Terminology References
Digital Pressure Sensor Model PSD
BSL: Best Straight Line
The reference line according to the BSL or the minimum value adjustment is placed in such a way that the maximum positive and negative deviations are as small as possible.
Specifications: Accuracy NLH (BSL)
Long-term Stability and Long-term Drift
The change of accuracy due to aging under certain reference conditions during a period of time, typically one year.
Non-linearity
The largest deviation from the effective characteristic line of an ideal reference line. The reference line can be defined as a limit point adjustment, a BSL, or a BSL through 0.
Specifications: Non-linearity, Hysteresis
BSL/0: Best Straight Line through Zero
As an additional requirement for the minimum value adjustment, the BSL through zero (also BSL/0) must go straight through zero or the origin.
Specifications: Accuracy NLH (BSL through Zero)
NLH: Non-linearity and Hysteresis
Largest deviation from the ideal characteristic line (BSL, BSL/0 or limit point). In pressure measuring instruments, the non-linearity and pressure hysteresis are given together at a constant temperature.
TEB: Total Error Band
Total error (root from sum of the square of the deviations) due to measurement deviations (accuracy) and temperature influence (temperature coefficient TC). The temperature influence is usually given in the information across a range larger than that given in the standard (-10...60 °C).
TC: Temperature Coefficient
Change of measured value for zero point and span as a result of changes in temperature.
