Which brand of dust sensor is more affordable?

The dust concentration detector is mainly used to detect the dust concentration of the instrumentAccording to the different particle size of dust, it can be divided into detection, PM10 detection and TSP total dust detection；According to the requirements of the detection occasion, it can be divided into portable dust meter, explosion-proof dust meter and fixed installation dust meter. In construction sites and other construction fields, there are a lot of dust that looks very small, and although it does not look too dangerous, it cannot be ignored in some situationsFor example, in a confined environment, if the concentration of dust reaches the specified limit, it may cause immeasurable consequences to our economic security and life and health。Therefore, it is very important to use a dust concentration detector in the specified occasions.

In accordance with the requirements of the Ministry of Environmental Protection, the operation sites under the highest conditions, such as some metal production and processing, grain production and processing, feed production and processing, agricultural and sideline products, forest products, synthetic materials, pulverized coal and other places, need to use explosion-proof dust meters, which are divided into portable explosion-proof dust meters and fixed explosion-proof dust concentration alarms; There are also some pipeline flue environment detection, which can be divided into fixed dust concentration sensor and portable dust concentration detector;

The measurement principle of the capacitance method is simple, but the linear relationship between the measured capacitance and the concentration is not one-to-one, and the measured value of the capacitance is easily affected by the change of phase distribution and flow pattern, resulting in a large measurement error. Although the B-ray method is accurate, it needs to compare and measure the dust after sampling, and it is difficult to realize the best monitoring of dust concentration; The measurement of dust concentration by ultrasonic method and microwave method is still in the experimental research stage, and there are few molded products on the market. In the market, light scattering method, light absorption method, and triboelectric method are mainly used to monitor dust concentration, and there are many products formed, which are successfully used in dust concentration measurement and dust concentration measurement in coal mines.

Now there are all kinds of dust concentration detectors on the market, and we must screen whether it is what we need when we buy。The working principle of dust detector is mainly light absorption, light scattering, ray and AC electrostatic induction. At present, the dust monitoring methods mainly include filter weighing method, X-ray diffraction method, scattered light method, piezoelectric balance method, ray dust measurement method and light transmission method.

Gravimetric methods, the most common method of dust measurement, require an electronic balance ranging from 1/10,000 to 1/100,000.

Hello, I am glad to serve you and give you the following answers: There are many brands in the dust alarm market, such as Honeywell in the United States, E+H in Germany, Endress+Hauser in Switzerland, Rosemount in the United States, Emerson in the United States, etc., which are all well-known brands, with reliable quality and stable performance, which can meet different application needs. The cause of the problem of the dust alarm may be due to excessive dust concentration, or due to the failure of the alarm itself, or due to improper setting of the alarm, etc.

Workaround and practice steps:1First of all, check whether the dust concentration exceeds the standard, and if it exceeds the standard, measures should be taken to reduce the dust concentration; 2.

Check whether the alarm itself is faulty, and if so, it should be repaired or replaced in time; 3.Check whether the setting of the alarm is correct, if not, it should be adjusted in time; 4.If none of the above measures can solve the problem, you can consider replacing the alarm.

Personal Tips: Oak Friend 1When using the dust alarm, the dust concentration should be checked regularly to ensure the safety of the stove environment; 2.

Regularly check the alarm itself, hidden as a mold to ensure the normal operation of the alarm; 3.Regularly check the setting of the alarm to ensure that the alarm is set correctly; 4.If the alarm is found to be faulty, it should be repaired or replaced in time to ensure the normal operation of the alarm.

Loefmeer dust sensor is divided into infrared dust sensor and laser dust sensor, infrared dust sensor has HPD05 and GDS06 two models, laser dust sensor has LD07, LD09, LD11, LD13, etc., can be installed in vacuum cleaners, sweeping robots, fresh air systems and other dust detection equipment. The measurement principle of the two types of sensors is different, and there are also differences in the measurement accuracy, size, and interface, which can be learned more on the official website.

How many people are willing to share it if they are really cost-effective, what they can see are people who come out to advertise, good products are cost-effective and high, people don't worry about selling, stuffy heads are making money, can you search like this to find good products? Hell, it's better to explore it slowly, you will know whose house is good if you use it more, and you will brag about your own home before you buy it, and how big the shipment is.

Dust concentration sensors, that is, sensor products used for the monitoring of powdery materials, the total amount of process transportation, the emission monitoring of various fuel boilers and other productive soots, include infrared and laser: infrared dust sensors (including Shenrong, GE, Sharp and other brands) and laser dust sensors (including Shenzhen Senavi, Nuofang Electronics, Sifang Optoelectronics, Panteng Technology and other brands), the two are very different.

First of all, the laser sensor is higher than the infrared generally. Then from the structure, the laser dust sensor has a complex structure, the light source is a laser diode, the air flow in and out is generally specially designed, the sampling air is pushed by a fan or blower, and the output is generally a serial output, like SDS011 and PWM output to save serial port resources of the host computer. Infrared, on the other hand, is relatively simple.

Functionally, the detection data of the laser dust sensor is very close to that of professional instruments, and the credibility of the data is relatively high, while the data performance of the traditional infrared dust sensor is far behind.
