Increasingly businesses and individuals are investing large amounts in renewable energy power sources like solar and wind energy. Typically the investment required for installing equipment for generating renewable energy is high. Hence it is necessary to find out the exact weather conditions in the place where the solar panel will be installed. Though meteorological solar data is available for most areas, this is data is for large areas, the solar energy received at a particular location where the solar panel is being installed may differ. Hence it is advisable to install a solar weather station before finalizing the location of the solar panel.

The solar energy received at a particular location depends on the solar irradiance at the place and also the number of sunlight hours. Users should be aware that the sensors for measure solar irradiance and number of sunlight hours are different in design and make. While there are a large number of weather stations, only a few weather stations like Davis Vantage Pro two (VP2 ) have a provision for connecting the solar sensors. For each of the sensors the user can choose from the different options available depending on the accuracy, budget and other details

The Davis 6450 solar sensor for sunlight strength measures the global solar irradiance levels , the strength of the sun’s output power in watts per square meter. It monitors the strength or power of the sunshine in a particular area, especially for light in the visible spectrum range. It should be noted that the sensor does not measure the number of hours of bright sunlight received. The sensor can be used directly with the Davis Vantage Pro weather station. The the station can be ordered with the solar sensor in the VP2 Plus models and it is cheaper to do so if the UV sensor is also required, compared to ordering the solar,UV sensor separately.

The solar sensor is compact and can be easily fitted on the weather station. The sensor is mounted on a small shelf next to the rain gauge. In the VP plus model, the solar sensor along with its mounting shelf is pre-assembled. The solar sensor can be installed with the integrated sensor station, it is not necessary to have a station installed. There is a provision for wireless and cable connectivity of the sensor to the main console. In addition to solar power generation, the solar sensor is also used for agricultural applications where the farmer has to measure the sunlight received.

In addition to the sunlight strength, it is also necessary to measure the duration for which bright sunlight is received accurately. For this the Intromet Sunshine Hours sensor is connected to the Davis weather station. This sensor can be used as a standalone unit if required. The sensor has a sensing element located within a glass dome, and the light intensity depends on the shadow which is cast. On cloudy days, no shadow is visible while during bright sunlight, a strong shadow is cast which is detected and recorded. This method of measuring sunlight hours is widely used in solar weather stations.

A digital anemometer helps to change the way in which we calculate the speed of wind very fast. It helps us to comprehend the behavior of the wind and it is used by several sectors right now. The anemometer has many more uses than before when it was first employed by the weather stations. Let us take a look at the different applications of the device.

The term anemometer was first derived from the Greek word “anemos” which implies wind. At present these gadgets have become digital and they operate on the basis of small computers and detailed electric circuits that are able to compute the velocity plus the pressure of the wind precisely.

At present, we use a digital anemometer for various purposes like power and electricity generation, the sea fishing industry, exhaust convulsions, steel industry, and so forth. Besides these, we also use them for outdoor pursuits like hiking, trekking, camping, and so on. The device can be much more effective if it is equipped with other useful features like a wind pressure measurement device and a temperature tester. A digital pressure gauge will also enable you to calculate wind pressure accurately, thus aiding you to plan your outdoor activities in an organized manner.

Nevertheless, you may also take some precautions while using a digital anemometer out there. Below, we have mentioned some of the major precautions that you ought to take while using the device.

1. Always make it a point to use an anemometer that operates on a digital platform and, for this, you ought to stick to the instructions provided by the manufacturer. If you don’t pay heed to the instructions, there is always the possibility of a minor shock or fire.

2. Never use the gadget in the rain since it will get damaged in that case. The reason for this is that most of the anemometers out there are not water-resistant whatsoever. For this, you need to look at the instructions provided to you by the vendor while you got hold of the product. This will help you to prevent the device from getting damaged in the long run. Moreover, your property will not suffer any kind of damage too.

3. Make it a point not to open the casing of the sensor area by any means (it should only be opened by an experienced and well-trained expert). You must also never touch the sensor area for your personal safety. This will also prevent the anemometer from getting impaired.

4. Remove the battery and store it in a safe place if you are not going to use the device in the near future. There is a possibility for the battery to suffer from leakage if it is not used for a long period of time, and this might damage the wind projector too.

5. Never bring the anemometer in contact with the direct sunlight, dust, high humidity, etc. Also, don’t use any strong chemicals to clean the stuff. all of these factors could damage the digital anemometer permanently or they might undermine the overall performance of the gadget.

Though both methods, engraving and etching, can be used for cutting hard surface like metal precisely still they have a few primary differences. One of the main primary differences between engraving and etching is that etching is a chemical process whereas engraving is a physical process. Sharp tools are used while engraving lines into a hard surface whereas the lines are burnt by using a kind of acid while etching the surface. The information provided here under can help you in understanding etching engraving difference more precisely.

Engraving

Engraving is a method to decorate a metal sheet with images and text by hand with the help of certain sharp tools. Most of the ancient art pieces like guns, silverware, jewelry, and other items have been engraved by the engravers to make them look more attractive and beautiful. Until early 17th century engraving was the dominating method of printing artistic thing but after that etching surpassed it due to its low cost and less effort required for it as a lot of skills and efforts were required to cut a metal by physically. With the increasing popularity of etching many artisans switched from engraving to it. But engraved prints remained popular as a commercial method of reproducing images until the introduction of photography.

Etching

Etching is the simplest process to create some design on metal sheets as the artist has to cover the sheet with a layer of wax or some other mask material and scratch the desired design with an etching tool on the mask. After finishing the design he has to dip the metal sheet into a container containing acid to dissolve the exposed part of the sheet. The basic principle of the process of etching different type of materials can be the same though the mask materials can be different. For instance if you have to etch glass sheet then you will have to use a hydrofluoric acid solution to reveal the design created by using a acid-resistant material on the glass.

Engraving vs etching

In printing

Both, engraving and etching, are the types of intaglio printing in which lines are cut into a flat facet. Though they produce lines by using different methods but the process of printing them is similar. When an etched or engraved plate is inked and wiped then ink will remain only in the engraved or etched lines which can help in transferring the inked image to a sheet of paper. This print can be darker if the lines are deeper. But these images will be drawn in reverse as the print will be in reverse in both cases.

In quality of lines

The quality of lines created by engraving a design will be much better than any other printing method as the lines created by the engraver are very sharp and crisp. This feature makes engraving an ideal method for printing fine items like currency. The lines created by etching are a bit fuzzy as acid can create rougher and wider lines than created by the etching artist by burning the metal under the wax.

Thus, you can easily understand etching engraving difference with the help of the facts discussed in this write-up.
