Gas detector DG-PV4E2 ammonia (selective - wastewater treatment plants), 100ppm, electrochemical sensor

Gas detectors DG/PV – reliable safety in industry

The DG/PV series measurement detectors are devices designed for continuous monitoring of toxic and explosive gas concentrations in industrial and enclosed spaces. They are used wherever safe working conditions and health protection are necessary. The DG-PV4E2 model, equipped with a selective electrochemical sensor, is dedicated to precise ammonia measurement, especially in wastewater treatment plants. The device is characterized by high accuracy and reliability, confirmed by calibration in an accredited GAZEX laboratory (in accordance with PN-EN ISO/IEC 17025 standard).

Construction and functionality

DG/PV detectors are distinguished by a modular design, allowing for easy replacement of the sensor module. This translates to lower operating costs and faster response in the event of a failure or the need for calibration. The device has two signal outputs – current 4-20mA (active) and voltage 2-10V – which ensures compatibility with various central gas monitoring systems. Built-in optical signaling (two LEDs) informs about exceeding permissible norms, failures and the need for calibration. Additionally, the detector has a thermal compensation circuit, minimizing the impact of ambient temperature changes on measurement accuracy.

Applications and benefits

• Ammonia concentration monitoring: A specialized sensor allows for precise measurement of ammonia in wastewater treatment plants, ensuring the safety of employees and optimizing technological processes.
• Versatility: Possibility of cooperation with central units of various manufacturers thanks to standard signal outputs.
• Easy maintenance: Replaceable sensor module facilitates servicing and calibration of the device.
• Durable construction: Splash-proof housing (IP44) provides resistance to harsh environmental conditions. Possibility of additional protection with mechanical guard AR-1d.
• High accuracy: Calibration in an accredited GAZEX laboratory guarantees the reliability of measurements.
• Alarm signaling: Built-in optical signaling informs about exceeding permissible gas concentrations and potential failures.
• Temperature compensation: Thermal compensation circuit ensures stable readings even under changing environmental conditions.

The DG-PV4E2 detector is a solid and reliable solution for installers and end-users looking for an effective ammonia concentration monitoring system in demanding industrial conditions. The device is easy to install and operate, and its modular design minimizes operating and maintenance costs. However, let us remember that DG/PV detectors are not intended for use in areas at risk of explosion of gases, vapors or dust – these are devices of conventional construction.
