Gas detector WG-7KL3.Fx/A WG-7KL3.FX/A

Gas detectors – reliable safety in any environment

The WG-7KL3.Fx/A gas detector is an autonomous device designed for continuous monitoring of hydrogen (H2) concentration in the air. It finds application in places where there is a risk of gas leakage, such as garages, vehicle inspection stations, boiler rooms, engine rooms, or cold storage rooms. Its task is to detect dangerous concentrations early and alert users, allowing for a quick response and prevention of potential hazards. The device is particularly useful where reliability and measurement accuracy are required.

Construction and functionality

The WG-7KL3.Fx/A detector is distinguished by its compact, one-piece construction, integrating a sensor, control unit, audible alarm siren, LED indicator light, and relay outputs. This design simplifies installation and ensures reliable operation. The replaceable, intelligent gas sensor allows for quick replacement in case of failure or the need for calibration. The device has three alarm thresholds set by the manufacturer, ensuring precise response to changes in hydrogen concentration. Additionally, the built-in event history allows for analysis of detector operation and identification of potential problems.

It is worth noting a few key features:

• Built-in signaling: both optical (multicolor LED) and acoustic (sounder).
• Relay outputs: three separate NO outputs (including one configurable), allowing integration with external alarm systems or ventilation control.
• 24 V= power supply: ensures compatibility with various power sources.
• Thermal compensation: the thermal compensation circuit minimizes the impact of ambient temperature changes on measurement accuracy.
• Splash-proof housing (IP44): protects the device from moisture and ensures its durability in harsh working conditions.
• Testability: easy testing of the detector's functionality both externally and internally.

Application and technical parameters

The WG-7KL3.Fx/A detector is an ideal solution for security system installers and end-users looking for a reliable way to monitor hydrogen concentration. Thanks to its versatility, it can be used in various industrial and commercial facilities – from underground car parks to boiler rooms and engine rooms. The device meets all necessary safety standards and provides effective protection against hazards associated with the presence of hydrogen in the air.

The main technical parameters include: 24 V= supply voltage and dimensions of 110 x 140 x 55 mm. The catalytic sensor reacts to hydrogen concentrations in the range of 10/30/(50)%LEL (Lower Explosive Limit). It is important to remember to calibrate the sensor regularly according to the manufacturer's recommendations to ensure its proper operation and measurement accuracy.
