1) How does a combination gauge work? A combination gauge contains two sensing elements inside one instrument: Pressure: a Bourdon tube flexes with pressure and turns the pressure pointer across a bar/psi scale. Temperature: either a bimetal coil (expands with heat)...
What is a Combination Gauge? A combination pressure–temperature gauge is a single instrument that shows pressure (bar/psi) and temperature (°C/°F) on one dial. It uses two independent sensing elements—typically a Bourdon tube for pressure and a bimetal or gas-actuated...
