High Precision Pressure Sensor | Laboratory | DMP333i DMP331i

Highly precise with digital signal processing


The DMP333i and DMP331i high precision pressure sensor boast high accuracy measurements of 0.1% full-scale thanks to its 16-bit digital analogue converter signal processing.  Its output signal is pressure and temperature compensated before it is amplified to the desired output signal range.

Furthermore, its integral digital amplifier means the analogue output can be re-scaled with a turndown ratio of 1:10, while still maintaining its high precision.

Thanks to the high accuracy of the DMP333i and DMP331i high precision pressure sensor, it is ideal to use in laboratory applications and energy production (gas consumption and thermal energy measurement) requiring the highest level of accuracy.

IS-versions and Ex ia intrinsically safe for gases and dust versions are available on request for more hazardous environments.  Please contact our technical sales team.
