Description of the Mass Set
All masses of the Mass Set as supplied with this gauge are made of non-magnetic,
austenitic (series 300) stainless steel (1). They are machined from rolled stock or forgings,
and the removal of any metal is performed in such a way as to maintain balance about the
centerline. Final mass adjustment is usually accomplished by drilling a symmetrical
pattern of holes concentric with the axis.
Description of the Gauge Base
The Gauge base incorporates simple, sturdy construction and is equipped with three
adjustable feet.
1. Mass carrier composite construction 300 Series, Non-magnetic, Austenitic, Stainless
Steel and other non-magnetic material.
The base has an integral thermowell to accommodate a glass thermometer, or
precision temperature probe (Platinum Resistance Thermometer). The thermowell
allows for accurate temperature measurement of the test media and Piston/Cylinder.
The base features pre-drilled holes to facilitate installation of inductive Float Position
sensors (RUSKA Model 2456 Piston Gauge Monitor or equal).
The most exciting feature of the base is the “Split-Column” design. This design
allows for piston cylinders of different configuration to be mounted on the same base
and operated with the same mass set. The Split Column allows for the operation of
the base with the standard 2470 Piston/Cylinder as shown in Figure 3-1 and with the
2468 Low-Range or the 2468 Mid-Range Piston/Cylinders as shown in Figure 3-2.
