13. D6 NTC temperature sensor ZAD040FS / FS2
D6 NTC sensor connector ZAD040-FS/FS2 incorporates a dedicated 24-bit A/D con-
verter; it can record the temperature of one or two high-precision NTC sensors (accu-
rate to 0.1 K and with a resolution of 0.01 K or even 0.001 K). Linearization accuracy
can be ignored because calculation is on a formula basis. Since the sensor does not
depend on an evaluating unit for its overall accuracy, it can also undergo multi-point
adjustment and independent calibration.
