Spectra Precision Laser LR30 Receiver

Rugged 360-degree laser receiver for machine applications

General Description

The Spectra Precision

Laser LR30 Laser Receiver is designed to be used as a

stand-alone display receiver for skid-steer loaders, backhoes, excavators,

dozers and trenchers. Designed for use in harsh environments, the LR30 is

100% weatherproof and features 360-degree laser detection.

Standard Features

• Selectable accuracy—lets you match your application requirements.

Using the right accuracy for the job means clearer feedback to the

operator and less display “jitter.” Work to the tolerances demanded by

the job by selecting the correct on-grade accuracy.

• Selectable on-grade accuracy—allows configuration of the LR30 to

match the job site tolerances.

• Precise laser strike positions—for more accurate grade control.

Unlike other laser receivers that provide only 5 to 7 fixed relative grade regions, the LR30 laser

receiver provides a continuous, absolute laser strike position to precisely measure the actual

height deviation from “On Grade.” This feature gives you the highest accuracy and grade

performance.

• Designed for construction—Shock mounted electronics for stable performance and tough

aluminum/poly carbonate housing for superior knock and drop protection. Sealed housing and

battery chamber is designed and built to the most demanding construction industry standards.

• Receiving Windows—include photocells for laser beam reception.

• Super-Bright LEDs—are highly visible and can be viewed comfortably in any conditions,

including bright sunlight. The green diodes display on-grade information, and the red diodes

graphically display high and low information.

• Touch-Panel—contains power, deadband, and display-brightness buttons. The panel also

displays low-battery warning and deadband selection. Unmarked buttons and button
