Simtronics specializes in high-reliability fixed gas and flame detection for oil & gas, petrochemical, LNG, marine, and heavy industry. The flagship GD10 infrared hydrocarbon line—incl. the GD10-P (e.g., GD10-P00-17DG-0XH-00)—uses a solid-state IR source and heated optics to deliver very long life, fast response, and drift-free stability with minimal maintenance. Typical features include 0–100% LEL measurement, 4–20 mA (sink/source) with optional HART/relays/Modbus, 316L stainless housings, and ATEX/IECEx/CSA hazardous-area approvals, making them ideal for offshore platforms, gas plants, compressor stations, and tank farms.
