Now available from Sensortechnics GmbH , the new LBA series of differential pressure sensors offers differential low pressure measurement with ranges of 250 and 500 Pa Full Scale.

The LBA differential pressure sensors perform fully analog on-chip CMOS signal conditioning to allow for linear and temperature compensated outputs with high differential pressure resolution of typ. 0.1 % and fast response times of typ. 1 ms.

Featuring superior sensitivity and offset stability, these devices are based on thermal flow measurement of gas through a micro-flow channel integrated within the sensor chip. This very narrow channel decreases the flow through the LBA differential pressure sensor by several magnitudes compared to other flow-based pressure sensors.

The ultra low gas flow ensures high immunity to condensation and dust contamination and allows the use of connecting tubes and input filters without the need to recalibrate or correct the output signal. As the flow impedance is predefined at the sensor chip level, the LBA series provides very small and cost-effective PCB-mountable housings.

Sensortechnics’ highly sensitive LBA differential pressure sensors are ideal for detecting very small pressure differences in industrial HVAC applications, as well as many medical respiratory devices, such as:

  • ventilators
  • spirometers
  • sleep diagnostic equipment
  • nebulizers and oxygen concentrators/conservers.
