Gas detector DEX-P7E/N – reliable explosion protection

The DEX-P7E/N gas detector is an advanced device designed for continuous monitoring of hydrogen concentration in the air. It utilizes an electrochemical sensor, providing precise measurement in the range up to 1000 ppm. The explosion-proof design, with a brass housing, guarantees safe operation in potentially hazardous environments. The detector is powered by the system and equipped with a standard 4-20mA analog output, enabling easy integration with existing control and alarm systems.

Construction and application

Detectors of the DEX/P series, including the DEX-P7E/N model, find application in a wide spectrum of industries where there is a risk of explosion or fire caused by the presence of gases. These devices are ideal for monitoring in enclosed spaces, such as:

• Chemical and petrochemical industry
• Power plants and energy facilities
• Automotive workshops and air conditioning service centers (especially when working with batteries)
• Warehouses and storage of flammable materials
• Laboratories and research facilities

Thanks to ATEX certification, the detector can be used in explosion-hazardous zones of varying degrees of risk (zone 1 and 2). The brass housing provides high resistance to corrosion and mechanical damage, which translates into a long service life.

Key features and benefits

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