Industrial production often use transmitters, such as pressure transmitters, temperature transmitters, liquid level transmitters, etc., but the standard signal of these transmitter class is clear? Pressure transmitter class standard signal transmission why is 4 ~ 20mA, rather than 0 ~ 20mA?
In the process of burning coal in thermal power plants, a large amount of coal ash is generated. This coal ash is usually collected in coal ash bins and coal ash hoppers. In order to avoid the stored coal ash from bubbling up the tank, it is quite necessary to detect and control the height of the coal ash material level.
Ultrasonic transducer, also known as ultrasonic probe, is a key component of the ultrasonic level meter, and it is not too much to say that it is the "heart" of the ultrasonic level meter. The ultrasonic transducer converts high-frequency high-voltage power into high-frequency mechanical vibration, and the maximum power output can reach several kilowatts, so the stability and power output of the ultrasonic transducer plays a very important role in the performance of the ultrasonic level transmit
Liquid level alarm switch is widely used in water conservancy, chemical, environmental protection, food and pharmaceutical industries, etc. It is a liquid level measuring instrument specially designed for vessels, tanks and various pipelines.
The guided wave radar level meter has a different working principle compared to other radar level meters and has its own advantages and shortcomings. It is very important for users, especially purchasers, to know this information for proper selection. Below, the principle and advantages and disadvantages of the guide wave radar level meter are described below.
With the development of RF level detection technology, capacitive products have gradually developed into conductive products, which can be used to measure the level of media in containers under different working conditions. However, from the communication with users, many users still know little about the principle of RF Admittance and RF Admittance level switch, and they do not know how to select the correct type.
The mini tuning fork switch, also known as the compact tuning fork level switch, is relative to the tuning fork level switch. At present, small tuning fork switches mainly include compact tuning fork level switches and high-temperature compact tuning fork level switches. So why develop small tuning fork switch when there is tuning fork switch?
"Wire system" is a term often encountered in the automation industry, referring to the number of emergency pull-wire switches used for instrument power supply and standard signal transmission. The title of multi-wire system came into being after the birth of two-wire transmitter. So, what is the two-tier system? What are its advantages?
Remote magnetic flap level gauge is a kind of liquid level measuring instrument which is composed of reed tube remote transmitter and magnetic flap level meter combined together. It transmits the level signal from the site to the machine room or control room in the form of 4-20mA current, so as to grasp the level of the tank remotely and facilitate the purpose of real-time control. In order to better understand the remote magnetic flap level meter, this paper introduces the main uses and daily m
There are two main purposes of material level measurement: first, to determine the quantity of materials in the container through material vibrating fork level measurement to ensure the continuous supply of materials required in all stages of production; The second is to know whether the material level is within the specified range through material level measurement, so as to ensure the normal production process and ensure the product quality, output and production safety.
The plastic type magnetic flap level meter is a commonly used anti-corrosion type magnetic flap level meter. With the same range, the weight of plastic flap level meter is lighter, which certainly makes the installation on site easier. So, in addition to the weight advantage, what are the other advantages of the plastic type magnetic flap level gauge? What are the main applications?
