We need to measure vacuum difference from zero to minus 150mbar below atmospheric pressure. The sensor will be connected to a PC oscilloscope and we will need a 0-10Vdc output signal with a high resolution to be able to measue very small changes in vacuum pressure. Which product should we consider?
We would suggest the DMP331i which has a 10 volt output pressure transducer with a 14 bit, 16384 steps, 0.0060% span high resolution output. The transducer is vented to atmosphere through the electronics housing and out of the electrical interface and the vacuum differential is measured by connecting the threaded port to the vacuum pressure.
