360 Degree Survey Mini Prism Reflector L Bracket Monitoring Rail Total Station Prism

Model: L360

Usage:

The L-Bar Mini Prism is a compact and versatile optical target used with automated total stations (AMTS) to monitor displacements and deformations of structures.

Suitable for a wide range of applications, the L-Bar mini prism can be installed on tunnel walls, building facades, foundation slabs, retaining walls, and bridges decks.

How to Install:

Choose a location that provides a clear line of sight to the AMTS.

Determine the best orientation for the L-bar bracket, install the anchors, and mount the bracket.

Attach the prism to the bracket, rotate it to face the AMTS, and tighten the mounting screw.

Offset of a Leica prism

Similarly, if you are working with a 0mm offset prism (or reflective tape), you will need to add 34mm. You get the idea. Remember, with a Leica instrument the Prism Constant Field is actually the correction you need to enter relative to -34mm, NOT the actual prism constant (offset) of your prism.

How to set prism constants on a Leica lift?

SETTING PRISM CONSTANTS ON A LEICA TOTAL STATION First a primer on Prism Constants (also called Prism Offsets), more correctly called Absolute Prism Constants (APC). Refer to Figure 1 to understand that an EDM needs to be “told” what prism you are using to correctly calculate the distance to the Vertical Axis of the prism.

Overview:

1. High Performance:

Coated optics for better performance.

2. Durable:

Prism is waterproof and dusproof, suitable for any environment.

3. Low Visual Impact:

The compact prisms are almost unnoticeable from street level.

4. Easy Installation:

The compact bracket can be installed in any orientation and fits nearly any location.

5. Cost Effective:

Economical prism provides low cost per monitored point.

Optical Surveying Reflector Prism Applications

Surveying reflector prisms are used by surveyors and engineers to measure the change in position of a target that is assumed to be moving. Survey prisms are used for a wide range of monitoring applications including:

1. Rail Monitoring
2. Settlement Monitoring
3. Displacement Monitoring
4. Deformation Monitoring
5. Convergence Monitoring
