MSA IR5500 Open Path Gas Detector
An open-path gas detector for explosion-proof acquisition in Japan. It can accurately detect hydrocarbon gases at distances of up to 150 meters (path length), enabling wide-area monitoring.
The IR5500 is a long-range gas detector that uses infrared open-path technology to detect flammable hydrocarbon gases such as methane and propane in real-time with high accuracy. It has a split configuration with a transmitter and receiver, covering a wide range of up to 150 meters (path length). It can handle small leaks at the ppm level to large-scale leaks at the LEL level, making it ideal for outdoor facilities such as chemical plants, oil refineries, and LNG terminals. In addition to a fast response time of under 3 seconds, it features a fail-safe design with self-diagnosis capabilities and automatic gain control, making it resistant to rain and dirt, ensuring stable detection. It is calibrated at the factory, eliminating the need for zero calibration on-site, significantly reducing maintenance burdens after installation. It has obtained Japanese explosion-proof certification, allowing for safe use in harsh outdoor environments. Additionally, it supports Modbus RTU and HART communication, enabling easy integration with control systems. With 4-20mA analog signals, relay outputs, and LED displays, reliable status monitoring and control can be performed both on-site and in the control room.
