Currently, the world is entering a low-carbon era. All governments are vigorously promoting the process of the low-carbon era. Faced with increasingly severe environmental pollution problems, the public has raised awareness of environmental protection and health, hoping to promote a low-carbon lifestyle through their own efforts.
When a series of cutting-edge concepts such as "low-carbon economy" and "low-carbon life" gradually entered the eyes of ordinary people, the term "low-carbon" has become an idea and goal of life and work With the advent of the carbon economy era, low-carbon furniture is also increasingly valued by people. A "low-carbon" wind is quietly entering the furniture industry .
The reporter saw in several furniture hypermarkets in a city that some low-carbon and environmentally friendly furniture attracted many consumers to stop, and the marketing staff was also seriously explaining the relevant knowledge about low-carbon furniture. "Now living standards have improved, and buying furniture also pays more attention to quality and health. Choosing some low-carbon and environmentally friendly furniture can be regarded as a contribution to environmental protection."
A Mr. Mao who bought furniture told a reporter from China Sanjing News. The staff of the store also said that as the May Day holiday goes away, low-carbon homes are expected to usher in a buying peak.
For low-carbon furniture, there is currently no complete and detailed definition. "The so-called low-carbon furniture, furniture materials should be a natural degradation of eco-friendly materials, have no pollution and recycling features to meet consumer brand for safety, health, energy demand.
Use low-carbon furniture to save energy consumption and achieve a low-carbon life goal. "Xiong Xiaokun, a light industry researcher at CIC Consulting, said in an interview with a reporter from China Industry News. However, low-carbon furniture has reached consensus in the industry. The state also encourages furniture companies to develop and promote low-carbon, green, and environmentally friendly innovative products.
Because there is no uniform standard in the low-carbon furniture industry, there are many unscrupulous merchants under the name of "low-carbon" to promote sales and even raise prices, so that consumers can not distinguish whether the product is a truly green and low-carbon product. Therefore, consumers should be cautious when buying low-carbon furniture, and distinguish them by looking at the color, smell and texture of furniture materials.
Relevant departments should also speed up the certification system for low-carbon furniture and standardize the operation process of low-carbon furniture. Xiong Xiaokun said: The industry should accelerate the improvement of certification services, and at the same time formulate detailed standards for the production of low-carbon furniture to transportation, and strict supervision. Only when supervision is in place, certified trademarks can meet the value, so that consumers can clearly consume.
The country is currently calling for low-carbon energy saving in various fields, so some products are protected by national policies or can use state subsidies to upgrade product technology and update equipment. This kind of products will not generate too much additional costs, and the price is relatively more. Be close to the people. Therefore, consumers must not think that a product is low-carbon and environmentally friendly, and its price must be expensive.
Consumers must pay attention to rational consumption when buying, to find out where the value of the purchased product is reflected, where it originates, and whether the usage is true, otherwise it will pay an expensive price and buy back a "pseudo-low-carbon" Products, let unscrupulous businessmen succeed.
Low-carbon furniture is a product of people's increased environmental awareness. Low-carbon products must run through the concept of environmental protection from production to transportation. If only the terminal is to achieve energy-saving and environmentally friendly products, it is only obvious, empty and gimmicky.
At the same time, when using low-carbon materials, low-carbon furniture must be rich in design to meet consumers' personalized product needs. In this way, the demand for the low-carbon furniture market is broader, and consumers can be attracted by the products to enjoy low-carbon life, so that this "low-carbon" wind continues to blow.
The liquid level transmitter can convert the changes of various level parameters into analog signals, and transmit them to the control room remotely for centralized display, alarm or automatic control of secondary instruments or computers. Its good structure and installation method can be applied to the continuous detection of liquid level, material level or material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-clogging, anti-cold junction, and solid powdery and granular materials. , can be widely used in detection and control in various industrial processes.

Classification of liquid level transmitters
1. Single flange liquid level transmitter
Single-flange liquid level transmitters have flat flanges and flange liquid level transmitters with insert barrels, both of which are suitable for single-flange liquid level transmitters that use the gravity of the medium to be measured to measure the height of the liquid level. For medium with high viscosity and easy crystallization, it is generally used in open containers or equipment installations.
2. Double flange liquid level transmitter
The double-flange liquid level transmitter is a Differential Pressure Transmitter, which provides a reliable measurement method to prevent the measured medium from directly contacting the isolation diaphragm of the transmitter. The main features are the need to isolate the high-temperature medium from the transmitter, the measurement medium has a corrosive effect on the sensitive components of the transmitter, the suspension liquid or high-viscosity medium, the measured medium solidifies or crystallizes due to changes in the environment or process temperature, and the measured medium is replaced It needs to be strictly purified to measure the first class. Double flange liquid level transmitter is mainly used in the measurement of liquid level in sealed pressure vessels.
3. Submersible liquid level transmitter
The submersible liquid level transmitter has rod type and arm type. Its principle is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the static pressure into electricity. Signal. After temperature compensation and linear correction, it is converted into 4~20mA current signal output. Due to the characteristics of this transmitter, such as convenient installation, strong adaptability, etc., it can perform high-precision measurement from water, oil to paste with high viscosity, and is not affected by the foaming and accumulation of the measured medium. It is generally used in open Devices for mouthpieces or equipment.
