Product introduction The imported diffused silicon piezoresistive sensor is used as the pressure detection element, and the micromachined silicon varistor is melted on the stainless steel diaphragm by using high temperature glass. The glass bonding process avoids the influence of temperature, humidity, mechanical fatigue and medium on the glue and material, thus improving the long-term stability of the sensor in the industrial environment. | ||||||||
