Low pressure sensors measure +/- 0.1 H2O with conditioned analog outputs

SERVOFLO LPSI/LPS2 Series ultra low differential pressure sensors measuring from 0.1″ to 5″ of water in various non-directional or bi-directional calibration ranges. Based on a MEMS thermo-anemometer, product series infers differential pressure from a nano-liters per second gas flow through an integrated airflow channel. The on-chip circuitry provides analog amplification and temperature compensation to send an accurate linear output over a wide temperature range (±2.5% FS from 5C – 55C). Product comes in various ranges from 0.1″ to 2″ of water while the LPS2 is available from ranges between 1-5″ of water. Standard input voltage is 5Vdc and a 3V model is also available.
