Gas detector DEX-14/N-HT-Nstd methane (selective), calibration 10/30 %LEL or on request, design F4-HT-C, high-temperature version up to +80°C, p-p sensor, aluminum housing

Gas detectors – reliable protection in demanding conditions

This gas detector is designed to detect methane (CH4) in enclosed spaces. The device signals exceeding two alarm thresholds, ensuring a quick response in case of a dangerous gas concentration. This is crucial for safety in many industrial and commercial applications.

The DEX-14/N detector stands out for its ability to operate at high temperatures, up to +80°C, making it an ideal solution for high-temperature environments where standard detectors might fail. F4-HT-C construction and the use of a semiconductor sensor (p-p) guarantee precise and reliable measurements. The aluminum housing provides durability and resistance to mechanical damage.

Application and construction features

This detector finds application wherever there is a risk of methane leakage – from industrial halls, through wastewater treatment plants, to production facilities. Thanks to its explosion-proof design (flameproof enclosure type), it can be used in potentially explosive zones (IIA, IIB or IIC), which confirms compliance with Directive ATEX 2014/34/UE.

It is worth noting the possibility of calibrating the device to a range of 10/30% LEL or on request, which allows you to adjust the detector's sensitivity to the specific needs of a given installation. Additionally, replaceable sensor modules with thermal and linear compensation algorithms ensure long-term and stable device operation. The detector is compatible with various GAZEX control modules (MD-1.A/T, MD-1, MD-2, MD-4; MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16; MDD-1, MDD-1/T, MDD-1x/T), which facilitates integration with existing safety systems.

Advantages for installers and end-users

• Wide operating temperature range: Possibility of use in difficult temperature conditions (+80°C).
• Explosion-proof design: Safe use in potentially explosive zones.
• Calibration possibility: Adjustment of sensitivity to specific application needs.
• Replaceable sensors: Low operating costs thanks to the possibility of replacing sensor modules.
• Compatibility with GAZEX systems: Easy integration with existing infrastructure.
• High measurement accuracy: Semiconductor sensor ensures precise methane detection.
• Durable aluminum housing: Resistance to mechanical damage and corrosion.
• PCA accreditation: Confirmation of quality and measurement reliability thanks to calibration in the GAZEX Calibrating Laboratory accredited by PCA (No. AP150).

The device is characterized by small dimensions (105 x 103 x 54 mm) which facilitates mounting even in tight spaces. Remember to use appropriate connection cable with parameters compliant with safety standards – especially in the high-temperature F4-HT… version, the coating should withstand a temperature of at least 100°C and the wire insulation at least 110°C.
