Proximity sensor design considerations – a blessing on our part

The use of robots that can exchange things requires high-speed movement and fast rotation. Conventional solutions for energy chains or slip rings lack the necessary flexibility with regard to this automation technology. Our wireless sensing system (WIS) enables non-contact in places where a fixed connection is not possible.

A gas sensor is a converter that converts the volume fraction of a gas into an electrical signal. When we use gas sensors, we will inevitably encounter some problems, in this regard, we have made the following analysis: 1. Gas sensing ...

An encoder is a device that compiles or converts signals or data into signals that can be communicated, transmitted, and stored. The encoder converts angular or linear displacement into an electrical signal. Fault Symptom: 1. The encoder itself ...

Now that the prevention and control of the new pneumonia epidemic has entered a critical period, how can it be useful to reduce cross-infection in hospitals and prevent the spread of the epidemic? Reduce the operational pressure of front-line medical personnel and help prevent and control the epidemic? All of them have become the key policies that have attracted wide attention. From long-distance medical care to intelligent robots ...

The working principle of the straight line is the same as that of the sliding rheostat, it is used as a voltage divider, it is the actual orientation of the measured direction with the relative output voltage. There are the following requirements for the operation of this equipment: 1 ...

Measurement accuracy generally refers to the affirmative accuracy of the measurement value of the analog output. Depending on the echo transmission moment, the measurement accuracy of the ultrasonic sensor relies on several physical parameters. These parameters are generally related to air and internal errors. Environment...

The safety barrier, also known as the safety factor meter, is an important part of the intrinsic safety system. 　　There are two main types of barriers: P+F Zener barriers and P+f isolated barriers. The core elements of a double Forgina barrier are a diode, a current-limiting resistor and a fast fuse. ...

Unlike load cells or force transducers, the measuring body of a torque transducer is not subjected to a tension load during operation, but is affected by the lever torque or torque, which can be changed. Therefore, torque sensors require special strain gauges to measure this type of load, i.e. torque. Canon...

There are two common types of sensor switches: NPN type and PNP type, so what are the differences and differences between them? For example, there is a switch VT in the NPN open collector output circuit, and the output OUT is through the switch ...

The pulse encoder is a rotary encoder that uses the rotation pulse for signal output, and the main characteristics are the standard shape and diversified shape structure; The internal coding is stable, the signal output qiang, and the pulse value and positioning value are clear. Therefore, when choosing this type of punching encoder, ...

P+F photoelectric proximity switch is called a photoelectric switch made of the photoelectric effect. The light-emitting device and the photoelectric device are installed in the same detection head in a certain direction. When a reflective surface (the object to be detected) is close to each other, the photoelectric device receives the reflected light and outputs it in the signal, so that it can be "...

In order to select the best liquid level sensor, we need to understand not only the characteristics and state of the liquid to be measured, but also the advantages and limitations of different detection methods, so as to be able to select the most suitable sensor. Here are some of the most common detection technologies on the market today. ...

In the early application and selection of sensors, how to choose is a very important point, and the selection is smooth, and the following will briefly say how the sensor is selected in the early stage. The Viewpoint Sensor is in the real ...

Strain gauge tension and compression load cells are available in two different input and output wiring methods: The first is the four-wire connection method. The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and it is very convenient to use, but when the cable is long, it is easy to be shaken by the operating temperature.

First, the first component blocking may be the wrong way of the device, the pressure point is unreasonable, so we often emphasize that the device must be the correct device, once the installation is wrong, maybe the installation is not good, it will bury endless hidden dangers for the back. What are the primary components? Orifice plates, remote transmission measuring joints, etc.

According to the nature of the measurement, sensors can be divided into three categories: physical sensors, chemical sensors and biosensors. Physical sensors: It is the use of certain physical effects to convert the measured energy into energy that is easy to process.

1. Shielding skills Containers are made from metal materials. Wrapping circuits that require maintenance between them can effectively prevent the disturbance of electric or magnetic fields, which is called shielding. Shielding can be divided into electrostatic shielding, electromagnetic shielding and low-frequency magnetic shielding. 2. Electrostatic shielding ...

The rotary incremental encoder outputs pulses when it rotates, knows its orientation by the counting device, and remembers the orientation by relying on the internal memory of the counting device when the encoder does not move or the power goes out. In this way, when the power goes out, the encoder can not have any movement, and when the call is working, the encoder ...

Auxiliary mechanical devices: commonly used are rack and pinion, chain belt, friction runner, rope reeling machinery, etc. Low-speed end device: installed behind the reduction gear, such as the shaft end of the winch wire rope drum or the shaft end of the next reduction gear ...

What is the reason for the detection signal when no metal object is close to the switch? The magnitude of the electromagnetically induced voltage is proportional to the current of the disturbance source, that is, the larger the disturbance current, the greater the disturbance voltage. If the proximity switch does not adopt any ...
