Sensortechnics’ new LBA series offers differential low-pressure measurement with ranges of 250 and 500 Pa (1 and 2 in. H2O) full scale. The LBA sensors perform 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 low gas flow ensures high immunity to dust contamination and condensation, according to the company, 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 small and cost-effective PCB-mountable housings.
In related news, Sensortechnics’ new SSI stainless steel OEM pressure sensors can measure gage or absolute pressures in ranges from 3 to 500 psi. These devices achieve a Total Error Band (TEB) better than ±1.5% FSS over a temperature range of -20 to +85 °C (-4 to 185 °F), according to the company.
Sensortechnics’ SSI pressure sensors use digital signal conditioning and provide both analog 0.5-4.5 V output as well as digital I²C or alternatively SPI interfaces at the same time.
Available packaging options include diaphragm versions with weld ring or housings with G 1/8 threaded pressure ports. Sensortechnics’ customization service can provide mechanical or electronic modifications of its SSI pressure sensor series.
