How many types of gas detectors are there？
Understanding the common types of gas detectors and exploring why enterprises need to install gas detectors has far-reaching significance for improving the level of production safety management of enterprises.
Production safety is always the focus of the transformation and upgrading of enterprises and factories, with the rapid development of the industrial Internet, digital technology empowered by digital transformation of enterprises to enable enterprises to better monitor and manage the production process, drive the safety and efficiency of enterprises and factories to innovate.
what is a gas detector
Gas detector is a real-time detection of combustible gases or toxic and hazardous gases in the environment leakage concentration of specialized instruments, the core component is the sensor. When the concentration of the gas to be measured in the environment reaches or exceeds the preset alarm value, the gas detector will immediately sound and light alarm, but also can be linked to solenoid valves, fans and other actions to remind people to pay attention to safety and take appropriate first aid measures.
The classification of gas detectors
1.Classification according to the detection principle
Electrochemical type, thermal conductivity, semiconductor type, catalytic combustion and infrared absorption type.
2.Classification by installation
Fixed gas detector, portable gas detector.
Fixed gas detector needs to be installed on the wall or ceiling and other places where the gas is easy to leak, generally need to be perforated installation, the instrument’s installation environment, installation height have strict requirements. Users need to read the product manual carefully or ask a professional to install it.
Portable gas detector is small in size, no need to fix the installation, the staff can carry with them. Applicable to atmospheric monitoring, environmental cleanliness monitoring, landfill monitoring, petrochemical, metallurgy, mining, confined space entry, hazardous substances rapid response, industrial paint, leak detection, indoor air quality IAQ monitoring.
3.Categorized according to the use of the environment
According to the use of the environment can be divided into civil, commercial and industrial use of two kinds.
Civilian gas detector is generally installed in residential homes, detecting natural gas, liquefied petroleum gas, carbon monoxide leakage concentration.
Commercial and industrial gas detector is generally explosion-proof products, applicable to large-scale industrial and commercial, such as petroleum, chemical, metallurgy, scientific research, large supermarkets and other fields.
How to choose the right gas detector enterprise
Installation of gas detectors to help companies find and control the leakage of toxic and hazardous gases in a timely manner, to ensure production safety, in line with national and local safety regulations, and promote green development of enterprises.
In the face of a wide variety of gas detectors with different functions, how to choose the right equipment for the enterprise has become a key issue.
When choosing gas detectors, enterprises need to comprehensively consider the following key factors:
3.1 Clear gas detector detection object
3.1.1 Gas type
To clarify the type of gas that needs to be detected. Different gas sensors are suitable for detecting different types of gases, such as combustible gases and toxic gases. Therefore, when selecting a gas detector, it is necessary to ensure that its sensor can detect the target gas.
3.1.2 Gas concentration range
Understand the concentration range of the target gas in order to select a detector with appropriate detection range and accuracy.
3.2 Environment for using the gas detector
3.2.1 Environmental conditions
Consider the conditions of temperature, humidity, pressure, etc. in the working environment, as well as the presence of corrosive gases, dust and other factors that may cause damage to the detector. Select a gas detector that can adapt to these environmental conditions.
3.2.2 Safety requirements
For high-risk environments such as flammable and explosive, toxic and hazardous, gas detectors with explosion-proof, corrosion-resistant and other characteristics should be selected, and ensure that they comply with relevant safety standards and regulations.
3.3 Focus on detector performance
3.3.1 Gas detector working principle
Different gas detectors use different detection principles, such as electrochemical, catalytic combustion, infrared absorption and so on. Enterprises should choose the most suitable detection principle according to the nature of the gas to be tested.
3.3.2 Detection range and accuracy of gas detectors
The gas detector should be able to accurately detect the concentration range of the target gas and maintain high measurement accuracy within the range. Too wide or too narrow detection range may affect the detection effect. Selecting a gas detector with high precision and good stability can reflect the gas concentration more accurately and avoid misjudgment and missed detection.
3.3.3 Response time
The response time of the gas detector is directly related to the timeliness of its warning. In an emergency, a fast response detector can send out an alarm earlier, and strive for valuable time for evacuation and emergency disposal.
3.3.4 Stability and life
Gas detectors should have good stability and long service life to reduce maintenance costs and replacement frequency.
3.3.5 Environmental adaptability
Different working environments have different requirements for detectors. For example, high temperature, high humidity, corrosive and other harsh environments need to choose a detector with special protective measures.
3.3.6 Intellectualization and linkage
Modern gas detectors often have intelligent features, such as self-calibration, self-diagnosis, remote monitoring and so on. At the same time, they can also be linked with the fire system, ventilation system, etc., to improve the overall emergency response capability.
3.4 Portability and Installation of Gas Detectors
3.4.1 Portability
Portable gas detectors can be chosen if they need to be moved frequently or tested at different locations. These instruments are usually small in size and light in weight, making them easy to carry and operate.
3.4.2 Installation
For detection in fixed locations, fixed gas detectors can be chosen. These detectors are usually installed on walls or ceilings and can monitor the gas concentration in the environment in real time.
3.5 Gas Detector Selection
3.5.1 Detector manufacturers
Technical strength: qualified manufacturers usually have strong technical strength and R & D capabilities, able to produce high-quality high-performance detector.
Product quality: the strength of the manufacturer has a more intelligent workshop and assembly line, better guarantee the quality of the instrument.
After-sales service: gas detector is a precision instrument, the user chooses the strength of the manufacturer, you can enjoy more perfect after-sales service, once the problem occurs, can get timely and professional solution.
3.5.2 Detector qualification
Due to the harsh working environment, the performance, appearance and material of the gas detector are highly required. Users in the selection of instruments, to purchase products with explosion-proof certificate, fire certification, type approval certificate of measuring instruments, appearance patent certificate and other fully qualified products.
3.5.3 Testing instrument brand
Choose a well-known brand, a good reputation for gas detectors, while focusing on after-sales service, in order to get timely technical support and maintenance in the process of use.
More brands of gas detectors on the market, users need to pay attention to product performance parameters and brand reputation, choose the brand with a high reputation.
Gas detector as an important tool to prevent the leakage of toxic and hazardous gases, play an irreplaceable role in safeguarding the safe production of enterprises and employee health.
Through comprehensive consideration of a variety of factors to choose the right gas detector, the enterprise can more effectively prevent safety risks, to ensure the smooth progress of production activities.
