German hydac sensor hydac model hydac price

hydac sensors, also known as linear sensors, are linear devices based on metallic induction. The function of the sensor is to convert various measured physical quantities into electrical signals. In production processes, displacement measurement is generally divided into two types: measuring physical dimensions and mechanical displacement. Depending on 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 physical-property type and structural type. 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. These sensors are developing rapidly and their applications are becoming increasingly widespread.

hydac 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 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. Analog photoelectric sensors can be classified 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, where light energy emitted by a constant light source passes through the object, is partially absorbed, and 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 being projected 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.

hydac 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 relies on light blocking and reflection caused by the 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 circuits consist 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 emitted 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 emitted 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 projecting visible light, the emitted beam is visible to the eye, facilitating adjustment of the detected object's position.

hydac 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, used to measure physical quantities such as light intensity, object temperature, light transmittance, displacement, and surface condition. Examples include lux 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 used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (2) Devices that convert 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 computers, switching temperature control devices, and digital photoelectric tachometers for speed measurement.
