Gas Leak Sensor: Reliable Detection of Combustible Gases
The HW-group Gas Leak Sensor is a highly reliable gas detector specifically designed for the detection of combustible gases such as natural gas, methane, propane, butane, acetylene, and hydrogen in server rooms, industrial facilities, and buildings. With high stability, sensitivity, and long service life, the sensor offers two adjustable response thresholds for different gas concentrations. Gas detection is indicated by optical (LED) and acoustic signals as well as a relay output, which can be connected to HW-group devices such as Poseidon2, Ares, or STE2 to enable remote monitoring via LAN, GSM, SNMP, or email. The gas leak sensor is ideal for server room monitoring and industrial monitoring to detect dangerous gas leaks early and prevent damage.
Main Features of the Gas Leak Sensor
The gas leak sensor combines precise gas detection with easy integration into monitoring systems. Here is an overview of the key features:
- Detection of Combustible Gases: The gas leak sensor detects all types of combustible gases, including natural gas, coal gas, propane, bottled gas, acetylene, and hydrogen.
- Two Response Thresholds: Two adjustable response modes based on gas concentration for flexible alarm triggering.
- Optical and Acoustic Signaling: Integrated LED indicator and acoustic alarm for immediate warning in case of gas leaks.
- Relay Output: Potential-free contact (NO/NC, max. 0.5 A at 125 V AC) for connection to alarm systems or HW-group devices such as Poseidon2.
- High Stability and Service Life: Robust construction with long operating life and high sensitivity for reliable safety detector function.
- Compatibility: Connection via digital inputs (dry contact) for seamless Poseidon2 integration into monitoring systems.
Application Areas of the Gas Leak Sensor
The gas leak sensor is versatile and suitable for scenarios where the detection of combustible gases is crucial. Typical application areas include:
- Server Rooms and Data Centers: Protection against gas leaks that could endanger equipment or infrastructure through early gas detection.
- Industrial Facilities: Monitoring of gas leaks in production halls, storage rooms, or technical areas.
- Building Management: Detection of gas leaks in heating or supply systems to ensure the safety of residents or employees.
- Remote Monitoring: Integration with Poseidon2 or Ares for real-time notifications via email, SMS, or SNMP trap when gas leaks are detected.
- Safety Detector: Use in safety-critical environments to prevent explosions or fires caused by combustible gases.
Why the Gas Leak Sensor is the Right Choice?
The gas leak sensor offers a reliable solution for the detection of combustible gases in sensitive environments. Compared to other gas detectors, it stands out due to its high sensitivity, two response thresholds, and robust construction. Integration into HW-group systems enables easy connection to existing monitoring solutions, while optical and acoustic signaling provides immediate warnings. The compact design (130 x 85 x 65 mm) and simple installation make it ideal for use in server rooms, industrial facilities, and buildings.

Integration with HW-group Products
The gas leak sensor is optimally matched to HW-group devices such as Poseidon2, Ares, STE2, or Damocles. By connecting with these devices, you can build a comprehensive safety system that reports gas leaks in real time via LAN, GSM, SNMP, or Modbus/TCP. The free HWg-PDMS software enables analysis and export of data to Excel for detailed reports. Connection to the SensDesk portal offers additional visualization options via Android or iOS apps.
Installation and Setup
Installation of the gas leak sensor is straightforward. The sensor is mounted at a suitable location, ideally near potential gas sources (e.g., heating systems or gas pipes). It operates on 12 V DC (external power supply required, not included) and is connected to the monitoring system via digital inputs (dry contact). The adjustable response thresholds allow adaptation to specific requirements, while optical and acoustic signaling provides immediate alerts.
The HW-group gas leak sensor is the ideal solution for the detection of combustible gases and remote monitoring in server rooms, industrial facilities, and buildings. With its high sensitivity, two response thresholds, and seamless integration into HW-group systems, it provides reliable protection against dangerous gas leaks.
