The LME differential low pressure sensors are based on thermal flow measurement of gas through a micro-flow channel integrated within the sensor chip. 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. The low profile sensors of the LME series feature a total height of only 9 mm including pressure ports and allow for flexible direct manifold assemblies. Further, the SMT devices are highly versatile to fit to custom adaptors for application-specific mounting requirements.
Due to their excellent sensitivity, accuracy, offset long term stability and long service life, LME sensors are ideal for differential pressure gas flow measurement in bypass configuration. They offer measuring ranges from 25 Pa (0.1 inH2O) Full Scale.
