DMP305X-DST Single-Crystal Silicon Differential Pressure Transmitter Delivers Breakthrough Measurement Performance in RTO Applications
Leveraging next-generation single-crystal silicon sensing technology, the DMP305X-DST differential pressure transmitter achieves revolutionary measurement capabilities in Regenerative Thermal Oxidizer (RTO) systems. The transmitter incorporates a third-generation single-crystal silicon piezoresistive sensor, delivering exceptional 0.05% FS accuracy and ±0.01% FS/year long-term stability - perfectly suited for precise monitoring of micro-pressure differentials (0-2.5kPa) between combustion chambers and regenerative chambers in RTO processes. Its proprietary temperature self-compensation algorithm maintains measurement accuracy across an ambient temperature range of -40 to 125°C, effectively compensating for severe temperature fluctuations during RTO switching cycles.
In operational environments, the DMP305X-DST's rapid response characteristics enable precise detection of transient pressure variations during valve switching, while integrated advanced digital filtering technology eliminates signal interference. The transmitter's bidirectional overpressure protection structure ensures long-term durability against corrosive high-temperature exhaust gases containing acidic components (SOx, NOx, etc.).
The device transmits real-time data via MODBUS or HART protocols to central control systems, enabling quantitative assessment of regenerative bed clogging status. Field applications demonstrate that RTO systems equipped with DMP305X-DST transmitters achieve 30-50% extension in regenerative bed replacement cycles while maintaining stable VOC treatment efficiency. The modular design supports hot-swappable maintenance, significantly enhancing RTO system operational reliability and serviceability.
