Without Dew Point Accessories, Dew Point Meters are like Engineless Fastest Cars

When we talk about dew, the first thing that comes to our mind is some rose petals dipped in water drops; wet nodes of grass; water dripping from flag leaves of Poaceae or water drops glittering on the tip of efflorescent Zoysia grass flowers. But, an industrial definition for dew is different and a slight negligence in its measurement will directly afflict profits. However, without dew point accessories, a dew point meter is incapable of assuring everything out of danger; it is more likely an engineless fastest car. In this article we will be exploring few of its accessories as follows:

Measuring Chamber:
 
A measuring chamber is perhaps the most important accessory of a dew point sensor because it is not only used for ensuing the maximum flow past the dew point sensor rather it is important for sensor protection and easy association and extrication to compressed air system. Their measuring points may vary and could be anything between 1 l/min at the rate of 0.8Mega Pascal to 2 l/min at the rate of 0.8 Mega Pascal (MPa). There are different models that can be used with compressed air or gas. The most prevalent measuring chambers are as follows:

• Standard measuring chamber: this measuring chamber is suitable only for compressed air up to 16 bar
• High pressure measuring chamber: the next comes in the category is high pressure measuring chamber and these are suitable for any compressed air up to 350 bar
• Measuring Chambers for Granulate Dryer: for this purpose one need a measuring chamber that can handle up to 250 m bar.

Test Pot:
 
When it is about dew point system, it is all about maintaining the right level of humidity and for this reason these test pots are used, another important accessory among the available dew point accessories. A test pot assures a consistent relative humidity of a certain point say 11.3%, which is important for letting the production process run smooth and hassle free. This prefixed temperature (11.3%) is fixed on the basis ambient temperature.

Software:
 
It is not easy to understand each and every piece of associated information and keeping every instruction in your brain’s hard disk is not at all an easy task. Therefore, we need a software utility, a program mastered by some experts to make our measurement easier. There are some software utilities available that can used through a computer connected via USB adapters and interface adapters. These adapters once directly connected with sensors; send direct information and data in a user customized manner.

Therefore, before choosing a seller for dew point sensors, one must take care about the seller competency with dew point accessories. For more info visit : http://www.csinstrument.com

A Guide on Selecting the Right Dew Point Sensors for Smooth Compressed Air Applications

Dew point sensors are instruments that are particularly designed to measure the temperature at which dew develops. Selecting the right dew point meter type in order to meet the stringent requirements of your unique installation is a crucial task. In this article, we will guide you via the most vital questions you must answer when weighing your choices.

The first and foremost question to ask is whether you are browsing for a portable or a fixed dew point meter. Fixed mount sensors generally entail an external power source to function and can range in intricacy from a basic analogue sole device to extremely sophisticated units with data-logging, displays, Ethernet connections, alarm relays and more.

Here are a set of questions that will help you narrow down products to select from-

What do you require the devices to do?
Integrated display or panel meter?
Datalog?
Send a signal somewhere for control or miscellaneous purposes?
Alarm at a low/elevated point?
Fixed mount dew point meters can be set up on the supply-side OEM applications, for dryer monitoring and demand side for end user applications connecting to panel meter displays, PLCs and data loggers.

Dryer Type:
 
In most of the compressed air systems, the kind of dryer will regulate the dew point operating range entailed from the dew point meter type. Presently, there is no single device available in the market that measures all dew point levels accurately. Sensing techniques are optimized in order to excel in certain ranges- moderate-range ambient levels, high humidity condensing atmospheres and extremely dry conditions. Measuring dew point in each of these conditions exhibits it own unique set of challenges.

Selecting the instrument with an accurate measurement range would affect both the long-term and short-term stability and accuracy of the dew point measurement.

Refrigerant Dryers:
 
In systems functioning at higher levels, refrigerant dryers produce dew points between 35-40F. For such measurements, dew point sensors optimized for higher dew points are recommended. Since usage conditions like temperature and pressure can affect the choice of sensor, it is an ideal idea to consult a specialist dealer before making your final decision.

Moreover, it is important to know the temperature and pressure at the measurement site. While the temperature of the compressed air would not have any sort of affect on the dew point value, it might negatively influence the performance of the dew point meter. Prudent management and monitoring of pressure is imperative to making an accurate measurement.

Desiccant Dryers:
 
Compressed air mechanisms utilizing a desiccant-kind dryer can have dew points anywhere between -148 to 22F. Nevertheless, most function between -76 to 40F. It is essential to identify what range you want to control. In case your dryer outputs air at -112F dew points, however, your intended control set point is at -58F, this is where your performance and precision is important.

Contamination Resistance:
 
Finally, excellent dew point sensors have specific features that make sure a dry and clean compressed air system. These include swift wet to dry response time; long calibration intervals; thorough recovery from saturated conditions; high resistance to contamination-immunity to compressor lubricants and chemicals.
