Laser sensor operation mechanism
Laser sensors with their unique capabilities are currently in the industry looking for a place for various measurements such as distance and even the presence or absence of objects and in advanced models for three-dimensional scanning of objects.
The unique capabilities of slippery sensors such as high point response speed, as well as very high repeatability and accuracy, as well as background light make it necessary to use this sensor in cases with long distances and high accuracy or limited access.
To choose Lizzy sensors, it is necessary to pay attention to the following points:
Lysine sensors with different power and strength are designed for various applications. The two main applications of Lysine sensors in the distance finding industry are detection of presence or absence.
In models that have a discrete output and function such as proximity and pragmatic sensors, PNP or NPN should be considered, which is selected according to the type of controller used.
Laser sensors that are used for distance measurement have continuous or analog output and in some cases have network and bus output. They should be ordered according to the type of output, which is 4 to 20 mA signals or voltage, depending on the user's needs.
In the case of distance measurement, two factors, the range of the measured distance and the accuracy and resolution of the measurement, are of great importance.
Lysine sensors are made with different technologies, the most widely used of which are models with a triangular p
attern that in most cases do not require a reflector, but at the same time many of these sensors with a reflector are used in a wider range and with greater accuracy. The choice of models should also be considered.
Other factors such as operating temperature and humidity as well as pressure or the use of explosion-proof sensors in explosion environments are also parameters that should be considered in choosing a laser sensor.
