Gas detector DG-PV0E.NO2 NO2, 20ppm, electrochemical sensor

Gas detectors – reliable nitrogen dioxide measurement

The DG-PV0E.NO2 gas detector is a precise device designed for continuous monitoring of nitrogen dioxide (NO2) concentration in the air. It utilizes an electrochemical sensor, providing measurement accuracy up to 20 ppm. The detector is used in industrial and enclosed premises, as well as anywhere where air quality control and safety are a priority. It is compatible with various control panels and gas detection systems, offering flexibility in integration with existing infrastructure.

Functionality and construction

The DG-PV0E.NO2 device is characterized by an active current output of 4-20mA and a voltage output of 2-10V, which facilitates integration with control and monitoring systems. Built-in optical signaling (with two LEDs) informs about exceeding permissible gas concentration levels, power supply problems, or the need for calibration. Additionally, the detector has a thermal compensation circuit that minimizes the impact of ambient temperature changes on measurement accuracy.

The detector's construction is designed for easy installation and maintenance. A replaceable sensor module allows for quick replacement of a damaged sensor without the need to replace the entire device. A splash-proof sensor cover (IP44 in the recommended mounting position) protects against moisture and contamination. The possibility of mounting an additional mechanical cover AR-1d increases resistance to damage in harsh industrial conditions.

• Replaceable sensor: Quick and easy replacement of a damaged element without the need to replace the entire detector – reduces operating costs.
• Two outputs: Current (4-20mA) and voltage (2-10V) ensure compatibility with various control and monitoring systems.
• Optical signaling: Two LEDs inform about the device status and exceeding alarm concentration thresholds – quick reaction to potential hazards.
• Thermal compensation: Ensures stable and accurate measurements regardless of ambient temperature – reliable data even in variable working conditions.
• Calibration: All detectors are calibrated in the accredited GAZEX laboratory (PN-EN ISO/IEC 17025 standard), which guarantees their accuracy and compliance with applicable standards.

Application and compliance

The DG-PV0E.NO2 detector is an ideal solution for monitoring nitrogen dioxide concentration in:

• Chemical industry
• Laboratories
• Boiler rooms
• Automotive workshops
• Underground garages
• Ventilation systems

Please note that DG/PV detectors are not intended for use in areas hazardous due to the explosion of gases, vapors or dusts – these are devices of conventional construction. It is also important not to use them with MDP, MDA or MDD modules. The device requires a 24V= power supply and its dimensions are 110 x 140 x 55 mm.
