Laser Distance Meter

Laser class 1

For reflectorless measurement of distance and speed

 

Properties 

The LS1501 laser distance meter measures distance and speed values in a non-contact fashion, also without a reflector. Taking only a very short time to measure, it facilitates distance measurement to or from moving objects.

The laser pulse’s time-of-flight measurement principle which it uses is particularly suitable where great distances have to be measured or operation is linked to harsh industrial environments.

Of compact design shape, simple setup and configured with standard interfacing facilities, the LS1501 can easily be installed and commissioned.

For interfacing, RS232, RS422, SSI and Profibus are available.

Standard LS1501 delivery includes integral heating, a status display and a sighting device.

A modular setup allows for easy complementation with accessories or special models as may be required in particular applications.

 

Benefits

 

• Broad working range

• Great reach, also without reflectors

• Very short times to measure

• Allows synchronisation with external devices

• Compact design shape

• Easy to install and operate

 

Applications

 

Equipment and performance features of the LS1501 warrant multiple possibilities of application in industrial environments:

 

• Process monitoring in steel works and rolling mills

• Fill-level measurement

• Positioning of cranes, loading and handling equipment

• Measurement of points that cannot be accessed, for example, inside of cavities, tubes or containers

• Position monitoring of vehicles or ships
