Term “operating temperature” refers to ambient temperature at which sensor operates and its
intrinsic safety is ensured, but sensor accuracy stated in Table 3 is provided only in specified temperature
range
(see Table 5 and Table 6).
3
To provide metrological properties during sensor lifetime, span calibration should be performed
periodically (see

).

For variability in whole operating temperature range for any sensor modification refer to Table 6.
