Wireless Gas Detection and Alarm System
Detection of gas and taking necessary precautions automatically is one of the indispensable needs for all areas where gas is used.
It will ensure that negativities that may occur during the use of gas are detected and prevented in a timely manner
It will ensure that you and your gains are protected.
Gas Alarm Systems
A wireless gas alarm system consists of the following main elements.
1. Wireless Sense Sensor
2. Wireless System Antenna
3. Electronic Evaluation / Indicator / Control Board
3. Audible / Light Warning Devices
4. Automatic Gas Shut-Off Valve
5.Call center -Automatic connection modules for benefit
The points we need to underline in terms of safety among the properties of the gas are as follows;
In case of natural gas and LPG leakage, they are noticed with their artificial / natural odors.
Natural gas is lighter than air. In case of leakage, it rises to the ceiling and is easy to drain.
LPG gases are heavier than air. In case of leakage, it collapses towards the floor and is more difficult to evacuate.
The lower explosion limit of natural gas is 5% volumetric and the leakage concentration reaches 1%
volumetric, in other words, 20% LEL level It is the ALARM threshold accepted worldwide.
For LPG gases, the lower explosion limit is 1.5-2% volumetric and the leakage concentration melts.
The 0.3-0.4% LEL level is the globally accepted ALARM threshold.
Alarm systems need to measure up to 100% LEL level and useful
is not. A measurement between 0% and 20% LEL is sufficient.
Natural gas is safer than LPG in terms of higher lower explosion limit.
LPG, which has a narrower range in terms of explosiveness, is more
is safe.
Wireless system general Features
Two-way radio communication in accordance with the IEEE 802. Pro standard for 15.4 wireless sites and features for ZigBee to be used in the unlicensed 2.4-2.48 GHz frequency range with 100 mW unlicensed power levels;
Although all equipment works with batteries, batteries are long-lasting. The panel and all equipment in the field provide two-way communication online. Apart from the alarm information, information on pollution, battery level, communication status can be followed online.
stability due to high reliability and communication channel:
- Automatic scanning during the upload process and selection of less than 16 busy channels,
- (Quad Offset Phase Keychain Shift) O-QPSK manipulation to expand the spectrum of 2 MHz radio-channel using direct array method and use,
- Radio-traffic acceptance at various levels of a flexible system of radio interference (channel, transport, application) and failure analysis and reaction,
- Providing paths backup options (system control more than 2 routes from each node) to deliver a notification,
- Automatic path selection between all repeater levels (both during setup and in operation);
information dynamic routing, wireless devices "seek themselves" to transmit messages, and the display and display of the control panel can predict quality parameters and status of redundant paths;
Control panel - The system radio network system is the central control unit of all enrolled devices, each other devices do not have a unique connection. Any change in device location geometry is allowed. In this case, ways to transmit information to the control panel are automatically generated;
Maximum ease of system setup and configuration is provided - if needed enough to register and install additional routers between problematic wireless devices. In this case, their routes in the radio network are set automatically;
The radio network registration process is consistent for all devices, except the key fob, and the devices are not dependent on the power process;
