Explosion-proof integrated meteorological instruments, special-purpose meteorological sensors

Explosion-proof integrated meteorological instrument, is a meteorological sensor with explosion-proof function. The design of integrating wind speed, wind direction, temperature, humidity and barometric pressure in one unit realises the simultaneous monitoring of the five elements. 24-hour continuous monitoring and one-time data transmission to the user through a digital communication interface. The product adopts a hidden ultrasonic probe design, effectively preventing the interference of rain and snow accumulation and natural wind, and at the same time, it uses the ultrasonic signals emitted with continuously changing frequencies to determine the wind speed and direction by calculating the phase difference, realising the instant measurement without the need of wind speed activation.

The product features strong anti-interference performance, a built-in watchdog circuit and an automatic reset mechanism to ensure stable system operation. The compact design with no moving parts reduces the need for maintenance, and the ASA engineering plastic material ensures stability and durability for long-term outdoor applications. Standard configuration is RS485 communication interface, support MODBUS protocol, and can provide a variety of communication interface options such as 232, USB, Ethernet, etc., which is convenient for real-time data acquisition. Optional wireless transmission function is available to realise data transmission at least once per minute. The snap-on design of the probe effectively solves the problem of possible loosening during transport and installation.

In terms of technical specifications, wind speed 0 ~ 60m / s (± 0.1m / s) resolution of 0.01m / s, wind direction 0 ~ 360 ° (± 2 °); resolution: 1 °; air temperature -40-60 ° C (± 0.3 ° C), the resolution of 0.01 ° C; air humidity 0-100% RH (± 3% RH), the resolution of 0.1% RH; the atmospheric pressure of 300 - 1100hpa (± 0.3% RH), the resolution of 0.1 % RH; atmospheric pressure of 300 - 1100hpa (± 0.1 % RH), the resolution of 0.1 % RH. 1100hpa (±0.25%), resolution 0.1hpa.

The company has passed ISO quality management system, environmental management system and occupational health and safety management system certification, holds a computer software registration certificate, has been awarded 3A grade credit enterprise, and has obtained Ex ia IIC T4 Ga high-grade explosion-proof certification. The company not only has a complete production line, but also equipped with a skilled R&D team and a sales team with wide coverage. Its products, including ultrasonic explosion-proof wind speed and direction meter and five-element micro-meteorological instrument, have been widely used in many high-risk environments, such as chemical industry, petroleum storage, tunnel construction and mining operation, and have won wide market recognition and customer praise.
