Part Information
Type ii portable pressure calibrators shall consist of a pressure control and measurement module and pressure intensifier in separate enclosures; and a nitrogen pressure source.Shall provide manual control, measurement and display of positive pressures for calibrating shipboard pressure instruments.Shall not contain a internal pressure source.Shall be pneumatically connected to the pressure intensifier, which in turn, is connected to the nitrogen pressure source.Pressure intensifier shall be constructed to boost the pressure from the nitrogen pressure source to preselected levels as determined by the full scale range of the instrument being calibrated.Shall also produce a pressure transducer excitation voltage and receive, process and display pressure transducer output signals
