PR4 | BODAS Pressure sensor Product description PR4 xxx xx 05 / 10 Tolerances of the PR4 xxx xx 05 / 10 sensor The tolerance of the pressure measurement is specified in % FS. FS = “full scale” refers to the nominal sensor pressure pn usable range (4 V). The relative tolerance is pressure- and temperature-dependent and increases over the service life. In this connection, the service life comprises the entire specified service life respectively all specified tests. Statistically, the tolerances for new parts are observed with ±3 s per production lot. 100% sorted products may be delivered....
