Features

The GPT305D series of monocrystalline silicon sensors adopts monocrystalline silicon sensor chips made of Germany's advanced MEMS technology and the world's original monocrystalline silicon double-beam suspension design, achieving world-leading high accuracy and excellent ultra-high overvoltage performance. stability. The built-in signal processing module realizes the perfect combination of static pressure and temperature compensation, providing extremely high measurement accuracy and long-term stability under a wide range of static pressure and temperature changes.

Using monocrystalline silicon piezoresistive technology, the performance is stable and the accuracy can reach 0.075%FS.
