Specifications
(1) Accuracy is the sum of worst case linearity, repeatability, hysteresis, thermal effects and
calibration errors over the operating temperature range. Full scale for differential ranges is the sum
of + and – ranges. Pressure range 1psi gauge has digital accuracy of ±0.15% FS maximum; analog
accuracy of ±0.18% FS maximum. Calibration is traceable to NIST. (2) Tighter accuracy available on
some models - consult factory. (3) Exposure to overpressure will not permanently affect calibration
or accuracy of unit. Burst pressure is the sum of the measured pressure plus the static pressure and
exceeding it may result in media escape. (4) User confi gurable. (5) Recommended load impedance
of 100 k-ohm or greater.
