PL1

Highlights

• Suitable for first order geodetic applications
• Coincidence type optics gives sharp bubble image
• Objective optical wedge provides easy and fine adjustment of line sight
• Optical tooling and industrial alignment application

High performance giving the highest possible accuracy

The PL1 first order precision level was developed after long and through research into every aspect of use under all possible working conditions.

Tilting screw mechanism for fine adjustment

The tilting screw used to level the line of sight is engraved with graduations that accurately indicate the inclination, and index lines that indicate the number of turns of the tilting screw. The tilting screw is divided into 50 equal divisions, each equaling 2" of inclination.

Coincidence type optics give sharp bubble image

Innovative optical design has been used in the coincidence bubble reading optics to ensure a sharp image of the bubble which is magnified to twice normal size.

Optical micrometer allows precise reading

the PL1 is equipped with an optical micrometer which enables staff graduations to be subdivided directly to 0.1mm, and to 0.01mm by estimation. The micrometer knob is turned until the graduation line on the staff bisects the wedge-shaped reticle lines of the PL1 telescope. the shift is numerically displayed in the optical micrometer window, and this reading is added to the staff reading to give direct reading accuracy to 0.01mm.

Wedge shaped reticle for precise reading

the high resolution telescope, which gives a sharp image of the target, is provided with a wedge-type reticle to read staff graduations more accurately. In the distance to the staff can be easily obtained by using the stadia lines.

Optical wedge provides easy and fine adjustment

The adjustment to the line of sight is simple. It is not necessary to adjust screws on the tubular level. Simply turn the optical wedge until the line of sight is horizontal to get exact results.
