Germany THERMO KING BELGIUM sensor THERMO KING BELGIUM model THERMO KING BELGIUM price

THERMO KING BELGIUM sensor precisely measures the actual displacement of the detected product by detecting the absolute position of the movable magnetic ring through internal non-contact measurement and control technology; the high precision and high reliability of this sensor have been widely applied in thousands of practical cases. Since the movable magnetic ring that determines the position and the sensitive element do not have direct contact, the sensor can be used in extremely harsh industrial environments and is not easily affected by oil stains, solutions, dust or other pollutants. In addition, the sensor uses high-tech materials and advanced electronic processing technology, so it can be used in high temperature, high pressure and high vibration environments. The sensor output signal is an absolute displacement value; even if the power is interrupted and reconnected, data will not be lost, and there is no need to re-zero. Since the sensitive element is non-contact, even with continuous repeated detection, it will not cause any wear to the sensor, which can greatly improve the reliability and service life of the detection.

THERMO KING BELGIUM sensor principle

Optical measurement and control systems are diverse, made according to different principles of the effect of luminous flux 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 categories based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and light-blocking (beam obstruction) type. The so-called transmission type means that the measured object is placed in the optical path, the light energy emitted by the constant light source passes through the measured object, and after being partially absorbed, the transmitted light is projected onto the photoelectric element; the so-called diffuse reflection type means that the light emitted by the constant light source is projected onto the measured object, and then reflected from the surface of the measured object onto the photoelectric element; the so-called light-blocking type means that when the luminous flux emitted by the light source is partially blocked by the measured object, the luminous flux projected onto the photoelectric element changes, and the degree of change is related to the position of the measured object in the optical path.

THERMO KING BELGIUM sensor features

1) Long detection distance: If a detection distance of more than 10m is maintained in the through-beam type, long-distance detection can be achieved that other detection 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 detected objects to metals, it can detect almost all objects such as glass, plastic, wood, liquids, etc. 3) Short response time: Light itself is high-speed, and the sensor circuit is composed of electronic components, so it does not include mechanical operating time, resulting in a very short response time. 4) High resolution: High resolution can be achieved by concentrating the projected 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 can be achieved: Detection can be performed without mechanical contact with the detected object, so it will not damage the detected object and the sensor. Therefore, the sensor can be used for a long time. 6) Color discrimination can be achieved: 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. Using this property, the color of the detected object can be detected. 7) Easy to adjust: In types that project visible light, the projected light beam is visible to the eye, making it easy to adjust the position of the detected object.

THERMO KING BELGIUM sensor applications

Photoelectric sensors using photoelectric elements as sensitive elements are numerous 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 transmission capacity, displacement, and surface status. For example: illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric alarms for fire prevention, and automatic detection devices and instruments for checking the diameter, length, ellipticity and surface roughness of processed parts, all of which use photoelectric elements as sensitive elements. Semiconductor photoelectric elements are not only widely used in the civil industrial field, but also have 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) Convert the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "yes" or "no" 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, etc.
