The First Sensor LDE differential pressure sensors are based on thermal mass flow measurement of air or gas through a micro-flow channel integrated within the silicon sensor chip. Due to the highly sensitive measuring principle the LDE sensor achieves excellent resolution and offset stability. The LBA series now offers, ultra-low pressure ranges from 25 Pa (0.1 inH2O) Full Scale in addition to the existing 250 Pa and 500 Pa ranges (1 and 2 inH2O). The LDE sensors perform fully analog on-chip CMOS signal conditioning to allow for linear and temperature compensated outputs with fast response times.

By integrating the micro-flow channel on the sensor chip level, the gas flow through the LDE sensors is decreased by several magnitudes compared to conventional flow-based pressure sensors. This extremely low flow ensures high immunity to dust contamination and condensation and allows the use of connecting tubes and input filters without the need to recalibrate or correct the output signal.

The First Sensor highly sensitive LDE differential pressure sensors are ideal to detect very small pressure differences from 25 Pa (0.1 inH2O) Full Scale in many medical, HVAC, analytical and laboratory OEM device applications.
