Overview

The innovative LDE technology features superior sensitivity especially for ultra-low pressures. The extremely low gas flow through the sensor ensures high immunity to dust contamination, humidity and long tubing compared to other flow-based pressure
sensors.

Benefits

Ultra-low-pressure ranges from 25 to 500 Pa (0.1 to 2 inH2O)
Pressure sensor based on thermal microflow measurement
High flow impedance
Very low flow-through leakage
High immunity to dust and humidity
No loss in sensitivity using long tubing
Calibrated and temperature compensated
Unique offset autozeroing feature ensuring superb long-term stability
Offset accuracy better than 0.2% FS
Total accuracy better than 0.5% FS typical
On-chip temperature sensorAnalog output and digital SPI interface
No position sensitivity
