Abstract: There is disclosed apparatus for measuring multiple pressures within different pressure ranges. The apparatus contains multiple pressure sensors which are positioned on a housing, where each pressure sensor is adapted to measure pressure within a different pressure range. The housing has an input port which is constructed to communicate with different output ports, where the output ports communicate with each different pressure sensor utilized in a different pressure range. The input port has a stepped or keyed aperture which is adapted to receive different pressure adapters to assure that, for example, only a high pressure will be applied to the high pressure sensor during high pressure measurements. By selecting another adapter, a mid-range pressure and a high pressure will be applied to the pressure sensors during the measurement of a mid-range pressure. By receiving a different adapter, a low pressure will be applied to all the pressure sensors during low pressure measurement.
