The pressure used strain silicon technology and traditional metal strain gauge principle, the new technology uses silicon strain gauges and temperature sintering process, making the pressure sensor sensitivity increased more than five times, and then with a proprietary digital amplifier and digital temperature compensation circuit, the electrical characteristics of the sensor , temperature characteristics and long-term stability is guaranteed. Sensor interface and housings are made of stainless steel, with good corrosion resistance. This product can be widely used in industrial, aviation, aerospace, automotive, medical and other fields of refrigeration.
