Data Logger

Data Logger - a Wonderful Device

In this era of hard or neck ache competition between different companies increase the pressure over the industry. Everybody wants to be the best in their respective field and to be the best they need accurate results for better analysis of their manufactured products. This gives origin to the need of this device.

What are data loggers?

The term “data” means numerical digits or statistics collected together for analysis and other word “logger” states that it is an device which stores events, observations or measurements in a systematic manner.

These gadgets are the stand alone device means you don't need the help of any external machine to make it work. It stores the collected data in its internal memory. Although Micro sd cards or computer memory are used to increase its storage capacity.

What are the important parameters to choose a perfect data logger?

Most type of them is only designed to take certain or one type of input. So purchase only that type of loggers which have the multiple input options.

It is available in market in both the forms (single and multiple channels type design).It gives the freedom to data recorder to receive hundreds of input. Some of the loggers have 400 channels.

The size of this machine also matters a lot because in many cases the applications have less space and this will create a critical problem. There are many types of logger’s available in market now a day’s with Variety in diverse sizes.

These machines have low data storage capacity due to low sample rate this happens due to the fact that all the data is stored in its internal memory and it is very less. While purchasing data loggers don’t forget to check its sample rate and sample duration first because these are the two key points which can increase the memory power and speed of calculating data in this gadget.

Computer friendly Data Logger have the capacity to show the calculated results on computer.

What are the good points about data loggers?

They are more economical and affordable.

They are more flexible and available in market with various types of input signals.

At a cheap price you can get an additional benefit that is you can connect Data Logger  to your

       personal computers and this can help you in easy transportation of data. Although this feature is

also present in other recorders but you have to pay more money to buy them.

It comes in various sizes and shapes and has high sample rates also.

It can itself collect the data there is no need of external help.

These are the battery powered devices and you can also use external power for help if you want.

This device use non- volatile memory for data storage so it would not delete the data if the battery fails.

It’s a wonderful gadget to use so don’t waste time and buy it as soon as possible.

Humidity Meter

Humidity Meter - Important Industrial Tool

As the world became advance so the technology is. It’s the natural rule of nature that if the moisture content arises in environment humidity also arises and vice versa. You can yourself see the various examples of this rule in your daily life. You can easily find it mostly in those season’s where the level of temperature fall down and the wetness is more in the surrounding environment. 

Therefore, Humidity meter is the important industrial tool to solve various problems related to moisture content in the air.

In which season humidity is more?

In rainy season the temperature is low so the full evaporation of water vapors does not take place. Thus, level of moisture rise in this season. These vapors absorb infra red light and reflects green light that’s why the term “selective absorber” is coined for these water vapors.  This creates the problem of wrapping, cupping, cracking and shrinking in wood products.

What is the device used to measure moisture?

Now we know that why vapors are present in air but how can we measure the correct amount of water in the atmosphere. Here comes, the Humiditymeter it is a device by which you can exactly tell the quantity of moisture in the atmosphere.

What are the different scales to measure Humidity?

There are three different measurements which are used to elucidate dampness and that are described below:

v  Absolute humidity: It shows how much amount of water is present in the air. It is dependent upon two things that are temperature and pressure. If these two things change then the absolute humidity also changes.  

v Relative Humidity:  It functions is to regulate water quantity and temperature level in the atmosphere. It represents the partial ratio of pressure (of water content) in the mixture of air and water in respect to saturated vapor pressure.

v  Specific Humidity: It’s the ratio of water in the dry air in a fastidious mass. It is also said that specific humidity explains the total water content in the whole system including the dry air and water vapor.

What are its uses?

The uses of this meter are explained below:

1.       fermentation chambers

2.        green houses

3.        glove boxes

4.        incubating eggs

5.        data loggers

6.        saunas

7.        These are also used to take care of wooden instruments like guitars, violins so that they cannot get damage by improper level of humidity.

8.       In paint industry, hygrometers are used to maintain the required level of humidity because paint coatings are sensitive to moisture.

9.       In house, this instrument is used to maintain the optimum level of humidity so that it prevents the growth of dust mite.

Due to uprising usage of this Humidity Meter, the demand of this product is raising a lot.
