German SZW PROPHET sensors, SZW PROPHET models, SZW PROPHET prices

SZW PROPHET 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 technological development, traditional measuring equipment can no longer meet current needs and is gradually being phased out, while laser speed sensors are widely used and play an important role in product manufacturing. 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.

SZW PROPHET sensor principle

Optical measurement and control systems vary based on the different principles of how luminous flux acts on photoelectric elements. Based on the nature of the output from the photoelectric elements (optical measurement and control systems), 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 types based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and light-blocking (beam interruption) type. The transmission type refers to placing the measured object in the optical path; light energy emitted by a constant light source passes through the object, and after partial absorption, the transmitted light strikes the photoelectric element. The diffuse reflection type refers to light from a constant source striking the measured object and then reflecting off its surface onto the photoelectric element. The light-blocking type refers to the scenario where the measured object blocks part of the luminous flux from the light source, causing a change in the luminous flux reaching the photoelectric element; the degree of change depends on the position of the object in the optical path.

SZW PROPHET 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 travels at high speed, and the sensor circuitry consists entirely of electronic components, eliminating mechanical operation time, resulting in very short response times. 4) High resolution: Advanced design techniques focus the emitted beam into a small spot, or specialized receiving optical systems are constructed to achieve high resolution. This allows for the detection of tiny objects and high-precision position detection. 5) Non-contact detection: Detection is achieved without mechanical contact with the object, preventing damage to both the object and the sensor, thereby ensuring long-term sensor use. 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 of the object. Utilizing this property, the color of the object can be detected. 7) Easy adjustment: In types emitting visible light, the beam is visible to the eye, facilitating adjustment of the object's position.

SZW PROPHET sensor applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. Based on the nature of the output, they are 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, translucency, displacement, and surface condition. Examples include lux meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric fire alarms, 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 in darkness. Photoelectric elements serve as switching photoelectric conversion components. Examples include photoelectric input devices for computers, switching temperature control devices, and digital photoelectric tachometers for speed measurement.
