How does the gas detection and early warning instrument warn?

Gas detection and early warning instrument is a mobile area detection and alarm product. The invention integrates sensing detection technology, wireless information transmission technology, wireless information encryption technology and Internet of Things technology. Apply for 5 patented technologies. It has the advantages of convenient carrying, fast detection speed and high detection accuracy. At the same time, through the cooperation with the receiver, a wireless acousto-optic alarm system based on the concept of wireless Internet of Things can be constructed, covering 500 meters, which can truly realize effective real-time monitoring, find the danger at the first time, and then transmit the alarm information to every on-site operator through wireless alarm technology. It is mainly used in the maintenance, construction, hot work, emergency rescue and other environments of closed spaces in dangerous places.

The gas detection and early warning instrument integrates the following functions: wireless alarm information sending and receiving function, distributed control and networking, and portable explosion protection.

Gas detection: combustible gas, toxic gas, O2, CO2, TVOC, etc. 100 can be detected by using sensors with different principles. Up to four gases can be detected at the same time, such as combustible gas, oxygen, carbon monoxide and H2S. Optional CL2, SO2, HCL and NH3.

Wireless control: This product has wireless alarm function. When the product is placed near a dangerous source, it can be wirelessly linked with nano, nano-4S and nano-G3S within a radius of 200 meters, so as to warn the danger level in real time. For example, if multiple gas detectors are selected, the wireless distance can reach 200 meters.

Pumping monitoring: EP-40 explosion-proof air pump can be selected to realize continuous on-site pumping monitoring (up to 50 meters). Used to monitor confined space, underground, high altitude and other inaccessible areas.

Multi-level alarm: it provides three alarm levels and supports priority setting. For example, a multi-gas detector can simultaneously send out alarm information of multiple gases. ?

This product is a gas detection and early warning instrument with wireless transmission function, which consists of GQB-200A7 series, FSG- 103T, EP-40, nano, nano 4S and nano G3. Has the advantages of both fixed and portable products. Large capacity lithium battery power supply, explosion-proof structure, equipped with explosion-proof button switch, easy to operate. The explosion-proof grade is ExdIIBT6GB/ExdIICT6GB. This product is suitable for Zone 1 and Zone 2 of Class Ⅱ A and B places where combustible gas or steam forms explosive mixture with air at the temperature of T 1 ~ T6. It can be widely used in oil refineries, chemical plants and other places where combustible gas leakage is easy to occur. And conduct long-term uninterrupted monitoring of these places.

Product advantages:

1. The circuit and program adopt the fixed table mode with stable performance and excellent performance, and load the best sensors in the industry. It is superior to all portable devices in accuracy.

2. The supporting acousto-optic alarm sounding part is a patented sounding structure. This product has a good alarm effect when giving an alarm.

3. The battery life is long, and 60 hours of uninterrupted detection can be realized as standard.

4. When giving an alarm, the wireless alarm signal is sent synchronously, which can drive the receiver to give an alarm synchronously.
