Overview

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

Benefits

  • Ultra-low pressure ranges from 25 to 2500 Pa (0.1 to 10 inH2O)
  • Pressure sensor based on thermal micro-flow measurement
  • High flow impedance
  • Very low flow-through leakage
  • High immunity to dust 
  • Ho loss in sensitivity using long tubing
  • Outstanding long-term stability and precision with patented real-time offset compensation and linearization techniques
  • Offset long term stability better than 0.1 Pa/year
  • Total accuracy better than 0.5% FS typical
  • On-chip temperature sensor
  • Linearized digital SPI and analog outputs
  • Small footprint, low profile, only 9 mm in height, and robust package
  • Pressure ports for direct manifold assemblies
  • Highly versatile to fit to application-specific mounting adapters and manifolds
  • Minimized internal volume and manifold mount option allow for fast gas purge time
  • No position sensitivity
