Description

SW6-NO2-02 Industrial NO2 Sensor: Precision Monitoring for Harsh Environments

Elevate industrial safety and compliance with the SW6-NO2-02, a cutting-edge Nitrogen Dioxide (NO2) sensor designed for high-precision detection in demanding applications. Engineered to thrive in extreme conditions—from chemical plants to mining operations—this sensor combines robust durability with smart IoT integration, ensuring reliable real-time data for critical decision-making.

Why Choose the SW6-NO2-02?

I. Uncompromising Accuracy

Equipped with advanced sensing technology and imported chips, the sensor delivers precise NO2 concentration measurements (0–2000 ppm) with ±5% FS detection accuracy.

Resolutions as fine as 0.1ppm (20ppm range) ensure early detection of hazardous levels, safeguarding personnel and regulatory compliance.

II. Built Tough for Harsh Environments

IP65-rated enclosure protects against dust, rain, and snow, while withstanding temperatures from -40°C to 80°C.

Waterproof ceramic material and a built-in moisture-proof rubber strip prevent damage in humid or submerged conditions.

III. Flexible Communication & IoT Integration

Supports RS485 Modbus-RTU for wired industrial control systems and LoRaWAN for wireless transmission, enabling seamless integration into existing IoT architectures.

Dual-mode connectivity ensures cross-region data synchronization, ideal for remote monitoring in mines, factories, or urban air quality networks.

IV. Wide Power Compatibility & Low Energy Consumption

Operates on DC 9–36V power supply, adapting to diverse industrial setups while maintaining an average power consumption of just 0.18W.

V. Robust EMC Compliance

Certified to withstand electrical surges (IEC 61000-4-5), EFT (IEC 61000-4-4), and ESD (IEC 61000-2), ensuring stable performance in electrically noisy environments.

Key Features

Fast Response: ≤30 seconds for real-time monitoring.
High Stability: ≤2% signal drift per month, minimizing calibration needs.
User-Friendly Design: RS485 parameter configuration software simplifies setup; color-coded cables (black/brown for power, blue/yellow for communication) streamline installation.

Applications

Mining: Monitor underground NO2 levels to prevent worker exposure.
Chemical/Pharmaceutical Plants: Detect leaks in production lines or storage areas.
Fertilizer Manufacturing: Ensure compliance with environmental regulations.
Smart Cities: Integrate into urban air quality networks via LoRaWAN.
