Sensor technology offers unmatched sensitivity for differential low pressure measurement


S


ensortechnics’ new LBA series offers differential low pressure measurement with ranges of 250 and 500Pa Full Scale. The LBA sensors perform fully analog on-chip CMOS signal conditioning to allow for linear and temperature compensated outputs with high differential pressure resolution of typically 0.1 per cent and fast response times of typ. 1ms. The LBA sensors feature superior sensitivity and offset stability. The 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 sensor by several magnitudes compared to other flow-based pressure sensors. The extremely low gas 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. Because the flow impedance is


predefined at the sensor chip level the LBA series provides very small and cost-effective PCB-mountable housings. The LBA differential pressure sensors detect very small pressure differences in many medical respiratory devices such as, eg, ventilators, sleep diagnostic equipment


and oxygen concentrators as well as industrial HVAC applications. l
