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.
Please consider these optional accessories.
This product can be used in the following applications:
The Background: Our customer is an industrial food processor that has a large number of analog gauges and digital pressure sensors that need to be calibrated.
The Problem: As the gauges and sensors are used with food production, they are not able to use calibrators that rely on hydraulic fluid.
The Solution: We recommended the DH-Budenberg CPP120-X Comparison Pump paired with a Wika CPG1500 Reference Gauge. The CPP120-X provides pneumatic pressure using clean nitrogen supplied via bottle for testing, adjusting and calibrating of mechanical and electronic pressure measuring instruments through comparative measurements.
