differential low pressure sensorSensortechnics’ LBA Series offers differential low pressure measurement with ranges of 250 and 500 Pa (1 and 2 inch H2O) 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 typ. 0.1 percent and response times of typ. 1 ms. The LBA sensors feature desirable sensitivity and offset stability and are based on thermal flow measurement of gas through a micro-flow channel integrated within the sensor chip. This narrow channel decreases the flow through the LBA sensor by several magnitudes compared to other flow-based pressure sensors. The 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.
