Features
- Pneumatic provision of pressure on site, in the laboratory or in the workshop up to 120 bar
- For the testing, adjustment and calibration of all types of pressure measuring instruments
- Two fine metering valves for pressure inlet and pressure outlet or vacuum
- Precisely adjustable volume adjuster for fine adjustment of pressure
- Connection for external pressure or vacuum source
- Pressure gauge for indicating the approximate pressure
- Compact dimensions make the CPP120-X particularly suited for on-site applications
The DH-Budenberg CPP120-X Comparison Pump is designed to provide pneumatic pressure for the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements. These units can be used in the laboratory or workshop, or on site at the measuring point. The DH-Budenberg CPP120-X Comparison Pump is capable of reaching pressures to 120 bar. By connecting the test item and a sufficiently accurate reference pressure measuring instrument to the test pump, the same pressure will act on both measuring instruments. By comparison of the two measured values at any given pressure value, a check of the accuracy and/or adjustment of the pressure measuring instrument under test can be carried out. For the precise setting for accurate comparative testing, the pump features a precise volume adjuster. The connection for the necessary external pressure or vacuum source is located on the rear panel. The individual test points can be easily controlled with the two integrated fine metering valves for pressure inlet and pressure outlet. The two test connections are equipped with G ½ female loose union connections. Corresponding thread adapters are available for the calibration of instruments with different connection threads. The CPP120-X is also particularly notable for its compact dimensions, which are not altered during operation, since the spindle runs within the pump body. With those dimensions, the exceptionally robust ABS plastic case and the low weight associated with these, the CPP120-X is also particularly suited for on-site applications.
