Deadweight Tester
for Differential Pressure Calibration
CPB5000-DP
Differential Pressure Deadweight Tester ( Pressure Balance)
CPB5000-DP
Real differential pressure calibration
• Pneumatic ranges: up to 100 bar / 1500 psi
Hydraulic ranges: up to 1000 bar / 15000 psi
• Accuracy (total uncertainty): up to ±0.008% of measured value
• Tester with two piston-/cylinder-units and two weight sets
• One spindle pump for generating the static line pressure,
another one for generating the differential pressure
• Options: DKD certification, IKM intelligent calibration module for automatic calculation of corrections etc.
Deadweight Tester (Pressure Balances) are the most accurate instruments for the calibration of electronic or
mechanical pressure measuring instruments.
The differential pressure deadweight tester CPB5000-DP allows a real calibration of differential pressures, based on
static line pressure.
The CPB5000-DP includes two common pressure balances of the basic series CPB5000. For the calibration of
differential gauges at a static line pressure, the systems can be separated.
One system is used to generate the line pressure. The second one supplies the differential pressure (including line
pressure).
For the basic specification, see datasheet CPB5000.
A certificate of calibration, traceable to national standard is included in standard scope of supply. As an option, a DKD
certification is available.
The differential pressure deadweight tester CPB5000-DP are available in two accuracies:
• ±0.015% of measured value, or
• ±0.008% of measured value
Optional Accessories:
• Intelligent Calibration Module IKM (see datasheet "IKM'). This module measures ambient values like temperature,
humidity, barometric pressure, as well as the temperature of the piston/cylinder system and makes an automatic
calculation of the corrections.
• Set of trim-masses for generating intermediate values (weights 1 mg to 50 g)
• Oxytester (purifier) for measuring instruments where the filling medium should not come into contact with the
deadweight tester.
• Dirt trap for test objects that are very dirty in order to avoid the penetration of dirt particles into the deadweight
tester
• Set of adapters in a tool case with 5 most commonly used threaded adapters, and a spanner
Standard Scope of Supply:
• Basement
• 1 priming pump and 2 spindle pumps (pressure generation and adjustment), with bypass-valve
• 2 connections for test specimen • *\ Liter operating fluid (at hydraulic types)
