Gas detector DG-P7E/N-Nstd hydrogen, measurement range on request, electrochemical sensor DG-P7E/N-NSTD

Gas detectors – reliable safety in any environment

This stationary, measuring gas detector DG-P7E/N from Gazex is designed for continuous monitoring of hydrogen presence in industrial and enclosed spaces. The device signals exceeding permissible concentrations, ensuring the safety of people and protecting against potential hazards. This detector is a key element of gas detection systems, cooperating with control modules or alarm centers.

Construction and principle of operation

The DG-P7E/N detector uses an electrochemical sensor to precisely measure hydrogen concentration in the range of 0-1000 ppm. The measurement signal is transmitted in the 4-20 mA standard, allowing easy integration with existing monitoring and control systems. Built-in optical signaling informs about the alarm directly on the device. The modular design of the detector allows replacing a damaged sensor without having to replace the entire device, which reduces operating costs. Replaceable sensor modules have thermal and linear compensation algorithms, ensuring measurement accuracy even in changing environmental conditions.

Application and benefits

The DG-P7E/N detector finds application in many industries where there is a risk of hydrogen leakage, such as:

• Chemical industry: Monitoring production processes involving hydrogen.

• Power plants: Detecting hydrogen leaks from energy production installations.

• Warehouses: Controlling hydrogen concentration in rooms storing batteries or other materials generating hydrogen during charging.

• Laboratories: Safety during experiments with hydrogen.

• Workshops: Controlling hydrogen concentration during welding or other technological processes.

The use of this detector is primarily:

• High measurement accuracy: The electrochemical sensor provides accurate and reliable hydrogen concentration measurement results.

• Easy integration: The standard 4-20 mA signal allows connection to various control and monitoring systems.

• Low operating costs: Replaceable sensors allow extending the device's lifespan without having to replace it.

• Simple installation and operation: The modular design facilitates installation and servicing of the detector.

• Certification: Gazex detectors are calibrated in an accredited laboratory in accordance with the PN-EN ISO/IEC 17025 standard, which guarantees their reliability and measurement accuracy.

The device has dimensions of 110 x 140 x 55 mm, allowing easy surface mounting in various locations. Power is supplied from the system, eliminating the need for external power sources.
