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
