China AKS High Accuracy Glass Microfused Pressure Sensor, 0.5% FS, for Oil & Gas, Hydraulic Systems Suppliers, Factory

The Glass to Metal Seal Pressure Sensor employs micro-fusion technology, incorporating aerospace application techniques. It utilizes high-temperature glass to fuse micro-machined silicon piezoresistive strain gauges onto a stainless steel diaphragm. This glass bonding process avoids the influence of temperature, humidity, mechanical fatigue, and the medium on the adhesive and materials, thereby improving the sensor's long-term stability in industrial environments.

This structure completely eliminates organic materials and elastic O-rings, creating unparalleled high-temperature resistance, corrosion resistance, all-solid-state properties, and long lifespan, making it the top choice for aerospace, energy and power, deep-sea exploration, and other demanding industrial applications.
