LBA differential pressure sensors from Sensortechnics GmbH are based on thermal mass flow measurement of air or gas through a micro-flow channel integrated within the silicon sensor chip.
LBA pressure sensors achieve excellent resolution and offset stability due to the highly sensitive measuring principle.
Sensortechnics’ highly sensitive LBA differential pressure sensors are ideal for detecting very small pressure differences in many medical, HVAC, analytical and laboratory OEM device applications.
Now available in ultra-low pressure ranges from 25 Pa Full Scale in addition to the existing 250 Pa and 500 Pa ranges, the new LBA series differential pressure sensors perform fully analogue 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 LBA 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 while allowing the use of connecting tubes and input filters without the need to recalibrate or correct the output signal. Complex housing constructions are eliminated, making small and cost-effective PCB-mountable devices possible.
Key features of LBA series differential pressure sensors:
- New ultra-low pressure ranges from 25 Pa Full Scale
- Excellent resolution and offset stability
- High immunity to dust contamination and condensation
- Connecting tubes and input filters do not affect sensor performance
