4. Specifications
Accuracy specifications presented herein are obtained by comparison with primary standards trace-
able to the National Institute of Standards and Technology (NIST). These specifications are obtained in
accordance with the ISO Guide to the Expression of Uncertainty in Measurement (GUM). Any excep-
tion are noted on the individual calibration certificate.
Mensor reserves the right to change these specifications without notice.
4.1 Measure Specifications
Uncertainty 0.01%Intelliscale-50 (0.01%IS-50) provides 0.01% of
reading uncertainty from 50% to 100% of the full scale
value of the sensor and an uncertainty of 0.005% of
full scale from 0% to 50% of the full scale value of the
sensor. The 0.01%IS-50 specification has a 365 day
calibration interval. Uncertainties for these ranges are
denoted below as “0.01%IS-50 (365 days)” or Type
“IS”.
Ranges with uncertanties denoted below as “0.01%FS
(180 days)” or “0.01%FS (365 days) can have two
turndown ranges on the transducer. Each range has
0.01%FS uncertainty. The second turndown range
span cannot be less than 50% of the primary turn-
down range span. The 0.01%FS specification has a
180 or 365 day calibration interval depending on the
range.
Uncertainties include all pressure effects, temperature
effects and calibration stability over 180 days after re-
zeroing.
