Banner Sensor - The appearance of a fiber optic sensor

1. Photoelectric smoke alarm When there is no smoke, the light emitted by the light-emitting diode travels in a straight line, and the phototriode does not receive a signal. There is no output, when there is smoke, the light emitted by the LED is refracted by the smoke particles, so that the transistor receives the light, there is a signal output, ...

1. Shielding technology Containers are made of metal materials. Wrapping the circuit that needs to be protected in it can effectively prevent the interference of electric or magnetic fields, and this method is called shielding. Shielding can be divided into electrostatic shielding, electromagnetic shielding and low-frequency magnetic shielding. 2. Electrostatic shielding ...

1. The problem of the sealing ring of the pressure sensor The output of the pressurized transmitter does not change, and the output of the pressurized transmitter changes suddenly, and the zero position of the pressure relief transmitter cannot be returned, which is likely to be a problem with the sealing ring of the pressure sensor. It is common that due to the specification of the sealing ring, the sensor is tightened and tightened.

When choosing a pressure sensor, we need to consider its comprehensive accuracy, and what are the aspects that affect the accuracy of the pressure sensor? In fact, there are many factors that cause sensor error, and we will pay attention to four unavoidable errors, which are the initial error of the sensor. Head...

Depending on how the actuator acts, there are three most common types of emergency stop switches. Pull Release: Push in the actuator to stop and release by pulling the actuator backwards. Torsional Release: Push the actuator in by torsional actuator to stop and release. Key Release: Perform ...

The three foundations of modern information technology are information collection (i.e., sensor technology), information transmission (communication technology), and information processing (computer technology). Sensors belong to the cutting-edge products of information technology, especially temperature sensors are widely used in industrial and agricultural production, scientific research and life.

The Internet of Things (IoT) is a network based on information carriers such as the Internet and traditional telecommunication networks, which allows all ordinary objects that can perform independent functions to achieve interconnection. Its application fields mainly include transportation and logistics, industrial manufacturing, health care, intelligent ...

(1) When the grating ruler displacement sensor is connected to the digital display table, the power must be cut off, and the power supply will be provided after the plug is linked. (2) The grating ruler displacement sensor should prevent foreign objects from entering its interior, including water, oil, dust, etc., so a protective cover should be installed as much as possible outside. (3) Periodic inspection ...

1. Piezoresistive pressure sensor Resistive strain gauges are one of the main components of piezoresistive strain transducers. The working principle of metal resistance strain gauge is the phenomenon that the resistance value changes due to mechanical deformation due to the strain resistance adsorbed on the base material, which is commonly known as the resistance strain effect. ...

1. Microwave and RF environments 2. Nuclear energy and hazardous environments 3. High temperature and high pressure environment 4. Online monitoring 5. Aerospace applications 6. Civil engineering and geotechnical applications 7. Materials Science ...

1. If the electronic ruler has been used for a long time, and the seal has been aged, and there are many impurities mixed with it, and the water mixture and oil will seriously affect the contact resistance of the brush, which will make the displayed numbers keep jumping. At this time, it can be said that the electronic ...

The progress of industrial automation and intellectualization has enabled human beings to gradually liberate themselves from heavy manual labor, and the emergence of machine tools and machining centers has enabled machines to complete the processing of parts faster and more accurately, and the emergence of automatic loading and unloading systems has made the machining center more powerful. And the loading and unloading ...

1. Long detection distance If the detection distance of 10 m or more is retained in the through-beam type, it is possible to achieve detection that is not possible with other detection methods (magnetic, ultrasonic, etc.). 2. There are few restrictions on the detected objects Due to the detection of shading and reflection caused by the detection of objects ...

The first point is that photoelectric sensors and fiber optic sensors work differently First of all, from the working principle of the two, first of all, the photoelectric sensor works according to the principle of the photoelectric effect, that is, when the light hits the photoelectric sensor made of semiconductors, it will emit light ...

1. Application in infrastructure engineering Internet of Things In the process of construction and use of major projects such as highways, bridges, tunnels and buildings, there are often local collapses, leaks and fires in tunnels, local cracks and collapses in bridges, which not only seriously threaten people's lives and property.

The sensor is a kind of detection device, which can feel the measured information, and can transform the felt information into electrical signals or other required forms of information output according to a certain law, so as to meet the requirements of information transmission, processing, storage, display, recording and control. Photoelectric sensors and ...

The static characteristics of a sensor refer to the performance of the sensor in a static state, which is an important indicator to measure the sensor. The static characteristics of a sensor include linearity, repeatability, hysteresis, accuracy, sensitivity, threshold and resolution, drift, and more. 1. Linearity refers to the sensor measurement ...

1. The use of ultrasonic spacer sensor skills An ultrasonic sensor consists of three parts: an ultrasonic transducer, a processing unit, and an output stage. First, the processing unit excites the ultrasonic transducer with voltage, and after it is excited, it announces the ultrasonic wave in the form of pulses, and then the ultrasonic transducer is transferred to withstand ...

High sensitivity Lightweight and flexible, easy to install and buried Electrical insulation and chemical stability. Optical fiber itself is a highly insulating and chemically stable substance, which is suitable for harsh environments such as high-voltage isolation and flammable and explosive in power systems and chemical systems Good security ...

1. The magnetic tape can be directly pasted on the surface of the equipment, and the two ends are fixed with screws; 2. The magnetic tape can be directly installed in the reserved groove; 3. The magnetic tape can be pasted in the aluminum alloy protective shell provided by the manufacturer, and then the magnetic ruler can be fastened to the equipment with the mounting bracket. ...
