Precision Screw-In Pressure Sensor | High Accuracy | LMP331i

Precise pressure or level measurement with digital signal processing


The LMP331i high precision screw-in pressure sensor boasts 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 LMP331i high precision screw-in pressure sensor, it is ideal to use in laboratory applications, chemical & petrochemical industries and environmental engineering applications such as water, sewage and recycling, all 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 team.
