SP160

SP160 is a SP series differential low pressure sensor with spirometry applications. It employs NimbleSense™ a proprietary architecture achieving very high dynamic range to create the industry’s highest performing Spirometry pressure sensing device. This wider dynamic range is ideally suited to offer precise near zero measurements to support the demanding functional requirements of the Spirometry market. Selectable multiple pressure ranges are now supported in a single package. The SP Series family provides a new level of sensor integration into the Spirometry market combining an advanced piezoresistive sensing element with integrated amplification, ADC, DSP and processor intelligence to greatly simplify customer integration efforts. Industry leading accuracy performance. The SP series measures dry air and non‐aggressive gas pressure with very high accuracy better than 0.10% FS and Total Error Band is also industry leading which is typically better than 0.15% FSS.
