Abstract
A pressure gauge includes a housing, a helical tube, and a compensation member. The housing has an inlet. The helical tube is arranged within the housing and has a closed end and an open end, the open end of the helical tube in fluid communication with the inlet. The compensation member is arranged between the between the open end and the closed end of the helical tube, the compensation member fixed to the helical tube. The compensation member and the helical tube are formed from materials having different coefficients of thermal expansion to limit movement of the closed end of the helical tube due to temperature change of a compressed fluid in fluid communication with the helical tube. Pressure vessel assemblies and methods of displaying pressure in pressure vessels are also described.
