1: Preface
The "Chengtuo" series laser ranging sensors produced by our company are a new generation of non-contact, high-precision ranging sensors. It is powerful in function, sturdy in structure, and designed specifically for industrial and field use. Suitable for long-term online monitoring use, and our company provides free online monitoring system solutions to guide construction, etc.Our company's products are self-developed and can be customized for customers based on their functions.
The laser ranging sensor is a laser ranging product with a laser level of Level 2 safety. When using it, please do not direct it directly to your eyes or direct it towards sunlight. This sensor also has digital interfaces (RS232, RS485, RS422), analog interfaces (0-5V, 0-10V, ± 5V, ± 10V, 4-20mA, 0-20mA, 0-24MA), and switch quantity interfaces (passive switch interfaces, maximum load can reach 24V 0.5A). The warranty period for this sensor is one year, with lifetime maintenance.
2: Overview
GHLM-07BThe laser ranging sensor is a new type of motion monitoring sensor, specifically designed to measure the position of small moving or moving objects.
Main features:
uHigh measurement accuracy and reliability can still be maintained in outdoor environments.
uSensors can be processed to be fully sealed, making them convenient for use in harsh environments.
uDC power supply, with a wide range of power supply (from 12V to 24V). It can be powered by car power supply, industrial grid voltage or DC power supply.
uStable power consumption, minimal power consumption (less than 1.5W in the absence of current alarm).
uThe farthest measurement range can reach 150 meters, and the minimum measurement can be 5 centimeters.
uUsing a visible laser beam with a small divergence angle, the laser spot is only 150 millimeters at a distance of 150 meters.
uExternal triggers can be used to remotely trigger measurements.
uFlexible and expandable connection cables facilitate power supply, bidirectional data transmission, switch and analog output.
uThe starting point for distance measurement can be set as the front and rear ends.
uIn the continuous measurement state of the sensor, the data return time interval can be freely adjusted within the range of 0.1S to 105S.
uThe digital interface forms of sensors include RS232, RS422, and RS485, which can be switched freely.
uThere is a matching wireless module that can be remotely controlled using wireless communication methods such as 3G, Bluetooth, Zigbee, etc
uThere are four voltage and three current output modes for analog output. The analog output value can correspond to any distance and can also be output in reverse. Convenient for direct access to PLC, secondary instruments and other equipment.
uThe switch output point and switch output status can be adjusted through commands or matching parameter setting software. Has a carrying capacity of 1A.
uEach sensor has a uniqueserial number, can be read through commands.
3: Safety Notice
The maximum power of the laser in the laser ranging sensor is 1mW. The laser level is level 2 and complies with IEC825-1/DIN EN60825-1:2001-11 and FDA21CFR regulations. If an accident occurs and the human eye is exposed to laser light for a short period of time (greater than 0.25 seconds), the human eye can be protected by the blink reflex of its own eyelids. The blink reflex of a person can effectively protect their eyes.
Although the product may not require specialized safety protection devices, it is still necessary to avoid direct viewing of the laser beam as much as possible. Do not aim the laser beam directly at the human body. Sensors can be used without any protective measures.
Application precautions:
uAiming at the sun or other strong objects for measurement may result in incorrect results.
uMeasuring objects with poor reflective surfaces in strongly reflective environments can also produce incorrect results.
uMeasuring strongly reflective surfaces can produce incorrect results.
uMeasurement through transparent objects such as glass, optical filters, and resin glass may result in incorrect data.
uRapidly changing the measurement environment can also generate false data.
