Explosion-proof meteorological instruments

1.Product introduction of explosion-proof meteorological instruments

The explosion-proof meteorological instrument realizes multiple meteorological monitoring functions through a highly integrated structure. The explosion-proof meteorological instrument is an explosion-proof instrument that performs 24-hour continuous online monitoring of wind speed, wind direction, temperature, humidity, atmospheric pressure, etc. in chemical plants and other places. Shandong Fengtu Internet of Things Technology Co., Ltd., as an enterprise specializing in the research, development, production and sales of integrated explosion-proof meteorological sensors, has been committed to the promotion and application of miniature weather instruments and meteorological environment solutions. With a complete production chain, a strong technical team and a comprehensive marketing team, the meteorological products we develop and produce such as ultrasonic explosion- proof wind speed and direction meters, explosion-proof five-element micro-meteorometers have been widely used in chemical plants, oil depots, tunnels, mines, etc. fields, customers are all over the country, and have achieved good social and economic benefits.

Compared with traditional explosion-proof meteorological instruments, our products overcome the need for high-precision timers and avoid measurement inaccuracies caused by sensor startup delays, demodulation circuit delays, and temperature changes.

The FT-WFB5 explosion-proof meteorological instrument innovatively integrates wind speed, wind direction, temperature, humidity, and atmospheric pressure through a highly integrated structure, enabling 24-hour continuous online monitoring of outdoor meteorological parameters. The five parameters are transmitted through a digital communication interface. Output to the user once.

2. Features of explosion-proof meteorological instruments

1. The ultrasonic probe is hidden in the top cover to avoid interference from rain and snow accumulation and avoid obstruction by natural wind (utility model patent, patent number ZL 2020 2 3215713.X) ☆

2. The principle is to emit continuous variable frequency ultrasonic signals and detect wind speed and direction by measuring the relative phase (invention patent, patent number ZL 2021 1 0237536.5) ☆

3. Integrated five elements of wind speed, wind direction, temperature, humidity and atmospheric pressure (utility model patent, patent number ZL 2020 2 3215649.5)☆

4. Adopt advanced sensing technology, real-time measurement, no starting wind speed☆

5. Strong anti-interference ability, with watchdog circuit and automatic reset function to ensure stable operation of the system

6. High integration, no moving parts, zero wear and tear

7. Maintenance-free, no on-site calibration required

8. ASA engineering plastics are used for outdoor applications without discoloration all year round.

9. The standard output signal of product design is RS485 communication interface (MODBUS protocol); optional 232, USB, and Ethernet interfaces support real-time reading of data☆

10. Optional wireless transmission module, minimum transmission interval is 1 minute

11. The probe is a snap-on design, which solves the problem of looseness and inaccurateness during transportation and installation☆
