Proven primary standard
Pressure balances / deadweight tester are the most accurate devices 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 allow a very small measurement uncertainty in combination with an excellent long-term stability of 5 years (recommendation according to the German Calibration Service (DAkkS)). Pressure balances / deadweight tester have been used for years in factory and calibration laboratories of industry, national institutes and research institutes.
Autarkic operation
Due to the integrated pressure generation (for measuring ranges up to 10 bar) as well as the purely mechanical measuring principle, the LR-Cal LDW-P pressure balance is also ideally suited for on-site use, maintenance and service.
Grundprinzip
The mass support is proportional to the targeted pressure and is achieved by optimally graduated disc weights. These disc weights are manufactured as standard to the standard acceleration of gravity of 9.80665 m/s², but can also be optionally adapted to their specific location of use and also DAkkS calibrated.
Simple operation
In the stable basic unit, even large test volumes can be easily filled and compressed in the version up to 7 bar with the integrated priming pump. For further pressure build-up, a very precisely adjustable spindle pump with internally rotating spindle is installed. Ranges from 25 bar (up to 120 bar) have a connection for an external pressure supply (e.g. nitrogen bottle with pressure reducer).
As soon as the measuring system is in a floating state, there is a balance of forces between the pressure and the mass supports. Due to the excellent workmanship of the system, this pressure remains stable for several minutes, so that the pressure values for comparative measurement or even more extensive adjustment work can be carried out on the test specimen without any problems.
Two basic device versions
The LR-Cal LDW-P deadweight tester is supplied in one of the following two variants depending on the measuring range:
NOTE: When used with vacuum piston cylinder system, this second version with connection for external pressure/vacuum supply MUST be used.
As standard, the basic units are equipped with a connection for the piston-cylinder system with thread 3/4″ BSP male. A quick-action clamping fixture for the piston-cylinder system is available as an option (mandatory for vacuum range). This allows the piston-cylinder system to be changed quickly and safely without tools.
The test specimen is connected to a quick-connect system without tools. Due to the free-running knurled nut, the test specimens can be aligned as desired. A threaded insert with a 1/2″ BSP thread is included as standard. Further threaded inserts are optionally available, with which all common pressure measuring devices can be connected.
