Gas detector DG-PV4E1-Nstd ammonia, measurement range on request, from -40 °C, electrochemical sensor DG-PV4E1-NSTD

Ammonia gas detector – reliable protection and precise measurement

The DG-PV4E1-Nstd gas detector is an advanced device designed for continuous monitoring of ammonia concentration in the air. It utilizes an electrochemical sensor, providing high accuracy and sensitivity of measurements. This detector finds application in a wide range of industrial facilities, such as chemical plants, agricultural facilities, cold storage facilities, wastewater treatment plants, and warehouses, where there is a risk of ammonia leakage. The device is compatible with various gas detection control panels, offering flexibility in integration with existing safety systems.

Functionality and operating parameters

The DG-PV4E1-Nstd detector is characterized by two independent outputs – current 4-20 mA and voltage 2-10 V, which facilitates connection to control and alarm systems. Built-in optical signaling (two LED lamps) informs about exceeding the permissible ammonia concentration levels and the technical condition of the device. Additionally, the detector has a function to monitor the sensor operating time and failure history, which facilitates planning inspections and maintenance. Thermal compensation ensures stable readings even under changing environmental conditions. The device is adapted to work in difficult conditions – splash-proof housing (IP44 in the recommended mounting position) protects against moisture and dust. The possibility of mounting an additional mechanical guard AR-1d increases resistance to damage in places exposed to vandalism or accidental impacts.

Key features and benefits

• Replaceable sensor: enables quick replacement of a damaged or worn sensor without the need to replace the entire detector – reducing operating costs.
• Two signal outputs (4-20 mA and 2-10 V): ensures compatibility with a wide range of control and alarm systems.
• Built-in optical signaling: immediate information about exceeding the permissible gas concentration levels.
• Wide measurement range: ability to monitor ammonia concentration in the range of 0 ÷ 100 ppm.
• Thermal compensation: accurate measurements regardless of ambient temperature.
• Expandability: option to mount a mechanical guard or a duct housing adapts the detector to specific installation conditions.
• Calibration: all detectors are calibrated in their own GAZEX Accredited Calibration Laboratory according to PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), which guarantees the reliability of measurements.
• Operation at low temperatures: possibility of operation even at a temperature of -40°C (for DG-PV4E1).

The DG-PV4E1-Nstd detector is a reliable tool for installers of gas detection systems and end-users looking for an effective solution to monitor ammonia concentration and ensure safety in the workplace.
