Ultra-Low-Pressure Sensors

Servoflo ultra-low-pressure sensorThe LPSI/LPS2 Series includes ultra-low differential pressure sensors that measure from 0.1 to 5 inches of water in various non-directional or bi-directional calibration ranges. Based on a MEMS thermo-anemometer, the LPSI/LPS2 Series infers differential pressure from a nanoliters-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 5° to 55°C). The LSP1 comes in various ranges from 0.1 to 2 inches of water while the LPS2 is available in ranges between 1 and 5 inches of water. Standard input voltage is 5 V dc, and a 3-V model is also available. Key features include immunity to dust contamination and humidity.
