Anti tamper seal for ensuring that the seals on hydrocarbon tankers have not been broken

摘要

A contact (1) is made through the dust covers to each compartment's coupling (4) and when the seal is broken, a computer records the electronic signal generated by the absence of contact so the information cannot be erased. In addition, the signal is indicated on a light panel (13).- DETAILED DESCRIPTION - Device for sealing the compartments of tanks for transporting hydrocarbons, where each compartment is connected at the bottom to its respective pipework terminating in standard couplings closed by covers. The different couplings (4) to each compartment (6) for filling and emptying the tank (7) are supplied with contact detectors (1) which pass through the dust covers (2) and establish the seal by pressurizing the internal valve in the respective coupling. The electronic signal is taken from the base of the connection to the high level and/or low level detectors. The control operates via a programmable logic computer which allows the information to be stored and controlled in such a way that it is inviolable to any external manipulation
