Hydrocarbon gas detectors – reliable protection for installations

The DEX-1KL/N-HT gas detector is an advanced device designed for continuous monitoring of flammable gas concentrations, especially hydrocarbons, with the possibility of calibration for methane in the range of 10-30% LEL or on request. It utilizes a proven catalytic gas sensor technology, ensuring fast and precise detection of potential hazards. The device is particularly useful in places where there is a risk of leakage of natural gas, propane-butane or other flammable substances.

Design and application

The detector is designed to operate in harsh industrial conditions, making it suitable for both industrial installations and residential and commercial buildings. The F4-HT-C version with a high-temperature version up to +80°C allows mounting in places exposed to elevated temperatures. The housing is available in aluminum version or, on request, in brass – allowing the device to be adapted to specific environmental requirements. The detector works with GAZEX MD-1.A/T, MD-1, MD-2, MD-4 and measurement-threshold modules MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8 and MDP-16 control modules.

Advantages and benefits

• High sensitivity and selectivity: The catalytic sensor provides precise detection of flammable gases, minimizing the risk of false alarms.
• Resistance to external conditions: High-temperature execution (up to +80°C) and the possibility of choosing a housing (aluminum or brass) ensure reliable operation in difficult conditions.
• Versatility: The ability to calibrate for methane (10/30% LEL) or on request for other flammable gases increases the range of applications.
• Compliance with standards: The detector meets the requirements of the ATEX Directive, which guarantees safety of use in potentially explosive areas.
• Easy integration: Compatibility with GAZEX control modules facilitates integration with existing signaling and alarm systems.
• Replaceable sensors: Ensure long-term operation of the device and minimize maintenance costs.
• Calibration: Detectors are calibrated in their own GAZEX Calibration Laboratory accredited according to PN-EN ISO/IEC 17025.

Additional information

Thanks to the modular design of the detector, it is possible to replace the sensor modules without the need for calibration on site. The device is intended for cooperation with alarm modules produced by GAZEX, which provides a comprehensive solution in the field of flammable gas detection. Remember to calibrate the detector regularly according to the manufacturer's recommendations to ensure its proper operation for a long time. When working in an area threatened by gases from group IIA or IIB, a TC-DEX test gas supply cap should be used.
