.Classification of gas detectors:
() According to the detected gas, it can be divided into: combustible gas detector (portable combustible gas detector) and toxic gas detector (portable toxic gas detector). This type of gas The detector is small in size, light in weight, fast in response and cost-effective.) ① Combustible gas detectors (referred to as explosion detectors,) are generally based on the catalytic combustion detection principle and can detect a variety of combustible gases or vapors. ② Toxic gas detectors are generally It is an electrochemical detection principle. Depending on the optional sensor, it can detect a variety of toxic gases, such as,,,,,,,,, and other toxic organic compounds
The flammable gas alarm is a gas leak detection and alarm instrument. When flammable or toxic gas leaks in the industrial environment, when the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the flammable gas alarm will send out an alarm signal to remind the work to take safety measures. Gas alarm The fire extinguisher is equivalent to an automatic fire extinguisher, which can drive the exhaust, cut-off, and sprinkler systems to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production. Combustible gas alarms can measure various gas concentrations. It is often used in chemical plants, petroleum, gas stations, steel plants and other places where there are gas leaks.
.Alarm usage:
Combustible gas alarms are mainly used to detect combustible gases in the air, common ones such as hydrogen (), methane (), ethane (), propane (), butane (), ethylene (), propylene (), butene (), acetylene (), propyne (), butyne (), phosphine, etc.
Basic classification
According to the use environment, it can be divided into industrial gas alarms and household gas alarms. According to its own form, it can be divided into fixed combustible gas alarms and portable combustible gas alarms.
The industrial fixed combustible gas alarm consists of an alarm controller and a detector. The controller can be placed in the duty room and mainly controls each monitoring point. The detector is installed in the location where combustible gas is most likely to leak. The core component is the built-in combustible gas sensor, which detects the concentration of gases in the air. The detector converts the gas concentration detected by the sensor into an electrical signal and transmits it to the controller through a cable. The higher the gas concentration, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm point set by the alarm controller, the alarm will sound. alarm signal, and can start solenoid valves, exhaust fans and other external equipment to automatically eliminate hidden dangers.
The portable combustible gas alarm is handheld and can be carried by staff to detect the concentration of combustible gases in different locations. The portable gas detector integrates a controller and a detector, making it compact and flexible. The main difference compared with fixed gas alarms is that portable gas detectors cannot be connected to other equipment.
Household combustible gas alarms can also be called gas alarms. They are mainly used to detect household gas leaks and prevent gas poisoning and gas explosion accidents.
Installation Precautions
() The alarm probe is mainly a detection element that contacts the combustion gas sensor. It is composed of a platinum wire coil covered with alumina and adhesive to form a sphere. Its outer surface is attached with platinum, palladium and other rare materials. Metal. Therefore, care must be taken during installation to avoid breaking the probe.
()The installation height of the alarm should be determined according to the properties of the gas.
() The alarm is a safety instrument with sound and light display functions. It should be installed in a place that is easy for staff to see and hear, so that hidden dangers can be eliminated in time.
() The alarm should not be surrounded by strong electromagnetic fields (such as high-power motors and transformers) that would affect the operation of the instrument.
() The density of the gas to be measured is different, and the installation position of the indoor probe should also be different. When the density of the gas to be measured is less than the density of air, the probe should be installed away from the roof with the direction downward. On the contrary, the probe should be installed away from the ground with the direction upward.
