Gas detector DEX-P7E/N hydrogen, 1000ppm, P4-C design, electrochemical sensor, brass housing

Gas detectors – reliable protection for installations

The DEX/P series detectors are devices designed for continuous monitoring of gas or liquid vapor concentrations in enclosed spaces. Equipped with an analog 4-20mA current output, they are an integral part of detection and alarm systems, ensuring a rapid response in the event of exceeding permissible levels. These detectors find application in a wide spectrum of industrial, commercial and public utility facilities where safety is a priority.

Construction and application

The DEX-P7E/N detector is designed to detect hydrogen in a measurement range of up to 1000 ppm. P4-C execution with a brass housing provides high resistance to corrosion and mechanical damage, guaranteeing long-term and reliable operation even in harsh environmental conditions. The electrochemical sensor is characterized by high selectivity and measurement accuracy, minimizing the risk of false alarms. The device complies with the requirements of the ATEX Directive, allowing its safe use in potentially explosive areas.

Advantages and benefits

• High measurement accuracy: The electrochemical sensor provides accurate and reliable hydrogen concentration readings.
• Durable construction: The brass housing protects the device against mechanical damage and corrosion.
• ATEX compliance: Possibility of use in potentially explosive atmospheres.
• Easy integration: Standard 4-20mA analog output allows connection to various control and alarm systems (MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16; MDD-1, MDD-1/T, MDD-1x/T).
• Replaceable sensor: Allows quick replacement of a damaged element without the need to replace the entire detector – reduces operating costs.
• Calibration: Each detector is factory calibrated in the GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation no. AP150), which guarantees its correct operation.
• Explosion-proof construction: The detector has an explosion-proof construction of a flameproof enclosure type and can be used in zones 1 or 2 hazardous with explosions of gases or flammable vapors classified into explosiveness group IIA, IIB or IIC.

The DEX-P7E/N detector is an investment in safety and peace of mind – both for installers responsible for proper installation and configuration of the system, and for end-users benefiting from the protected installation. This device is a key element of gas detection systems, ensuring a rapid response to potential hazards and minimizing the risk of serious consequences.
