A method of and a system for electrically processing vacuum pressure information, which is suitable for use in a vacuum unit. Pressure values are detected and a desired pressure value lower than the highest vacuum pressure value of the detected pressure values is displayed on a displaying device in digital form. The desired pressure value is stored in a storing device. Each of pressure values relative to vacuum, which are detected by a pressure detecting element held in front of a passage communicating with a vacuum port, is converted into a digital signal. The so-converted digital signal is digitally displayed on the displaying device. The desired pressure value stored in the storing device is compared with each of the detected pressure values relative to the vacuum, and information about faulty points is displayed on the displaying device based on the result of comparison.

Abstract

A method of and a system for electrically processing vacuum pressure information, which is suitable for use in a vacuum unit. Pressure values are detected and a desired pressure value lower than the highest vacuum pressure value of the detected pressure values is displayed on a displaying device in digital form. The desired pressure value is stored in a storing device. Each of pressure values relative to vacuum, which are detected by a pressure detecting element held in front of a passage communicating with a vacuum port, is converted into a digital signal. The so-converted digital signal is digitally displayed on the displaying device. The desired pressure value stored in the storing device is compared with each of the detected pressure values relative to the vacuum, and information about faulty points is displayed on the displaying device based on the result of comparison.
