Why is a gas detector necessary?
In the industrial production process, the leakage of flammable, toxic and harmful gases often occurs, which will cause serious threats to personnel, equipment, production, and life. The main reasons for leakage are :1. Material defects of production equipment or containers. 2. The sealing ring and ring are not tightly sealed. 3. The welding place of the container is subject to long-term electrochemical corrosion. 4. Human negligence, etc.
The leaked flammable gas or toxic gas is quickly diluted by air, so the location of the leak is difficult to find, and it is even more difficult to quantitatively analyze it. After a period of time, these gases will accumulate in some areas or at certain blind spots. When the content of flammable gas in the air reaches a certain value, it is very easy to burn or explode when encountering an open flame. If this very dangerous hidden danger cannot be discovered in time, it will cause great loss to personal safety and property.We can use JXCT gas detector for online monitoring, reliable quality, to provide protection for people’s life and health…
How to choose the right gas detector?
1. Wall mount gas detector
This wall-mounted gas sensor is the cheapest industrial-grade gas detector. The overall appearance is made of waterproof ABS plastic, so it can be widely used in harsh environments with more smoke and dust. This gas detector has two output modes: rs485 and analog output, which can ensure stable signal and accurate measurement even after long-term work. The gas detector is equipped with a waterproof temperature and humidity probe at the bottom, which can meet the needs of users to simultaneously detect the three elements of temperature, humidity, and gas. In addition, multiple wall-mounted gas sensors can be installed in an industrial park and the detection information can be uploaded to a unified free cloud platform, effectively realizing accurate measurement and centralized monitoring of multiple locations. This is also the most economical gas detector.
2. Duct type gas detector
This duct mount gas detector adopts a new type of infrared verification technology for gas concentration measurement, and the response is rapid and sensitive, which avoids the short life and long-term drift problems of traditional electrochemical sensors. The enclosure has a high degree of protection and can adapt to various harsh conditions on-site. The measuring element is located in a 22 cm long stainless steel probe. When measuring, make a suitable hole in the tube to be measured, insert the probe and fix it with a flange. After the wiring is completed, the gas concentration in the pipeline can be stably detected for a long time, and the probe is waterproof and has a long service life.
3. Four gas detector
This handheld gas detector is the most popular multi-gas detector on the market. It can simultaneously detect four gases: oxygen, combustible gas, carbon monoxide, and hydrogen sulfide. The detected gas is a common industry gas, so it is widely used. It has a very exquisite appearance, adopts a high-definition color screen design, and is equipped with a suitcase, so it is very professional when going out. This 4 in 1 gas detector is powered by a rechargeable lithium battery, which can be used normally after turning it on, avoiding wiring problems. It has three alarm functions: sound, light, and vibration. It also has a data storage function and can store up to 130,000 items at a time. The user can export or view historical data through the configuration software. Because this gas detection is small in size, it is suitable for customers who can carry it with them for gas detection in different locations.
4. Fixed gas detector
This is a typical explosion-proof gas detector, which is mostly used for the monitoring of flammable and explosive gases in industrial sites. The overall appearance is made of stainless steel, with a high explosion-proof grade, and is certified by the National Institute of Metrology. This fixed gas detector detects a single gas, but the measurable gas range is wide, and there are multiple ranges to choose from, which can greatly meet the needs of most users. When in use, the gas concentration can be monitored continuously for a long time. Once the gas concentration exceeds the standard, it will send out a double sound and light alarm to remind the user to take measures. In addition, this gas detector adopts remote infrared remote control technology, which can modify parameters without disassembly, which is more convenient and efficient.
What should be paid attention to when installing a gas leak detector?
1. Installation location selection
We need to know the distribution of on-site working conditions and where the gas is generated, such as pipe joints, valves, raw material locations, and airflow direction. These are things that we need to consider carefully. It doesn’t mean that you just need to find a place to install it. If it is installed in the wrong place, the gas detector will not be effective.
2. Installation environmental conditions
Gas detectors all have their own suitable working conditions, and they mainly need to pay attention to the basic conditions of humidity, temperature, and pressure. In the general factory environment, it can be directly installed and fixed, but when we install it in a confined space, such as a pipe, a flue, and other special environments, we must strictly control the working conditions. The conditions that most gas detectors can adapt to are: temperature: -20 to 50 degrees, humidity below 90% without condensation, and pressure within the range of 100kp. Once the environmental conditions are not met, it will affect the accuracy of the measurement and the service life of the instrument. At this time, we have to consider adding gas pretreatment equipment to carry out gas treatment, so that the gas that meets the conditions can enter the gas sensor head.
If the dust in the gas is too large, it will also cause the gas sensor of the gas sensor to adsorb and block, and the detection accuracy will decrease. Therefore, once it is used in a high dust environment, the dust must be filtered, and the dust must be cleaned regularly according to the situation. Please remember not to wash with water or use alcohol or other solvents to wipe, only use a clean soft cloth to clean the surface of the detector.
