The compact pressure transmitter adopts imported diffused silicon or ceramic piezoresistive sensor as the pressure detection element, adopts micro-melting technology, and uses high-temperature glass to melt the micro-machined silicon varistor on the stainless steel diaphragm.The glass bonding process avoids the influence of temperature, humidity, mechanical fatigue and media on the glue and materials, thereby improving the long-term stability of the sensor in an industrial environment.Because of its small size, it is called a compact pressure transmitter.
