Pressure Sensors Go Ultra Low

The LPSI/LPS2 Series ultra low differential pressure sensors measure from 0.1” to 5” of water in various non-directional or bi-directional calibration ranges. Based on a MEMS thermo-anemometer, the components infer 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 a linear output over a temperature range from 5°C to 55°C (±2.5% FS). The LSP1 comes in various ranges from 0.1” to 2” of water while the LPS2 is available between 1” to 5” of water. Standard input voltage is 5 Vdc and a 3V model is also available. Depending on the model, prices range from $22 to $28 each/1,000. SERVOFLO CORP., Lexington, MA. (781) 862-9572.
