  • Masses manufactured from stainless steel and aluminum
  • Local gravity adjustment possible at no additional charge
  • Compact dimensions

The DH-Budenberg CPB3800 deadweight tester features an accuracy of 0.025% and compact size making it ideally suited to on-site, field calibration as well as service and maintenance of pressure transmitters and mechanical gauges. With integrated (hydraulic) pressure generation and a purely mechanical measuring principle, there is no electrical power required for operation.

The pressure is set via an integrated, finely adjustable, precision spindle pump. As soon as the measuring system reaches equilibrium, there is a balance of forces between pressure and the force generated by the mass applied over the area of the piston. The quality of the piston / cylinder system ensures that this pressure remains stable over several minutes so that the device under test can be calibrated or adjusted.

In addition, the DH-Budenberg CPB3800 sets itself apart through its clearly arranged control elements. The built-in spindle pump is very easy to operate even at very high pressures, and features a threaded spindle which moves within the pump body. The spindle pump handle does not move in or out of the body of the pump as the handle is turned, therefore there are no cantilever forces or changes in the overall size of the base as the pressure is changed.

Deadweight testers are the most accurate instruments for the calibration of electronic or mechanical pressure instruments. The CPB3800 uses precisely machined, high-quality materials, resulting in high accuracy and an excellent long-term stability of five years.

Application Notes

Here's how some of our customers used this product.

Re-calibrating Pressure Gauges up to 15,000 psi

The Background: A customer in the Oil and Gas field has a large number of hydraulic, analog and digital gauges that need efficient and accurate calibration in the field.

The Problem: Though the sheer number of gauges and tough field conditions present a large challenge, the most pressing problem is the extremely high pressure ranges—up to 15,000 psi—of some of the gauges which is well beyond the capabilities of some pressure calibrators.

The Solution: Using the CBP3800 the customer can recalibrate all their gauges whether digital, analog or hydraulic; up to a full range of 16,000 PSI with an accuracy of 0.025% of reading. Another advantage of the CPB3800 is that the unit is fully self-contained and has a high long-term stability without the need to be recalibrated annually as it has no electronics that can drift.
