CE Certification AKS Glass Micro-fused Silicon Technology Pressure Sensor Pressure Transmitter Manufacturers, Factories

Micro-fused silicon technology pressure sensor is also called micro-fused or glass micro-melting pressure sensor. It uses high-temperature glass powder as the packaging medium to combine the silicon strain gauge and the stainless steel diaphragm into one structure through high-temperature sintering. This technology can realize the conversion from pressure to electrical quantity output.

The Glass Micro-fused Silicon Pressure Sensor employs micro-fusion technology, incorporating aerospace application techniques. It is the core component for the manufacture of pressure sensors and pressure transmitters. As high-performance and shock resistant pressure sensitive component, it can be easily amplified and assembled into the pressure transmitters with standard signal output.
