The model BL510 portable deadweight tester provide a precise means for generating pressure with high accuracy that
can be used as a primary calibration standard. The unit's built-in shuttle valve provides the means to control the rate of
pressure increase, while precision adjustment is accomplished with an integral micro vernier displacement valve. An ideal
product that offers a rugged field ready primary standard, certified to yield consistent accurate results.
1.2 Application
Primary Pressure Standard in lab or site
Secondary Reference Pressure Standard in lab or site
1.3 Operating Principle
A deadweight tester is based on a high accurate manufactured piston and cylinder assembly. This cylinder is mounted in
a column. The piston can rotate and freely move up and down. Accurately calibrated masses are loaded on top of the
vertically mounted piston. A pressure is applied on the bottom of the piston to lift the piston with masses. This creates a
balance between the downward force made by the masses and the upward force made by the pressure. With the known
effective area of the piston the pressure can be calculated.
