Voltage sensor refers to a sensor that can sense the measured voltage and convert it into a usable output signal, in a variety of detection and control systems, it is often necessary to track and collect the communication DC voltage signal that changes at high speed, and do spectrum analysis on some more complex voltage waveforms. Voltage Sensors ...

Depending on the resolution supported by the encoder, encoders can be divided into marker encoders, HD encoders, and Full HD encoders. The higher the frame rate, the clearer the video. 1. What does the resolution of the encoder mean? The resolution of the encoder refers to the encoder passing through a line or a dark line (also ...

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

1. Shielding technology The use of metal materials to make a container, the circuit that needs to be maintained is wrapped in it, which can effectively avoid the disturbance 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 ...

Ultrasonic flow sensor is a new type of general-purpose time-difference multi-function ultrasonic sensor suitable for industrial environments, mainly using low-voltage multi-pulse balanced emission acceptance technology, which can be mainly applied to measure the flow of most clean and uniform liquids without large concentrations of suspended particles or gases.

Humidity sensors are divided into resistive and capacitive types, and the basic form of the product is to coat the substrate with moisture-sensitive materials to form a moisture-sensitive film. After the water vapor in the air is adsorbed on the moisture-sensitive material, the impedance and dielectric constant of the element are greatly changed, so as to make a moisture-sensitive element. ...

First, the selection of its primary consideration for the selection of three points: how wide the groove width should be; resolution (slit width); Fixation 1. The width of the slot, the detection object needs to pass through the slot of the slot-type optocoupler to block the infrared light, so the slot width of the photoelectric sensor should be wider than the detection object, and there should be a certain ...

Proximity switches Proximity switches are a reliable and proven solution for the detection of correct and wrong contacts. Photoelectric sensors Photoelectric sensors use a pair of luminaires and receivers to detect distances and detect the presence of objects. ...

Cover the safety light curtain with your hands and observe whether the indicator light conversion is normal. During the use of the punch photoelectric protection device, the orientation of the photoelectric protection device shall not be changed at will. In the protection zone, the light curtain should be blocked by hand, and the machine should be able to stop the operation immediately. ...

Modular power supplies are power supplies that can be mounted directly on a printed circuit board and feature power supply to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field-programmable gate arrays (FPGAs), and other digital or analog loads. One...

1. Long detection interval. By retaining an inspection interval of more than 10 m in the through-beam model, other inspection methods can be accomplished. 2. Less detection of objects. Because the detection of shading and reflection caused by the object is the detection principle, it is not like the proximity sensor to limit the detection of the object to the metal ...
