Integrated explosion-proof meteorological sensor

Integrated explosion-proof meteorological sensorWidely used in flammable and explosive environments such as chemical parks, oil depots, tunnels, and mines. By monitoring real-time changes in meteorological parameters, it can help prevent the impact of meteorological emergencies on production and personnel safety, provide important data support for production management, and assist decision-makers in making scientific production plans and arrangements.

1、 Product Introduction

Our company specializes in research and development, production, and salesIntegrated explosion-proof meteorological sensorThe company has been committed to promoting the application of micro meteorological instruments and meteorological environment solutions. With a complete production chain, a strong technical team, and a comprehensive marketing team, we have developed and produced meteorological products such as ultrasonic explosion-proof anemometers and explosion-proof five element micro meteorological instruments, which have been widely used in chemical plants, oil depots, tunnels, mines, and other fields. Our customers are spread 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 measurement inaccuracies caused by sensor startup delays, demodulation circuit delays, and temperature changes.

The WFB5 explosion-proof five element micro meteorological instrument innovatively achieves 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. The five parameters are output to the user at once through a digital communication interface.
