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.

Method of and system for electrically processing vacuum pressure

In a vacuum unit which can electrically process information, a vacuum pressure value is detected by a detecting device and a desired pressure value is set by a setting device. The so-set desired pressure value is digitally displayed on a displaying device and stored in a storing device. The set desired pressure value is compared with the detected vacuum pressure value by a determining device. When the result of comparison is brought to a given value, it is determined that an unusual or improper state has been developed. When the set desired pressure value and the detected vacuum pressure value coincide with each other in a predetermined range, a predetermined signal is produced from an output device. The displaying device is provided with an adjusting device capable of adjusting the state of visual recognition of each pressure value.

Pressure information processing system suitable for use in a vacuum unit

A method and an apparatus for electrically processing vacuum pressure information in a vacuum unit. The apparatus basically comprises a vacuum supply mechanism, a detecting device, a determining device, a failure precognition signal generating device and a pressure setting-up device. In the apparatus, pressure values are first detected, and a desired pressure value lower than the maximum pressure value of the detected pressure values is digitally displayed on a display unit. Then, the desired pressure value is stored in a storage unit, and pressure values relative to vacuum, which are detected from the detecting device held in front of a passage which communicates with a vacuum port, are converted into digital signals. Thereafter, the digital signals thus converted are digitally displayed on the display unit. Further, the desired pressure value stored in the storage unit is compared with each of the detected pressure values. When they coincide with each other within a predetermined range, a predetermined signal is generated.
