This Standard covers analog, dial-type gauges, which, using elastic elements, mechanically sense pressure and indicate it by means of a pointer moving over a graduated scale. It also includes the following attachments installed between the pressure source and gauge(s): diaphragm seals, snubbers, and pressure limiting valves. This Standard does not include gauges of special configuration designed for specific applications, edge reading, deadweight or piston gauges, other gauges not using an elastic element to sense pressure, diaphragm actuated pressure instruments that employ mechanical linkages to transmit the applied pressure, other attachments such as siphons, electric contacts, and gauge isolation valves or other separation devices designed to protect the pressure element assembly.<\/p>\n
