The pressure test pump LR-Cal LPP 1000 is used to generate pressure for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements. These pressure tests may be carried out in laboratories, workshop or on site at the measuring point.
If the instrument to be tested and a sufficiently accurate reference measuring instrument are connected up to the test pump, the same pressure is applied to the two measuring instruments when the pressure test pump LR-Cal LPP 1000 is operated. By comparing the two measure valuses at random pressure values, the accuracy can be verified or the instrument under test can be adjusted.
Despite its compact dimensions, the pressure test pump LR-Cal LPP 1000 is easy to operate and allows for exact generation of the required test pressures The LR-Cal LPP 1000 is fitted with a fine adjustment valve for a precise adjustment of pressures.
The reference instrument is screwd directly on the top of the pump and the unit under test is connected by means of the connection tube incorporating an adapter 1/4" BSP female thread (freely rotating), contained in the scope of delivery.

Proven primary pressure standard Deadweight Tester / Pressure Balances are the most accurate instrument 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 5 years (recommended in accordance with German Calibration Service DKD/DAkkS). The deadweight tester / pressure balance has therefore been used for years in factory and calibration laboratories in national institutes, research laboratories and in industry.
Stand-alone operation Due to its integrated pressure generation and the pure mechanical measuring principle, the model LR-Cal CPB5600-DP 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 model LR-Cal CPB5600-DP is therefore a very pecisely manufatured 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/s²), though the can be manufactured to a specific location (gravity) and also 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 fine adjustment, a very precisely controllable spindle pump is fitted, with a precisions 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.
The LR-Cal CPB5600-DP instrument bases are available in the following four designs:
The instruments include the components of two pressure balances in one housing. For the calibration of differential pressure gauges under a static pressure, the two systems are separated by a by-pass valve.
One of the systems is used to generate the static pressure, with the second system generating the differential pressure (incl. static pressure). It is recommended that one of the sets of trim-masses is used for this (see accessories).
The instrument bases, pneumatic to 100 bar and hydraulic to 1,000 bar are fitted with quick-release meachnism. This enables a quick and safe replacement of the piston-cylinder systems without any tools. The pneumatic instrument design with separator is fitted with a connection for the piston-cylinder systems with M30 x 2 female thread and the hydraulic high-pressure base version is fitted with a M30x2 female thread with sealing cone.
