Explosion-proof weather sensor

1. Explosion-proof weather sensor product introduction

Shandong Fengtu Internet of Things Technology Co., Ltd., as an enterprise specializing in R&D, 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, we have developed and produced ultrasonic explosion-proof anemometers , explosion-proof five-element micro-weather instruments and other meteorological products, which have been widely used in chemical plants, oil depots, tunnels, mines, etc. Fields, customers all over the country, and achieved good social and economic benefits.

Compared with traditional explosion-proof meteorological sensors , our products overcome the need for high-precision timers and avoid inaccurate measurements caused by sensor start-up delays, demodulation circuit delays, and temperature changes.

The FT-WFB5 explosion-proof meteorological sensor innovatively realizes wind speed, wind direction, temperature, humidity and atmospheric pressure through a highly integrated structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters. One-time output to the user.

2. Product features of explosion-proof weather sensor

1. The ultrasonic probe is hidden in the top cover, avoiding the interference of rain and snow accumulation, and avoiding natural wind blocking (utility model patent, patent number ZL 2020 2 3215713.X)☆

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

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

4. Using advanced sensing technology, real-time measurement, no start-up wind speed☆

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

6. High integration, no moving parts, zero wear

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

8. Using ASA engineering plastics for outdoor applications does not change color all year round

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

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

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