1. Introduction
The LM-SD is a laser based distance measurement tool used to measure distances from
0.2m to more than 100m with pinpoint accuracy. A given target can be clearly identified
with the help of a red laser sighting point. The usable range of the sensor is dependent
upon target physical properties.
The range finder is based on comparative phase measurement. It emits high-frequency
modulated light which is diffusely reflected from the target and returns to the instrument
with a certain phase shift compared with the emitted signal. The distance can then be
determined with millimeter accuracy from the amount of this phase shift
Special performance features are:
- Provides high accuracy over long distances under extreme outdoor temperatures.
- Works in a wide range of operating voltages from 10 VDC to 30 VDC
- Features consistently low power consumption of <1.5 W (without IAlarm).
- Up to 30m range for distance measurement, with the potential for more than 100m
if additional reflectors are mounted onto the target (depending on reflectance and
environmental conditions).
- Visible laser beam for easier sighting.
- Switching output and analog output are separately programmed.
- Switching output tied to adjustable limits, indicating positive and negative over-range of
pre-selectable distance range window.
- Measured values can be displayed in meters, decimeters, centimeters, feet or inches.
