Hydraulic Deadweight Tester differential pressure CPB5000-DP

Differential Pressure Deadweight Tester (Pressure Balance) for a real calibration of differential pressure under static pressure.
Accuracy (uncertainty) up to ±0.008% or ±0.015% of measured value (plus 0.0001% of the static pressure)

Applications:

    Reference instrument for the calibration of differential pressure measuring instruments under static pressure
    Primary pressure standard for calibration laboratories and factory, for the testing, adjustment and calibration of differential pressure instruments
    Complete stand-alone system, also suitable for on-site use

Features:

    Measuring range (= static pressure + differential pressure) up to 400 bar pneumatic and up to 1,000 bar hydraulic
    Total measurement uncertainty to 0.008% of differential pressure plus 1 ppm of static pressure
    Including factory calibration certificate; DAkkS certificate as option
    High long-term stability with recommended recalibration cycle every 5 years
    Masses made from stainless steel and aluminium, can be manufactured to local gravity
