可以有效的检测出可燃有毒性气体的浓度，预防气体泄漏后可燃有毒性气体浓度超标。 The fixed ethane gas leakage alarm can effectively detect the concentration of flammable and toxic gas, preventing the concentration of flammable and toxic gas from exceeding the standard after gas leakage. The machine is composed of a gas alarm controller and a gas detector. The controller can be placed in the duty room and mainly controls the monitoring points. The combustible and toxic gas detector is installed at the place where the gas is most likely to leak. The core component is a built-in gas sensor, and the combustible gas sensor detects the concentration of combustible gas in the air. The gas detector converts the combustible gas concentration detected by the sensor into an electrical signal and transmits it to the controller through the cable. The higher the concentration of the flammable toxic gas, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm set by the gas alarm controller At that time, the gas alarm controller issues an alarm signal and can activate externally connected equipment such as solenoid valves and exhaust fans to automatically eliminate hidden dangers.
The alarm produced by Jinan Anruide Electronics Co., Ltd. has obtained the fire protection product type approval certificate issued by the National Fire Protection Electronic Product Testing Center, and has a production permit for measuring instruments issued by the National Quality and Technical Supervision Department.
The gas alarm used in the industrial industry is very frequent. The gas alarm can be used to monitor the concentration of flammable, toxic and harmful gases in the air in real time. When the gas concentration reaches the set value range, the alarm will sound in the form of sound and light. What precautions are needed to install gas alarms and troubleshooting?
Matters needing attention for safety gas alarm
Industrial installation of explosion-proof gas alarms needs to be in the fire monitoring duty room (non-explosion-proof area), and the location and height of the device should be in a place that is easy to install and maintain.
The gas detector should be installed at the location where the detected gas is most likely to leak or accumulate. If the detector is used for area protection, the detector needs to be installed at a location that can reflect the average concentration of the current area. Generally, the gas detector is installed at a position that can represent the average concentration in this area.
The number of detectors required in an area depends on several factors: the structure of the building, the way the air flows, the type of gas being monitored, and the degree of protection required.
The detector should be installed facing down. Never point the sensor towards the sky or ceiling. Do not intrude the detector into water or other liquids.
How much is a fixed ethane gas leak alarm ?
Many users often ask "How much is a flammable gas detector?" But our customer service specialists cannot directly quote. Let's explain to the users today, why can't we quote you first?
First, there are many types of combustible gas detectors. For example, combustible gases include methane, propane, methanol, paint, toluene and other gases. The specific price of combustible gas detectors that detect each gas is different, so we cannot give them immediately. You quote.
Secondly, we need to know the number of combustible gas detectors purchased by the user in order to make a specific offer, because the more the number, the more appropriate the price. There is a price difference between buying one and buying one hundred, I believe many people can understand.
In the end, we should be based on the principle of being responsible for the user. We will first inform the user of the company's product information, company product qualification certificate, and company after-sales situation, so that the user first understands the product. At present, some companies on the market use low-quality and low-quality products to disrupt the market. There is no after-sales service and their qualifications are incomplete.

The controller needs to be wall-mounted on the wall of the duty room or monitoring room, which can be about 160CM away from the ground. The combustible gas alarm in the chemical factory warehouse and the intelligent monitoring detector can be installed by holding the pipe, wall or bracket. the way. The specific installation position of the detector is determined by the specific gravity of the gas. The specific installation plan is as follows:
1. When the specific gravity of the detected gas is greater than the specific gravity of the air, the gas detector should be installed at a distance of 30 to 60 cm from the ground with the sensor part facing downwards.
2. When the specific gravity of the detected gas is less than the specific gravity of the air, the gas detector should be installed at a distance of 30 to 60 cm from the ceiling with the sensor part facing downward.
The installation position of the probe is determined in accordance with the relevant provisions of GB50493-2009 "Design Specification for Detection and Alarm of Combustible Gas in Petrochemical Industry" based on the density of the detected gas and the wind direction. The installation position of the detector should be avoided to prevent air flow from the detector.
In general, the area is suitable for indoor space. The points are evenly distributed according to the protection radius, that is, the detector is installed within 7.5m from the release source or within 15m of the horizontal distance between the two detectors. The distance between the full-frequency wind direction wind side of the gas source and the release source should be 15m; the distance between the full-frequency wind direction wind side of the gas source and the release source should be 5m.
The installation height of the detector for detecting heavier than air should be 0.3 ～ 0.6m from the surface; the installation height of detector for detecting lighter than air should be 0.5 ～ 2m.
Note: The gas density is considered to be heavier than air when it is 0.97kg / m3 (standard state). The gas density is considered to be lighter than air when it is 0.97kg / m3 (standard state).
