Precision laser alignment made easy
The rugged Fluke 831 has an intuitive guided user interface that enables quick and complete shaft alignment without advanced training or complicated programs. And while it’s easy to use, laser alignment with the Fluke 831 is powerful enough for the skilled technician. You can cover more of your machines with all the functionality needed on the plant floor, from thermal growth to user defined tolerances and more.

Reduce costs by avoiding downtime
Misalignment causes at least half of all damage to rotating machinery, studies show. Instead of fixing the problem, teams often just treat the symptoms of misalignment and replace bearings, couplings, and seals because they think alignment takes too long.
Contrary to expectations, laser alignment can be fast and easy. So, every machine that is repaired and overhauled should be aligned – not just a few. Teams that embrace laser alignment can save thousands of dollars per year by avoiding downtime and energy waste and reducing the number of bearings and seals they have to replace.

Operating principle
Deadweight testers are the high performance pressure standard for pressure measurement. Utilizing the well proven piston-gauge system consisting of a vertically mounted, precision lapped piston and cylinder assembly, accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder. These weights balance the upward force created by the pressure within the system. The pressure is measured when placed on a correctly spinning and floating piston. The total pressure measured is the summation of the weights plus the piston weight carrier assembly.
Instrument base
There are three basic variations in the hydraulic offering; single low pressure, single high pressure and dual piston models. Pressure is generated and controlled by means of a high quality screw press located on the front of the tester. A built-in hand pump is included as standard for all hydraulic models to prime the system and accommodate large volume requirements.

Piston/cylinder assemblies

The piston/cylinder assembly is the heart of each deadweight tester. They are manufactured from materials that provide stability, durability, and low thermal coefficients and distortion. Our experience and knowledge of piston/cylinder production and calibration ensure the precision and performance required for today’s demanding calibration requirements.

Weight masses

Standard weight masses are series 3 nonmagnetic austenitic stainless steel. Each mass is marked with the serial number of the instrument and the nominal pressure value relative to the high or low-pressure piston, when applicable. Optional fractional weights are stainless steel and/or solution heat treated aluminum.
Gravity correction

Gravity varies significantly with geographical location and this variation has a direct effect on the force of the weights and the accuracy of the deadweight tester. Each instrument can be calibrated to local gravity at no extra cost. If unspecified, instruments will be calibrated to Standard Gravity at 980.665 cm/s2.
