 Product Description

Brunson 545-160 Tilting Level Kit

The Level that thinks it's an Alignment Telescope

The 545-160 (or the metric version, 545-160M) comes standard with a dual axis micrometer, combining many of the capabilities of our alignment telescopes with our precision sight level. The dual axis micrometer allows you to measure deviations from the line of sight in both the horizontal and vertical directions simultaneously. These models provide a means of easily combining two types of measurements – level and straightness – in one instrument. This is beneficial for applications such as bore alignments for drive systems, turbine alignments, gearboxes, extruders, engine bearing lands and laboratory optical paths. The 545-160/545-160M is an effective configuration when large mechanical components must be set level as well as straight.

All 545 models give you the ability to establish a line of sight which is extremely level. The two-speed telescope tilting screw has a coarse thread to get you in the ballpark quickly, and a fine thread for those precise adjustments which bring you into perfect level. In addition, a coincidence-type level with 2.5 times magnification optically “folds” both ends of the precision level vial’s bubble together, enabling you to detect the tiniest deviation from level. One arcsecond of tilt is discernible using this “coincidence” vial methodology.

This instrument includes a telescope having adjustments to maintain the line of sight straight throughout a focusing range of two inches to infinity, allowing the instrument to be located in the tightest of setups. This straightness is maintained at ±0.001″ (0.025mm) from two inches to 17 feet (50.8mm to 5.2m) and one arcsecond from 17 feet to infinity. The main telescope tube has a removable section to facilitate conversion for autocollimation, autoprojection, or installation of a right angle eyepiece. The optical micrometer produces repeatable readings with a resolution of 0.001″ (0.025mm).

The reticle’s filar/bifilar pattern makes for easy use with our optical tooling scales, or during collimation and autocollimation procedures. The horizontal axis pivots directly over the vertical axis, making the change in plane height less than 0.0001″ for tilts up to 5 arc minutes either above or below horizontal. This important feature eliminates the need to perform the time-consuming precision plumbing procedure for leveling projects. All 545 models use high quality base components and leveling vials similar in design to our model 76-RH transit, allowing this instrument to sweep precise planes. For rough leveling, the unit has a circular level vial mounted on the base.

Brunson's extreme attention to engineering details means that you can take measurements with accuracies that are difficult to achieve by conventional mechanical methods.
