Abstract:
An apparatus for simulating a predetermined burst pressure for a package burst pressure tester, comprising:a. a pressure tank having a first input port connectable to said burst pressure tester, for receiving a flow of pressurized air from said burst pressure tester; b. a second port on said pressure tank, and an electrically connected solenoid relief valve connected to said second port, said solenoid relief valve having an output port vented to atmosphere; c. a pressure switch on said pressure tank and connected to monitor the pressure inside said pressure tank, said pressure switch being settable to a predetermined pressure, and having means for generating an electrical signal when the pressure in said pressure tank equals the settable pressure; d. a presettable timer connected to said pressure switch means for generating an electrical signal, said timer having an input signal which is activated by said pressure switch electrical signal for the duration of time set into said timer, and having an output electrical signal; said timer output electrical signal connected to said solenoid relief valve; and e. a pressure sensor connected to said pressure tank and to said burst pressure tester, said pressure sensor having means for monitoring the pressure inside said pressure tank and means for signaling said monitored pressure to said burst pressure tester.
