Double-pointer air gauge calibrating bench

The utility model provides a double-pointer air gauge calibrating bench, and belongs to the technical field of automobile air gauges. The utility model mainly aims to solve the problems that a hand valve is used for adjusting the air pressure during present air gauge calibration, so the control speed is slow, the precision is low and the present air gauge calibration is not suitable for the modernized scale of production. The double-pointer air gauge calibrating bench is characterized by comprising a control system portion and an operation portion. The control system is composed of a PLC, a gas source processor air and a pressure proportioning valve. The operation portion is composed of a touch screen and a keyboard. According to the double-pointer air gauge calibrating bench, the PLC is used for controlling the air pressure proportioning valve, the output air pressure is accurate, and the double-pointer air gauge calibrating bench can be used for automatically calibrating, the automatic operation has at most six shifts which can be sequentially used for calibrating, the air pressure and the maintenance time of each shift can be freely set through the touch screen, and the double-pointer air gauge calibrating bench is particularly suitable for calibrating double-pointer air gauges and the like products in production.
