Description
A unique concept
The CPD8000 measuring principle lies on the principle of
the pressure balances and is based on the fundamental
equation which defines pressure: P = F/A with P as a
pressure, F a force and A an effective area.
CPD8000 is a worldwide exclusivity combining two high
level technologies:
•
Best available piston cylinder assemblies
; whose
effective area A is perfectly known
•
High accuracy force cell
which measure the force F.
CPD8000 is defined as a digital pressure balance and is a
high accuracy pressure measurer.
Primary principle
As a result, the CPD8000 measuring principle is a
primary principle; it associates the measurement
accuracy and reliability of fundamental pressure
standards with the ease of use of automatic digital
instruments.
Easy of use
Model CPD8000 offers same high accuracy as a high
end pressure primary standard with the benefits of:
•
No weights manipulation
•
Built-in reference mass for auto-calibration
•
Displaying of full corrected pressure
