| Product description |
| |
|
The laser distance measurement module LDM 300 C enables to measure the distance to any
back-scattering target surfaces, without reflector, rapidly and accurately. The used procedure of laser pulse time-of-flight
measurement is particularly suitable for great measurement distances and rough industrial conditions.
The extremely short measuring times enable distance measurements to and from moving objects.
|
|
|
The device is designed for a fixed installation on-site. A light point sight can be mounted to provide an accurate alignement.
A separate box is available for utilisation under extreme conditions.
We offer the comfortable software LDMTool for Windows to configure the laser distance measurement module LDM 300 C.

- Operation in extreme external temperature range with high accuracy and large range
- Large operating voltage range 10 ... 30 V/DC, < 5 W
- Range increase up to more than 1,500 m with additional reflectors on the target object
- Easy aiming at the notch and bead sighting set, far away located objects to be measured can be targeted with the optional light point sight
- Input of commands for the measuring functions and output of the measured values via a PC or laptop
- Separate programming of switching output and analogue output with different parameters
- Adjustable averaging time for distance measurement
- Output of measured values via the serial interface (RS232/ RS422) with free scaling factor
- Class 1 laser according to EN 60825-1:1997-03, eyesafe
