Germany ATW SA sensor ATW SA model ATW SA price

ATW SA sensors, also known as linear sensors, are linear devices based on metal induction. The function of the sensor is to convert various measured physical quantities into electrical signals. In the production process, displacement measurement is generally divided into two types: measurement of physical dimensions and mechanical displacement. According to the form of transformation of the measured variable, displacement sensors can be divided into analog and digital types. Analog types can be further divided into property-based and structural types. Commonly used displacement sensors are mostly analog structural types, including potentiometric displacement sensors, inductive displacement sensors, synchros, capacitive displacement sensors, eddy current displacement sensors, Hall effect displacement sensors, etc. An important advantage of digital displacement sensors is that they facilitate direct input of signals into computer systems. This type of sensor is developing rapidly and its applications are becoming increasingly widespread.

ATW SA sensor principle

Optical measurement and control systems are diverse, developed based on different principles of how luminous flux acts on photoelectric elements. According to the nature of the output from 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, exhibiting a single-valued relationship with the measured quantity. Based on the method of measuring the target object, analog photoelectric sensors can be divided into three main categories: 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 light from a constant source being projected onto the measured object, reflecting off its surface, and then projecting onto the photoelectric element. The light-blocking type refers to the measured object obstructing part of the luminous flux from the light source, thereby changing the luminous flux projected onto the photoelectric element; the degree of change depends on the position of the measured object in the optical path.

ATW SA sensor features

1) Long detection distance: If a detection distance of more than 10m 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 object, unlike proximity sensors which 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 circuitry consists entirely of electronic components, so there is no mechanical operating time, resulting in very short response times. 4) High resolution: Advanced design technologies allow the projected light beam to be focused into a small spot, or special receiving optical systems can be constructed to achieve high resolution. This allows for the detection of tiny objects and high-precision position detection. 5) Non-contact detection possible: Detection can be achieved without mechanical contact with the object, thus causing no damage to the detected object or the sensor. Therefore, the sensor can be used for a long time. 6) Color discrimination possible: The reflectance and absorptance of light formed by the detected object vary depending on the wavelength of the projected light and the color combination of the detected object. Utilizing this property, the color of the detected object can be determined. 7) Easy adjustment: In types that project visible light, the projected beam is visible to the eye, facilitating adjustment of the detected object's position.

ATW SA sensor applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. According to the nature of the output from 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. Examples include 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, ellipticity, and surface roughness of machined parts, all of which use photoelectric elements as their sensitive components. Semiconductor photoelectric elements are not only widely used in civilian industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be used to make 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 serve as switching photoelectric conversion components. Examples include photoelectric inputs for electronic computers, switching temperature regulation devices, and digital photoelectric tachometers for speed measurement.
