Abstract
A combined fluid pressure gage and safety pressure relief device for interconnection with systems wherein excess fluid pressure will cause explosions likely to result in injury to personnel and damage to surrounding equipment. The device accurately measures fluid pressure within the system to which it is connected so long as the system pressure remains within the working range of the pressure gage. However, should the system pressure exceed the normal full scale pressure reading on the gage, the device will instantly and automatically safely vent the system to atmosphere. Once the device is vented the pressure relief mechanism must be manually reset by skilled technicians using special tools before the apparatus can be reused.
