Gas detector in today’s application
Background:
Both stationary and portable gas detectors play a vital role in protecting the safety of crews and Marine ecosystems. Reliable and robust gas detection methods are essential for effective protection of life at sea – dangerous gases are a common hazard on board ships and present unique challenges for storage and transport at sea. Knowing how your gas detector works helps streamline the decision-making process, which in turn helps you streamline the decision-making process when choosing equipment and technology to ensure the safety of your crew.
Gases pose special and higher risks because of the way they exist. In most cases, only very low concentrations of gases are required to cause significant health hazards or possible combustion or explosion, especially in the confined Spaces of most seagoing vessels. Most gases are invisible — and many more are colorless and odorless. These properties mean that gases carry unique risks that cannot be reduced without the use of expertise – but it is only in the last few years that we have been able to use more sophisticated automated detection methods that calibrate at the touch of a button and provide 360, 24/7 protection against gas leaks.
Gas detection technology has come an incredibly long way since it was first developed in the late 19th century. Before the advent of automated electronic methods, people dealing with potentially dangerous gases relied on a variety of primitive methods to protect themselves from the physical and environmental dangers of gases, including canaries used by miners to indicate the build-up of potentially toxic gases underground. Of course, modern gas detection methods have come a long way since then, incorporating multiple techniques that can accurately and effectively identify dangerous gas levels and save lives
How does a gas detector work?
To answer this question effectively, you first need to know what type of gas detector you are using. Different gas detectors have other operating systems that vary according to the type of gas they are designed to detect. Gas detectors generally fall into three broad categories, which work in slightly different ways:
Electrochemistry: High sensitivity electrochemical gas detector can measure carbon monoxide and other toxic gases. They operate through an inductive electrode in the air, sending an electric current to sound an alarm.
Catalytic beads: Using a coil that has been treated with platinum, this type of gas detector most often identifies combustible gases in the air because the coil oxidizes on contact with the gas, which triggers an alarm. Catalytic gas detectors are very common, especially in the home environment.
Infrared: Advanced infrared technology uses transmitters and receivers to accurately measure gas concentrations in the air. Infrared gas detectors, most commonly used for hydrocarbons and combustible gases, use light transmission to determine the type and concentration of gas present and to alert when high concentrations are present.
All gas detectors have one feature in common. Once they detect a critical level of gas, they use a loud audible alarm, sometimes accompanied by a visual cue such as a flash.
Multi gas sensor module
Multi gas sensor module, strong anti-interference ability, high sensitivity, high resolution, small volume and it is easy to install, no secondary calibration, support secondary development support multi transmit method
Portable Multi gas detector
The multi gas detector supports the detection of combustible gases, toxic and harmful gases. The multi gas detector can monitor 4 toxic combustible gases at the same time, and supports free customization of gas detection parameters 4 and 1, 2 and 1, 3 and 1.Multi gas detector, waterproof, dustproof, accurate detection data, sound and light alarm, long service life. The Multi gas detector can be used in gas leakage, pharmaceutical factories and other scenes.
Gas leakage alarm equipment
The gas leakage alarm controller is mainly used for 485 series sensors, including two specifications of digital tube display and color screen display. The data readings detected by the sensor are summarized and displayed on the display screen. At the same time, according to the setting, when the current data is greater than the alarm concentration, the gas alarm controller will carry out a series of alarm actions, such as sound and light alarm, exhaust power failure, etc. (according to customer settings), The gas alarm controller can support the control system with up to 16 sensor inputs, support two-way relay control, and can linkage exhaust, power failure and other behaviors.
