Natural Gas Leak Detector for Valve Well and Pipeline Inspection – D-CS1

D-CS1 valve well-type natural gas leak detector uses tunable laser absorption spectroscopy (TDLAS) technology. By measuring the intensity change of the laser before and after passing through the detection area, it can calculate the concentration and location of the natural gas leak. It also features monitoring functions for parameters such as ambient temperature, humidity, and pressure to compensate and correct for measurement results, reducing interference from environmental factors.

• It has strong anti-interference ability, is not affected by water vapor or other gases, and only reacts with methane.
• The sensor has a long lifespan and high stability (lifespan of over 10 years).
• It adopts wireless communication, has strong communication capabilities, and is not limited by communication distance.
• Overall IP68 waterproof design, suitable for damp and overflow-prone downhole environments.
• Intrinsically safe design, stable and reliable Applicable to Zone 1 and Zone 2 explosion hazard locations containing explosive gas mixtures of Class IIA to IIC, temperature groups T1 to T4.
• Can be connected to vibration signals for long-distance leak monitoring
• Detect water level information to determine the equipment's operating status

It is mainly used for monitoring and early warning of flammable gas leaks in urban lifeline underground pipeline networks. It can be widely used in underground valve wells and various confined spaces, such as urban gas, long-distance pipelines, integrated pipe corridors, petroleum, chemical, steel, fire protection, power, environmental protection, and pharmaceutical industries. It is suitable for Zone 1 and Zone 2 explosion hazard locations containing explosive gas mixtures of Class IIA to IIC, with temperature groups T1 to T4.
