4.4.1 Static characteristics
Calibration curves indicates the static characteristic properties (see schematics)
These curves give the most important behavior of sensors: the relationship between the output
signal (S) and the measurand (M).
Sensitivity is defined as the slope of the former function. In linear ranges, it is a constant (see
below).
FSO stands for full-scale output of the sensor. This is the maximum (or nominal) output signal.
Linearity is the closeness of a sensor's calibration curve to a specified straight line. It is
expressed as a percent of FSO, which means the maximum deviation of any calibration point
from the corresponding point on the specified straight line The limit of detection is the lowest
value of measurand that can be detected by the sensor. Resolution is the smallest increment in
the output, given in percent FSO. The zero-measurand output ("the zero" or offset) is the
output when the zero measurand is applied. Zero shift (or drift) is a change in the zeromeasurand
output under specified conditions.
