Monocrystalline Silicon Pressure Transmitter

MODEL: ZNC-PT-MS

The Monocrystalline Silicon Pressure Transmitter represents the pinnacle of high-performance and high-accuracy measurement technology. Utilizing advanced monocrystalline silicon as the core sensing element, this technology achieves superior signal linearity and stability compared to traditional sensors. Its key advantages include ultra-high precision (often better than ± 0.075% FS), exceptional long-term stability with minimal drift, and outstanding temperature compensation across wide operational ranges. These characteristics make it the ideal choice for demanding applications such as high-accuracy gas/steam flow measurement (Differential Pressure type), critical parameter monitoring in the petrochemical and power industries, and any scientific research requiring high resolution and traceability.
