Brunson M-Series Portable Metrology Stands

Sometimes being a lightweight is a good thing

The M-Series metrology stands have been requested both by customers and other metrology instrument OEMs. With their input, Brunson has designed this instrument stand for functionality and portability. This collapsible, tripod-type stand is available in a number of standard configurations. Just tell us your preference.

Graphite or aluminum legs. These stands are available with aluminum or graphite double upper legs, which span from the shoulder pivots to the “knee” of the stand. Stands with graphite upper legs have a lower weight and give an advantage with respect to thermal stability.

Adjustable or fixed instrument mount. The stand is available with either an adjustable instrument column, also called the “intermediate tube” (below left) or with an instrument adapter fixed directly to the tribrach at the top of the stand (below right). The adjustable instrument mount employs a handwheel-driven worm gear for up-and-down adjustment of the instrument column. The collar may then be clamped to avoid any inadvertent instrument movement. An adapter on top of the intermediate tube provides a standard external 3½”-8 thread for mounting instruments or other adapters. Note that the intermediate tubes on our M-Series portable stands do not have the same internal threads as found on our bigger stands, and as such will not directly accommodate adapters such as the model 800 precision lift.

Also: 5/8th adapters are also common and can be found here.

The “fixed height” version of the stand has an adapter mounted directly to the top of the stand. For applications where fine vertical adjustment of the instrument is not necessary, this version reduces cost and increases lateral stability.

Note that the height of either type of stand (fixed or adjustable mount) may be adjusted by extending and locking the lower legs at the desired position.

Short or tall. The M-series stands are available in a short or tall version. The double upper leg section and the adjustable instrument column of the tall version are longer, providing the additional height. The lower leg sections are the same length on both versions.

Points or pads. The stand’s lower leg will accommodate two different types of feet – trivet points (image left top) or swivel pad feet (image left bottom). The swivel pads have a thin, textured rubber pad on the bottom. Either type of foot is an acceptable choice for general applications. The points work well on uneven surfaces, the pads work well on smooth surfaces (e.g., finished concrete) to resist sliding and soft surfaces (e.g., linoleum) which the points may damage. Pads have the additional advantage of being outfitted with a hole for semi-permanent mounting. The feet are easily interchangeable in the field. The M-Series comes standard with both trivet point feet and pad feet.
