Exhaust flow rate vacuum sensor |
摘要 |
A vacuum sensor for use in devices for the vacuum packaging of perishable items. The vacuum sensor senses fluid pulses or flow expelled from an exhaust port of a pump of the vacuum packaging device. The sensor converts a force of the fluid pulses or flow into a signal that changes with a change in the force of the fluid pulses or flow. The signal is then communicated to a control circuit which uses the signal to display the progress of the vacuum process and/or shut down the pump upon establishing a substantial vacuum within the package. |
