4. Specifcations

Accuracy specifcations presented herein are obtained by comparison with primary standards traceable to

the National Institute of Standards and Technology NIST). A calibration data report has been provided with

your new CPC8000 instrument, traceable to NIST. The calibration program at Mensor is accredited to both

ISO/IEC 17025:2005 and Z540-1-1994 by A2LA. Mensor, LP is registered to ISO 9001:2008.

Mensor reserves the right to change these specifcations without notice.

See Table 4.6.1 for available Transducer Type, Range, Mode & Uncertainty)

Maximum ratio between highest and lowest range is 10:1

Measurement units

psi, inHg@0C, cmHg@0C, mmHg@0C, inH2O@4C, 20C, bar, mbar, cmH2O@4C and 20C, hPa, kPa,

Pa, MPa, kg/cm sq, and 2 user-defned units. All above in rate (per second, per minute and per hour).

Resolution

Operator selectable from 4 to 6 digits

Calibration adjustments

Zero adder and Span multiplier or up to 11 point linearization for each sensor

Calibration interval

365 days for IS-33 or IS-50 and 180 days for standard transducers, with periodic re-zeroing.

Calibration data storage

The calibration data is stored on the sensor.

Measurement flters

Of, low, normal (default), high

Defnitions: Max = the maximum value of a range, also known as the full scale value. Example, for a range of –15 ... 145, Max = 145

Min = the minimum value of a range. Example, for a range of –15 ... 145, Min = –15

Full Span = Max – Min. Example, for 0 ... 145 the Full Span is 145, for –15 ... 145 the Full Span is 160

Reading = The value of the sensor output

(1) Total Uncertainty (k=2) includes hysteresis, linearity, repeatability, reference standard, drift and temperature efects over the calibrated range for the calibration interval speci-

fed, with periodic re-zeroing.

(2) 0.01% Intelliscale-50 (0.01% IS-50): Uncertainty from Min to 50% of Max = (0.010% x 50% x Max) or 0.010% of reading from 50% to 100% of Max for 365 days.

(3) 0.01% Full Span (0.01% FS) = Uncertainty of 0.01% of the Full Span for 365 days.

(4) 0.008% Intelliscale-33 (0.008% IS-33): Uncertainty from 0 to 33% of Max= (0.008% x 33% x Max) and 0.008% of Reading from 33% to 100% of Max for 365 days.

(5) 0.008% Intelliscale-50 (0.008% IS-50): Uncertainty from 0 to 50% of Max = (0.008% x 50% x Max) and 0.008% of Reading from 50% to 100% of Max for 365 days

4.2 Control Specifcations

External pressure

requirements

Source Requirements – 10% over range of highest pressure transducer

Exhaust Requirements – Vacuum source required for any control below atmosphere

Control stability

0.002% FS of highest range sensor at the set point

Pressure range ratio

Maximum ratio between highest and lowest range is 10:1

Minimum control pressure

0.05% FS of highest range sensor or .025 psi over exhaust pressure, whichever is greater
