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
