Air pressure sensor principle and precautions

We offer a wide range of barriers for different requirements. Barrier and Zener barriers are available to ensure the safe transmission of signals in hazardous areas. Barrier barriers In addition to the explosion-proof function, the barrier ...

1. The safety barrier should be installed in a safe place, and the environmental conditions should meet the requirements of the "application conditions" in the "Safety Barrier Selection Sample". 2. The connecting wires of the intrinsically safe end (blue end) and non-intrinsically safe end circuits of the barrier safety barrier are in the sink ...

Photoelectric switches are what we generally call sensors. The definition of the sensor under the national standard GB7665-87 is: the equipment or device that can feel the specified measured parts and convert them into usable signals in accordance with certain rules, generally composed of sensitive elements and conversion elements. ...

The new RHI90 series encoders offer significant improvements in electrical and mechanical performance With the extensive use of electronic components and equipment in the field of automation, the risks of malfunction and damage caused by electrical and electromagnetic disturbances are also invisible.

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

1. The temperature and humidity sensor will drift during use, which is impossible to avoid. 2. The fundamental reason for the drift is that all pressure sensors are based on the elastic deformation of a kind of material, no matter how outstanding the elasticity of the raw material is, after each elastic recovery, there will always be ...

A pressure transmitter is a type of instrument that converts a pressure variable into a consistent output signal that can be transmitted, and there is a given continuous function relationship between the output signal and the pressure variable, which is generally a linear function. Pressure variables include positive and negative pressure, differential pressure and pressure. Pressure transmitters are available in electric and ...

In the process of modernization, the SLP series is gradually forming a modular safety system, constantly innovating, and requiring more stringent quality on the basis of innovation. VISOLUX offers safety light curtains for a wide range of light beams. These self-monitoring lights ...

1. Avoid scum deposited in the catheter and contact the transmitter with corrosive or overheated media. 2. When measuring the gas pressure, the pressure port should be opened at the top of the process pipeline, and the transmitter should also be installed at the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process.

There are two main types of encoders, incremental encoders and affirmative encoders. The incremental encoder reads the change in the viewpoint displacement, while the affirmative encoder reads the positive viewpoint of the encoding axis. They are done using three common skills, i.e., optical, mechanical, or magnetic. ...

An important function of the photoelectric switch is to be able to handle changes in the intensity of light: the light beam is changed by using optical components in the transmission medium; Use a beam of light to reflect objects; Instantaneously returns the light emitted by the beam over a long distance. 　　The photoelectric switch (photoelectric sensor) is a photoelectric proximity on...

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 "...

Optical ranging is based on the principle of triangulation. With this geometric approach, the interval from the sensor to the target can be accurately measured by changing the viewpoint within the triangle. The super light source emits a beam to the target object, and then ...

First of all, the following points should be paid attention to when wiring the encoder: 1. It is necessary to use a metal cable bracket and ensure that the bracket connection is connected to the ground; 2. The cable should be arranged as close to the metal parts as possible, such as control cabinet panels, beams and metal rails, etc.

1. Encoder self-failure: It refers to the failure of the encoder's own components, resulting in its inability to generate and output correct waveforms. In this case, the encoder needs to be replaced or the internal equipment repaired. 2. The encoder connection cable is faulty ...

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 ...

One. First of all, we need to have a brief understanding of rotary encoders Rotary encoders can be used to measure rotational velocity, acceleration, azimuth and direction. Encoders can be used in a wide range of mechanical engineering occupations, such as material handling, logistics and packaging. In the field of industrial automation ...

The dynamic characteristics of a sensor refer to the characteristics of the output of the sensor when the input changes. In practice, the dynamic characteristics of the sensor are often indicated by its echo to some normative input signals, because the echo of the sensor to the normative input signal is easy to obtain by experimental methods, ...

On the linear scale of our sensors, the higher the sensitivity, the better. Because only when the sensitivity is high, the value of the output signal corresponding to the measured change is relatively large, which is conducive to signal processing. However, it should be noted that the sensitivity of the sensor is high, and the external noise that is not related to the measurement is also simple.
