The core of the CXT Series high-accuracy smart transmitter adopts a unique monocrystalline silicon composite pressure sensor, an advanced integral capsule structure and the latest microprocessor technology, ensuring sensor stability and excellent performance. Basic accuracy ±0.05%FS (up to ±0.035%FS); field-proven over many years, it still achieves 0.05% accuracy after 10 years of continuous use.
The product features a rugged metal housing and highly reliable industrial-grade measuring components, with electromagnetic interference immunity and lightning protection; integrated diagnostics monitor the operating process and its own status in real time, entering an alarm state and outputting an alarm current once a set number of events is exceeded, providing control signals for system interlocking or SIS safety systems. It supports configuration via HART, PA, FF, APL and other communication protocols; the isolating diaphragm is available in various corrosion-resistant materials such as 316L, Hastelloy, tantalum, Monel 400, nickel, titanium or gold-plated 316L.
