Gas detector DG-P4E/N1 ammonia, 100ppm, from -40°C, electrochemical sensor

Gas detectors for industrial and domestic applications

The DG-P4E/N1 gas detector is a reliable device designed for continuous monitoring of ammonia presence in the air. Thanks to its wide operating temperature range, from -40°C, it performs perfectly both in demanding industrial conditions and in domestic applications such as cold storage facilities. The device uses an electrochemical sensor, providing a precise measurement of ammonia concentration up to 100 ppm.

Features and application

The DG-P4E/N1 detector is part of the DG/P series from GAZEX, designed to detect and signal the presence of harmful or dangerous gases for humans. Equipped with a 4-20 mA analog output, the detector allows easy integration with various control and monitoring systems. It can work with control units from different manufacturers, as well as with GAZEX control modules (MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16, MDD-1, MDD-1/T, MDD-1x/T). Its splash-proof housing provides protection against moisture and dust.

The detector finds application in:

• Industrial plants
• Logistics centers
• Cold storage facilities
• Wastewater treatment plants
• Public utility facilities
• Enclosed spaces threatened by ammonia emissions

Advantages and benefits

• Wide operating temperature range: from -40°C to +40°C (occasionally up to +50°C) – ensures reliable operation even in extreme conditions.
• Precise measurement: electrochemical sensor guarantees accurate determination of ammonia concentration (up to 100 ppm).
• Easy integration: 4-20 mA analog output enables connection to control and monitoring systems.
• Replaceable sensor: the ability to replace the sensor module reduces operating costs and simplifies calibration.
• Calibration: all detectors are calibrated in their own GAZEX Calibrating Laboratory accredited according to PN-EN ISO/IEC 17025.
• Modularity and simple installation: facilitates the design and installation of a gas detection system.
• Durable construction: splash-proof housing provides protection against external factors.

Design and technical parameters

The DG-P4E/N1 detector is characterized by a compact design with dimensions of 110 x 140 x 55 mm. It uses an intelligent sensor module with thermal and linear compensation algorithms and measurement history. Built-in optical signaling informs about exceeding the permissible ammonia concentrations. The device is powered by an external system. It is important to remember that this detector has a conventional construction and cannot be used in areas at risk of explosion of gases or dust.

The detector output is 4-20 mA, and the measurement range is from 0 to 100 ppm. It operates with an electrochemical sensor in a temperature range from -40°C to +40°C (occasionally up to +50°C). Its dimensions are 110 x 140 x 55 mm.

The use of high-quality components and regular calibration guarantee reliability and measurement accuracy for a long time of use. The DG-P4E/N1 detector is an investment in safety and comfort in places exposed to ammonia.
