working principle
Adopting micro melting technology and introducing aviation application technology, using high-temperature glass to melt micro machined silicon varistor strain gauges
On the stainless steel isolation membrane. The glass bonding process avoids the effects of temperature, humidity, mechanical fatigue, and medium on the adhesive and
The influence of materials has improved the long-term stability performance of sensors in industrial environments, while also avoiding sensing
The P-N junction effect phenomenon that occurs in traditional micro machining manufacturing process engineering.
