I am new to the instrumentation Field.
We currently have two ways to calibrate our pressure devices.
We use a handheld pump from Fluke with digital readout which works fine for field measurements.
We also have a shop compressor (dry type) for our bench. However, the compressor is very erratic when building pressure and we cannot use this option for calibrations because of this. So we build up pressure in the system and then shut the valve. We then drop the pressure to the required points doing the calibrations as they fall.
Is there a good way to setup the compressor to be able to get stable incoming air pressure. Maybe regulators and such.
Any help would be greatly appreciated. Also I am considering using bottled gas but I am unsure what type would be used.
