Sensortechnics’ LBA series offers differential low pressure measurement with ranges of 250 and 500 Pa 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 % and fast response times of typ. 1 ms. 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. The extremely low gas flow ensures high immunity to dust contamination and condensation and allows the use of connecting tubes and input filters.
