Explosion Proof Sensor

1.Introduction to Explosion Proof Sensor Products

Explosion Proof Sensorl is specially designed for explosive environments and is used to monitor wind speed, wind direction, temperature, humidity and atmospheric pressure in relevant areas.Shandong Fengtu IoT Technology Co., Ltd., as an enterprise specializing in the research, development, production and sales of integrated explosion-proof meteorological sensors, has always 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, we developed and produced meteorological products such as ultrasonic explosion-proof wind speed and wind direction instruments, explosion-proof five-element micrometeoroscopes, etc., 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 meteoroscopes, our products overcome the demand for high-precision timers and avoid inaccurate measurement problems caused by sensor startup delay, demodulation circuit delay, and temperature changes.

Explosion Proof Sensor innovatively realizes wind speed, wind direction, temperature, humidity and atmospheric pressure through a high-integration structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters, and output five parameters to users at one time through the digital communication interface.

2.Explosion Proof Sensor product features

1.The hidden ultrasonic probe on the roof cover avoids interference from rain and snow accumulation and avoids natural wind shading (Utility model patent, patent number ZL 2020 2 3215713.X)☆

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

3.Five elements of wind speed, wind direction, temperature, humidity, and atmospheric pressure (utilitary 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, automatic reset function, ensuring stable operation of the system

6.High integration, no moving parts, zero wear

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

8.Use ASA engineering plastics for outdoor applications without changing color all year round

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

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

11.The probe is snap-on, which solves the problem of inaccurate loose transportation and installation process☆
