Duwei Intelligent HS series industrial grade pressure sensors cleverly utilize nano monocrystalline silicon materials and advanced MEMS microfabrication technology to construct a high-precision measurement system. Its measurement range spans a wide range, from a slight differential pressure of -100kPa to a high pressure of 40MPa, all of which can be accurately covered. The full range accuracy is controlled at ≤ 0.075% FS, and the long-term stability is maintained at ± 0.15% URL for 10 years. Such precision can stably meet the strict requirements of various complex control systems such as PLC and DCS for data acquisition.
