SOS method pressure gauge
Sanyu Electronics Industry Co., Ltd.
About This Product
This is a high-precision, long-term stable pressure sensor that uses silicon-on-sapphire technology and a strain gauge to measure pressure as an electrical signal. Depending on the measurement purpose, it can be connected to various measuring instruments to display, record, control, monitor pressure, etc.
Silicon-on-sapphire (SOS) technology involves growing a silicon thin film (epitaxial growth) on a sapphire (Al2O3 single crystal) substrate and processing it into a silicon semiconductor to form a strain gauge. This silicon semiconductor strain gauge and the sapphire substrate (pressure gauge diaphragm) are bonded at the atomic level, creating a highly stable pressure sensor.
■High precision
Sapphire, the material of the diaphragm, is a single crystal of aluminum oxide, and has high responsiveness and excellent linearity and hysteresis characteristics.
■High reliability
Because silicon semiconductor strain gauges are atomically bonded to a sapphire substrate, they maintain extremely stable characteristics and high reliability. The load characteristics on the negative pressure side are maintained at the same level as the positive pressure side, making it possible to measure compound pressure with high accuracy.
■High heat resistance
The sapphire substrate used in SOS technology is itself a highly insulating material, and can be used as a sensor even in high-temperature environments of 350°C.
■Hydrogen gas compatibility
Sapphire has excellent hydrogen gas compatibility, solving problems of permeation and embrittlement.
■Applications
・Hydraulic management of construction machinery
・Measurement of pressure inside pipes in narrow spaces, etc.
・Refrigerant pressure monitoring for air conditioners, etc.
・Quality control of gas filled containers
- Size, shape, specification accuracy, etc. can be adjusted depending on the application, so it is widely used as a sensor embedded in equipment.
