Explosion Proof Sensor

1.Explosion Proof Sensor Product Introduction

Shandong Fengtu Internet of Things Technology Co., Ltd., as a company specializing in the development, production and sales of integrated explosion-proof meteorological sensors, has been committed to the promotion and application of micro-meteorological 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 instruments, explosion-proof five-element micro-meteorological instruments, have been widely used in chemical plants, oil depots, tunnels, mines and other fields, with customers all over the country, and have achieved good social and economic benefits.

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

Explosion Proof 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 and output the five parameters to the user at one time through the digital communication interface.

2. Explosion Proof Sensor Product Features

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

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

3. Wind speed, wind direction, temperature, humidity and atmospheric pressure 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 stable operation of the system

6. High integration, no moving parts, zero wear

7. Maintenance-free, no need for on-site calibration

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

9. The product design output signal is standardly equipped with RS485 communication interface (MODBUS protocol); 232, USB, Ethernet interface are optional, supporting real-time data reading☆

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

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