  • Reference instrument for defining the pressure scale in the range up to 100 bar pneumatic or to 400 bar pneumatic with an gas to oil separator
  • 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:
  • Total measurement uncertainty to 0.008% of reading
  • 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
  • Quick and safe replacement of the piston-cylinder system for measuring range changes via patented ConTect quick-release system as an option

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 enable 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 CPB5000 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 CPB5000 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 masses. As standard, these masses are manufactured to the standard gravity (9.80665 m/s²), 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 metering valve. For further pressure increases and fine adjustment, a very precisely controllable spindle pump is fitted, which only runs within the pump body.
