German marposs sensors marposs models marposs prices

marposs sensors are sensors that measure the operating speed of the measured object and convert it into an output signal. Speed sensors include linear speed sensors and rotational speed sensors. With the development of technology, traditional measuring equipment can no longer meet current needs and is gradually being eliminated, while laser speed sensors have been widely used. They play an important role in the product production process. By connecting to a computer, they enable automated and intelligent measurement and control of the measured object. This is the product of the combination of modern measurement technology and computer technology.

marposs sensor principle

Optical measurement and control systems are diverse, manufactured based on different principles of how luminous flux acts on photoelectric elements. According to the nature of the output of the photoelectric element (optical measurement and control system), they can be divided into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured quantity into a continuously changing photocurrent, which has a single-value relationship with the measured quantity. Analog photoelectric sensors can be divided into three major types based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and light-blocking (beam obstruction) type. The transmission type refers to placing the measured object in the optical path; the light energy emitted by a constant light source passes through the measured object, and after partial absorption, the transmitted light is projected onto the photoelectric element. The diffuse reflection type refers to the light emitted by a constant light source being projected onto the measured object, and then reflected from the surface of the measured object onto the photoelectric element. The light-blocking type refers to the measured object blocking part of the luminous flux emitted by the light source, causing a change in the luminous flux projected onto the photoelectric element; the degree of change is related to the position of the measured object in the optical path.

marposs sensor features

1) Long detection distance: If a detection distance of 10m or more is maintained in through-beam configurations, it enables long-distance detection that other methods (magnetic, ultrasonic, etc.) cannot achieve. 2) Few restrictions on detected objects: Since the detection principle is based on light blocking and reflection caused by the detected object, unlike proximity sensors that limit detection to metals, it can detect almost all objects such as glass, plastic, wood, and liquids. 3) Short response time: Light itself is high-speed, and the sensor circuit consists of electronic components, so there is no mechanical operating time, resulting in a very short response time. 4) High resolution: High resolution can be achieved by concentrating the emitted light beam into a small spot through advanced design technology, or by constructing a special light-receiving optical system. It can also perform detection of tiny objects and high-precision position detection. 5) Non-contact detection: Detection can be performed without mechanical contact with the object, so neither the detected object nor the sensor will be damaged. Therefore, the sensor can be used for a long time. 6) Color discrimination: The reflectance and absorptance of light formed by the detected object vary depending on the wavelength of the emitted light and the color combination of the detected object. Using this property, the color of the detected object can be detected. 7) Easy adjustment: In types that project visible light, the emitted light beam is visible to the eye, facilitating adjustment of the position of the detected object.

marposs sensor applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. According to the nature of the output of the photoelectric sensor, they can be divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent can be used to measure physical quantities such as light intensity, object temperature, light transmittance, displacement, and surface condition. For example: illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric alarms for fire prevention, and automatic inspection devices and instruments for checking the diameter, length, ovality, and surface roughness of machined parts, all of which use photoelectric elements as sensitive components. Semiconductor photoelectric elements are not only widely used in civil industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be made into infrared night vision devices, infrared cameras, and infrared navigation systems; (2) Converting the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "on" or "off" electrical signals when exposed to light or no light. Photoelectric elements are used as switching photoelectric conversion elements. For example, photoelectric input devices for electronic computers, switching temperature regulation devices, and digital photoelectric tachometers for speed measurement.
