Introduction to HTJ180 Sapphire Series Pressure Transmitter

The Sapphire series pressure sensor is a scientific research achievement obtained by the Russian Microelectronics Sensor Industry Group after conducting in-depth research on the characteristics of the strain effect on the heteroepitaxial semiconductor structure "Silicon on Sapphire" (SOS). The former Soviet Union was the first in the world to apply silicon sapphire technology to pressure sensors, and its outstanding characteristics have been proven in the field use of a large number of products. This technology has obtained patents in the Soviet Union, the United States, France, and Germany, and has now become a series of products with complete specifications. It is widely used in industries with harsh operating environments and high reliability requirements, such as aviation, aerospace, shipbuilding, power, nuclear power plants, petroleum, chemical fiber, food processing, etc.
