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.
