The DH-Budenberg CPB5000 pneumatic deadweight tester is a precision pressure calibration instrument ideal for testing a wide range of pressure measurement tools such as gauges and sensors. The CPB5000 provides a simple, economic solution for calibrating pressures of up to 400 bar (5000 psi) while maintaining a total measurement uncertainty of just 0.008 % of reading. A fully stand-alone instrument with integrated pressure generation and the pure mechanical measuring principle, the CPB5000 is ideal for on-site use for maintenance and service.
The DH-Budenberg CPB5000 deadweight tester consists of a pneumatic base to which a piston/cylinder system is attached. Replacing the piston/cylinder allows changing of the measurement range. One available option, the ConTect System, allows quick and easy changing of the piston/cylinder assembly without the need for tools. Simply twist the butterfly screw and the installed ConTect System can be removed and a new range installed.
The piston and cylinder of the CBP5000 are both manufactured from tungsten carbide. Compared to other materials, tungsten carbide has very small pressure and thermal expansion coefficients, which results in a very good linearity of the effective cross-sectional area of the piston and thus a high measurement accuracy. The piston and cylinder are very well protected against contact, impacts or contamination from outside in a solid stainless-steel housing.
To allow easy installation and removal of the device under test (DUT) without tools, the CPB5000 utilizes a quick connector that seals with hand-tightening. A variety of adapters are provided to handle most any thread type found on the DUT.
The DH-Budenberg CPB5000 instrument bases are available in the following three designs:
