Product Features
Adopting diffusion silicon sensors with oil filled welded sealing diaphragm structure, multiple process connection methods, and special materials
membraneChip, inherently safe, explosion-proof, suitable for pressure under hygienic, clean, high temperature, low temperature, and corrosive conditions
Measurement.
working principle
Adopting micro melting technology, introducing aviation application technology, and using high-temperature glass to micro process silicon varistor strain gauges
meltOn the stainless steel isolation membrane. The glass bonding process avoids temperature, humidity, mechanical fatigue, and medium
Regarding glueWater andThe influence of materials has improved the long-term stability performance of sensors in industrial environments, while
Also avoidingNo sensors requiredThe P-N junction effect phenomenon that occurs in traditional micro machining manufacturing processes.
