APT Key Features The sensor design is based on ceramic capacitor structure. All signal processing circuits are gathered together as one application-specific integrated circuit. Allowable for a wider temperature range (-40¢FXC to +135¢FXC ). Allowable pressure range is up to 3,000psi. Precise assembly process; no further adjustment is required after leaving factory. Absolute or relative pressure sensor. A reliable package type especially designed for engine and chassis installation. Accurate and stable output signal. Able to fit for all auto pressure liquids. Able to enhance the temperature output. APT Operation Principle
