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 LDW-H 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 LDW-H 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
In the stable instrument base, the integrated priming pump and the 250 ml tank enable large test volumes to be easily filled and pressurised. For further pressure increases and find adjustment, a very precisely-controllable spindle pump is fitted, which only runs within the pump body.
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 item under test.
High-performance instrument range
The LR-Cal LDW-H instrument base is available in 2 variants:
As standard, both instruments bases are fitted with a connection for the piston-cylinder system with 3/4" BSP female thread.
With the 1,200 bar instrument base, a quick-release mechanism is available as an option. This enables the piston-cylinder system to be changed quickly and safely without any tools.
The connection of the test item is made without tools using a quick-connection. Via the freely-rotating knurled nut, the test item can be oriented as required. As standard, a threaded insert with a 1/2" BSP female thread is provided. Other threaded inserts are available to connect the most common pressure measuring instruments.
LR-Cal Druck & Temperature is a Germany manufacturer of pressure, temperature, and torque/force measurement and calibration equipment. Available products include temperature baths, dry block calibrators, pressure pumps, pressure calibration kits, digital/analogue pressure measurement gauges, and process calibrators.
