The high accuracy pressure sensor is optimized for automatic industrial applications, capable of connections of all types of pressure data collection instruments and control devices such as PLC. The high-precision electronic pressure sensor gauge additionally optimizes a temperature compensation circuit and a signal processing circuit, so this high-pressure sensor gauge has an accuracy of 0.25% in the range of 0-60 bar and 0.1% accuracy at 0-20 bar. At present, this high-pressure sensor uses an oil-filled silicon core at a precise durable application.
