Engineered with a NEMA 4X-rated cylindrical enclosure (178mm diameter × 180mm length), the GE HYDRAN 201Ti withstands extreme temperatures (-40°C to +80°C) and harsh environments, including offshore platforms and utility-scale power plants. Its no-moving-parts design eliminates maintenance-intensive components like pumps or filters, while the vacuum-resistant gas extraction membrane ensures continuous, reliable gas sampling directly from the transformer oil valve 813. The device features a composite gas sensor that responds 100% to hydrogen and is sensitive to CO, C₂H₂, and ethylene, aligning with IEEE C57.104 standards for DGA interpretation 210.
With a backlit LCD display and RS-485 Modbus connectivity, the GE HYDRAN 201Ti allows remote monitoring of gas trends, configurable alarm thresholds, and self-diagnostics. It supports both Hydran proprietary protocols and Modbus RTU, enabling integration with SCADA systems or GE’s Perception™ software for centralized data analysis 810.
