Description

Applications:
  • Reference instrument for the calibration of differential pressure measuring instruments under static pressure
  • Primary standard for factory and calibration laboratories for the testing, adjustment and calibration of pressure measuring instruments
  • Complete, stand-alone system, also suitable for on-site use
Special Features:
  • Measuring range (= static pressure + differential pressure) up to 400 bar pneumatic, up to 1,600 bar hydraulic
  • Total measurement uncertainty to 0.008% of differential pressure plus 0.0001% (1 ppm) of static pressure
  • Factory calibration includes traceability to national standards, as standard; with DKD/DAkkS calibration possible as an option
  • High long-term stability with recommended recalibration cycle every five years
  • Masses manufactured from stainless steel and aluminum, can be adjusted to local gravity


Proven Primary Standard

Pressure balances are the most accurate instruments available on the market for the calibration of electronic or mechanical pressure measuring instruments. The direct measurement of the pressure (p= F/A), as well as the use of high-quality materials enables a very small measurement uncertainty, in conjunction with an excellent long-term stability of five years. The pressure balance has therefore been used for years in factory and calibration laboratories in industry, national institutes and research laboratories.

Stand-alone Operation

Due to its integrated pressure generation and the pure mechanical measuring principle, the model CPB5600DP is ideal for on-site use for maintenance and service.

Basic Principle

Pressure is defined as the quotient of force and area. The core component of the CPB5600DP is therefore a very precisely-manufactured piston-cylinder system, which is loaded with masses in order to generate the individual test points. The masses applied are proportional to the target pressure and this is achieved through optimally graduated weights. As standard, these masses are manufactured to the standard gravity (9.80665 m/s¯), though they can be adjusted to a specific location and also DKD/DAkkS calibrated.

Easy Operation

The pressure setting depends on the instrument design and is either done via an integrated pump or from external pressure supply via a meeting valve. For fine adjustment, a very precisely-controllable spindle pump is fitted, with a precision spindle running within it. As soon as the measuring system reaches equilibrium, there is a balance of forces between the pressure and the mass load applied. The excellent quality of the system ensures that this pressure remains stable over several minutes, so that the pressure value for comparative measurements can be read without any problems, or also so that more complex adjustments can be carried out on the test item.
