Automatic weather stations are an important part of China's ground-based observing systems. The detection level and operational capability of automatic weather stations have increasingly become an important factor affecting the basic operational capabilities of meteorological services and the level of meteorological services in China. To improve the accuracy of weather forecasting and the quality of meteorological services, it is imperative to reduce the error rate of observation data and improve the operational capability of equipment. Due to various factors such as the detection environment and the inherent instability or malfunction of the automatic weather station equipment, unverified raw observation data may have non-true or false values. In order to prevent and eliminate the adverse effects and consequences caused by erroneous observation data for decision-making services, professional services and public services, and ensure the accuracy, reliability, and comparability of observational data of meteorological elements, the quality control of observation data is very important. of. Hand-held weather stations are convenient weather monitoring instruments.

The error in the observation element data and the error in the format of the hand-held weather station are the main factors leading to the low availability of observation data at the automatic weather station. From the classification of causes of failure, it can be seen that lightning strikes accounted for 47% of the total number of failures, which is the main reason for the failure of automatic weather stations. Moreover, the damage of lightning strikes is large. A lightning strike process can often cause destruction of automatic weather station equipment. Strikes, resulting in a number of times when the data has not been reported, the file format is incorrect, and the observed element data is incorrect. Therefore, strengthening lightning protection measures at automatic weather stations and reducing lightning accidents are important steps in improving the operational capabilities of automatic weather stations.

In the absence of AC power, the battery of the observation station's automatic station equipment can maintain the collector for hours of work. When the network is interrupted or the power supply is temporarily interrupted, the station personnel will interrupt the network immediately after the network and power supply return to normal. The observing data download pass. The difference in hand-held weather stations is that they are easy to carry and do not have a similar situation.

Queench And Tempered Steel Plate

Besides Heat Treated Wear Plates (AR Plate or Q&T Steel), HP Wear Resistant Group offers various wear resistant steel products including Cr-Carbide Weld Clad Plates, Smooth Surface CCO plate, Casting Plates, Tungsten Carbide Coated Plates in various grade and multiple size options.

quenched and tempered Steel Plate is available in thicknesses from 1/8" to 4", it can be cut by gas, abrasive water jet, laser, or plasma.

An abrasion resistant, quenched and tempered, high strength, fine grained steel Wear Plate and Abrasion Resistant Wear Plate offers low cost wear protection. With a hardness of 250 to 320 BHN, it will outlast hot rolled carbon plate but can still be drilled, punched, or machined for liners and wear plates. Strength characteristics of this plate make it an excellent choice for structural use.
