Introduction to online monitoring of flying dust and noise@fengtu technology

Introduction of on-line monitoring of flying dust and noise@fengtu technology [FT-ZY1] Danasîna çavdêriya serhêl a toz û dengê firînê The on-line monitoring system of flying dust and noise adopts a light-scattering fast dust detector with laser as the light sourc.
The measurement principle is: When light is irradiated on the suspended particles in the air, scattered light is generate.
Under the condition of certain properties of the particles, the scattered light intensity of the particles is proportional to its mass concentratio.
By measuring the scattered light intensity and applying the mass concentration K value, the particles are obtaine.
mass concentratio.

The traditional three-wind cup wind speed sensor structure is adopte.
The wind cup is made of ABS material, which has high strengt.
At the same time, it cooperates with the internal smooth bearing system to start well and ensure the accuracy of information collectio.
The built-in signal processing unit of the cup body can output the corresponding wind speed signal according to the user's needs, which can be widely used in the fields of meteorology, ocean, environment, airport, port, laboratory, industry, agriculture and transportatio.
2 Technical parameters Measurement range: 0-34m/s Accuracy: ±3m/s Starting wind speed: 2-4 m/s Supply voltage: 7-24v DC Output signal: 4-20mA Wind speed value = (output voltage -4) /6*343 Dimensions and installation instructions 4 The fixing method adopts the flange installation method, the threaded flange connection makes the lower pipe fittings of the wind speed sensor firmly fixed on the flange plate, the chassis is Φ70mm, and four are opened on the circumference of Φ61mm The mounting holes are all Φ5mm, and the bolts are used to fix it tightly on the bracket, so that the whole set of instruments can be kept at the best level, and the accuracy of the wind speed data can be ensure.
The flange connection is easy to use and can withstand greater pressur.
Wind direction sensor 1 Features The wind direction sensor is a professional meteorological instrument used to measure the horizontal wind direction of the win.
The Hall angle sensor is used inside, and the low inertia light metal weather vane is used to respond to the wind directio.
When the wind direction changes, the rotation of the rear wing drives the shaft core magnet to rotate through the shaft, so as to output the changed voltage signa.
It can measure the natural wind direction of 0-360 degrees starting from the north of the labe.
It has a high cost performance and can be widely used in the fields of meteorology, ocean, environment, airport, port, laboratory, industry, agriculture and transportatio.
2 Technical parameters Measurement range: 0-360 degrees: (4V, or 4MA corresponds to 0 degrees, the direction of the north) Accuracy: ±1° Starting wind speed: 3m/s Supply voltage: 7-24v DC output signal: 4-20mA Wind direction value=(output voltage-4)/6*3603 Outline structure 4 The fixing method adopts the flange installation method, and the threaded flange connection makes the lower pipe fittings of the wind direction sensor firmly fixed on the flange, the chassis is Φ70mm, on the circumference of Φ61mm Open four mounting holes with an average diameter of 5mm, and use bolts to fix them tightly on the bracket to keep the whole set of instruments at the best level, to ensure the accuracy of the wind direction data, and the flange connection is easy to use and can withstand greater pressur.
