–6 V DC and indicates status via an LED.

Specifications

Measurement Principle: Non-Dispersive Infra-Red (NDIR), dual wavelength
Measurement Range: 0 to 2000 ppm Full Scale (FS)
Flow Rate: 0.1 to 1.0 l/min
Mounting Dimensions: 156 mm x 30 mm x 50 mm
Warm-up Time: Less than 2 minutes for start-up, less than 30 minutes for full specification

Measuring Response

Digital Resolution: 1 ppm
Response Time: t90 ≤ 11.6 s, ton ≤ 15.9 s at 0.7 l/min
Detection Limit: ≤ 12 ppm
Repeatability: ≤ ± 15 ppm
Linearity Error: ≤ ± 20 ppm
Long Term Stability: Zero ≤ ± 90 ppm, Span ≤ ± 110 ppm over 1000 hours

Environmental and Electrical Parameters

Operating Temperature: 0 to +50 °C
Storage Temperature: -20 to +60 °C
Air Pressure: 800 to 1150 hPa
Humidity: 0 to 95% relative humidity (non-condensing)
Supply Voltage: 3.3 V to 6.0 VDC
Power Consumption: < 800 mW

Additional Information
The sensor requires a stable, particle-free, and clean sample gas with a dew point below +5°C. Calibration is recommended at first initiation and periodically thereafter. The product is made in Germany and all specifications are subject to change without notice.
