3. Product Description
3.1 General Description
The Mensor CPC 6000 Automated Pressure Calibrator is a multi-channel/multi-range pressure system
designed to test and calibrate a variety of pressure devices in either absolute or gauge pressure
modes. The CPC 6000 can have two independent control channels each with its own pressure
regulator. Each control channel can have up to two transducers. Transducers can be of two types:
“Intelliscale Transducers” (IS) or “Turndown Transducers” (TD).
Intelliscale Transducers (IS) have an accuracy of 0.01%Intelliscale-50 (0.01%IS-50). This specification
is a percent of reading specification with a 365 day calibration stability and is explained in
Section 4 of
this manual. The 0.01%IS-50 specification is available in all new CPC 6000’s and applies to full scale
ranges above 15 psi absolute or gauge. CPC 6000s with software version 1.25 and below require a
software upgrade to version 1.26 or greater to be able to communicate with Intelliscale Transducers.
Turndown Transducers (TD) can have two ranges configured on each transducer. These ranges are
referred to as turndowns and each one has an uncertainty of 0.01%FS with a calibration stability of
185 days. The second (lower span) turndown cannot have a span that is less than 50% of the primary
turndown span. Turndown Transducers can be used in all CPC 6000 sofware versions.
Below is a software version comparison matrix.
