Under what conditions would it be better to choose a flue gas analyzer
The application of flue gas analyzers in the chemical industry was once very common. As a process control instrument, they provided important data for controlling and guiding the chemical consumption process. This makes process control more timely and precise, achieving consumption optimization and maximizing benefits.
What is the prerequisite for selecting a suitable flue gas analyzer for oneself.
1、 To understand my needs and choose a gas detector, the first thing to understand is what gas to detect? In what environment is it used? Portable or fixed? And other accompanying functions. These reasons are usually something that must be considered. Otherwise, it will present the original
I originally planned to buy an oxygen detector but ended up buying an ozone detector, which caused a big problem. Not only did it delay things, but it also caused unnecessary economic losses.
2、 The common functions of a gas detector are to detect gas concentration, alarm for exceeding standards, and so on. But many customers demand more than just these functions. Signal output is one aspect, which requires current output and digital signal output,
Voltage output and switching output, etc. There may also be some other special requests such as network interfaces and wireless signals. At the same time, data recording and processing are also relatively common requirements.
3、 Understanding the working conditions of the application environment, various gas detectors have strict requirements for the on-site environment. Generally speaking, the temperature is 20-60 ° C, the humidity is 0-95% RH, the pressure is 106Kpa+20Kpa, and so on, including dust and flow rate. Due to the significant impact of other impurities in the environment on the detection results, unforeseen losses are incurred. At the same time, understand the on-site working conditions and provide the manufacturer with this information in a timely manner, and the manufacturer will have corresponding plans to handle it.
4、 Understanding the origin of sensors Many gas detector manufacturers' sensors are nominally foreign sensors, but it is not necessarily the case. Some use domestic sensors to impersonate imported sensors to deceive consumers. When encountering such situations, it is necessary to carefully verify product information and sign purchase and sales contracts if necessary to ensure one's rights and interests.
5、 Under the understanding of the safety conditions and conditions on site, there are mandatory requests for explosion protection and other measures for the use of gas detection devices on site. The coal, petroleum, and chemical industries have very strict requirements for explosion-proof, requiring instruments to have both explosion-proof and explosion-proof certification. Other environments may require gas detectors to have environmental certification or measuring equipment permit documents.
