Q:What are the differences between a measurement light curtain and a safety light curtain?
A:
Measurement light curtains and safety light curtains are both made up of emitters that emit infrared light, which is then received by receivers to create a light curtain. Therefore, they are essentially the same in function, with the only difference being in terminology. Other terms used include detection gratings and detection light curtains.
Measurement light curtains or measurement gratings are types of photoelectric sensors used for detection and measurement in industries such as industrial, mechanical, and production line fields. They are based on the same principle as safety light curtains, which are a type of through-beam photoelectric sensor. These technologies have emerged as new high-tech industries.
Many people may wonder, what are the differences between a measurement light curtain and a safety light curtain?
A safety light curtain is a safety protection product that, upon detecting a signal, outputs a signal to the controller, causing the operating machine to stop.
A measurement light curtain is an extension of the safety light curtain. Its main purpose is to detect and measure products. It uses data obtained through infrared obstruction to output analog/RS485 signals to the machine. By using algorithms, it can determine the dimensional data of the object being measured.
With the advent of intelligent technology, installing measurement light curtains on equipment can greatly reduce labor costs. Measurement light curtains are a type of photoelectric sensor, similar to ordinary through-beam photoelectric protectors. They consist of separate emitters and receivers in relative positions. They can be used for measuring object size and detecting and measuring the external contour dimensions of objects.
A measurement light curtain is a non-contact detection method where an emitter emits a beam of light that is received, forming a light curtain. Through scanning, in conjunction with a controller and software, it achieves functions and applications such as detection and measurement.
Measurement light curtains utilize beam emission to achieve size detection and have become a reliable non-contact measurement technology. These reliable measurement light curtains can provide better control and detection capabilities. Nowadays, the design of high-quality measurement light curtains highlights the advantages of modern detection technology, and each measurement light curtain design has its own characteristics. Measurement light curtains from Dadi Schenk can be widely used in industries such as industrial, mechanical, and production lines, mainly for detection and measurement purposes. Currently, in the field of measurement light curtains, Dadi Schenk, for example, offers high precision with an accuracy of up to 1.25mm, stable performance, and strong anti-interference ability.
