Product Description

The KLSA series laser ranging sensors for surveying and engineering construction.

Introduction 

The KLSA series laser ranging sensors are specialized tools designed to meet the rigorous demands of surveying and engineering construction. Built with advanced laser technology, these sensors deliver high-precision, non-contact distance measurements to support tasks such as site planning, structural alignment, and progress monitoring in construction environments.

Key Features

  • Precision Measurement: Accurately measures distances from 0.03 to 22 meters, with a fixed accuracy range and millimeter-level resolution (e.g., 1.234m for sub-10m readings), ensuring detailed data for surveying and layout tasks.
  • Dual Signal Output: Provides RS485 (MODBUS-RTU protocol) for digital integration with surveying software and 4–20mA analog signals for real-time data transmission to control systems.
  • Background Suppression: Filters reflections beyond 22 meters, minimizing interference from surrounding structures or terrain to focus on target measurements.
  • User-Configurable Interface:
  • Intuitive 4-digit display shows real-time distance readings in meters, with automatic unit switching (millimeters for <10m, centimeters for ≥10m).
  • MODE/SET buttons enable on-site adjustments, such as laser on/off control (via LAS menu) and analog range calibration (AEP setting), without disrupting measurements.
  • Hysteresis & Window Functions (KLSA-PN Model):
  • Hysteresis function stabilizes output signals by defining switch points with ±30mm tolerance, ideal for monitoring moving components in dynamic construction sites.
  • Window function sets near (nSPx) and far (FSPx) thresholds to detect objects within specific zones, supporting quality control for structural gaps or material placement.
  • Industrial-Grade Reliability:
  • Operates on DC 9–35V power supply, compliant with EN 50178 safety standards, and withstands harsh site conditions with rugged construction.
  • Requires professional installation to ensure compliance with safety regulations and optimal performance.

Applications

  • Surveying & Mapping: Measures land contours, building dimensions, and infrastructure clearances for topographic analysis and design.
  • Construction Site Monitoring: Tracks structural deformations, checks formwork alignment, and verifies material stockpile volumes in real time.
  • Civil Engineering: Supports bridge and tunnel construction by monitoring component spacing, vertical/horizontal alignment, and load-bearing clearances.
  • Equipment Integration: Integrates with robotic total stations, drones, or IoT systems via MODBUS-RTU for automated data collection and workflow optimization.

Technical Specifications

Communication: Isolated RS485 with adjustable baud rates (9600–115200 bps) and CRC16 check for reliable data transmission.

Safety: Laser on/off control reduces visual interference during surveys, while fault status registers (e.g., 0000H for over-range alerts) enhance diagnostic capabilities.

The KLSA series combines precision, durability, and adaptability, making it an indispensable tool for professionals in surveying and engineering construction who require reliable, real-time distance measurement solutions.
