Specifications
There are several key specifications that are used throughout our literature.
The mathematical definitions are listed below.
•
Offset –
the normalized output of a sensor (in V/V) with no applied stimulus.
•
OffsetTC1
– The linear drift of the sensors’ offset given in % of span/
o
C.
•
NonlinOffsetDrift
– The second order (quadratic) drift of the offset. This
coefficient is in
% of span
at room temperature.
•
OffsetTC2
– The second order (quadratic) drift of the offset. This
coefficient is in
% of span/
o
C
2
at room temperature.
•
Span –
the amount of change in normalized output voltage (in V/V) of the
sensor over the entire range of applied stimulus.
•
SpanTC1
– The linear drift of the sensors’ span given in % of span/
o
C.
•
NonlinSpanDrift
– The second order (quadratic) drift of the offset. This
coefficient is in
% of span
at room temperature.
•
SpanTC2
– The second order (quadratic) drift of the span. This coefficient
is in
% of span/
o
C
2
at room temperature.
•
PressureNonlinearity
– The second order (quadratic) nonlinearity versus
applied signal given in % of span.
