Dew Point Meter
The Dew point meter can be perceived as the temperature at which the water vapor content in a gas arrives at a soaked state. It is one of the approaches to communicate the outright stickiness of a gas. It may very well be seen that the dew point temperature is a unit system for measuring the moisture content of a gas. The dew point meter is an instrument that measures the absolute moisture content of gas dependent on this unit system.
An Embedded microcontroller-based precision instrument to help to ensure optimum operation of drying equipment. Ideal for precise Monitoring of moisture or Dew point in air or gas output from dryers systems or processes. Continuous monitoring of dewpoint results in reduced maintains cost and downtime caused by separated moisture. The main cause of corrosion in pneumatic systems. The analyzer uses a highly accurate Aluminium Oxide sensor and is an economic alternative to the chilled-mirror dew point type Meters. It utilizes embedded micro control-based circuits to give a direct-read out in dew point or other units and other units corresponding to sensor output-based and Psychometric equations. To achieve high accuracy it uses temperature compensation over the complete operational range.
Dew Point Meter Principle
By Cooling at consistent tension if the temperature of the air is decreased, the water fume noticeable all around will begin to gather at a specific temperature. This temperature is called dew point temperature.
Depiction
The Main Parts of the course of action are A glossy surface (reflect) is fixed with a thermocouple. A spout is giving a stream of air to the mirror. A light source zeroed in continually on the mirror. A photocell to recognize the measure of light reflected from the mirror. The activity of Dew Point Meter The mirror is continually cooled by a cooling medium. The cooling medium is kept up at a steady temperature. To this mirror is joined a thermocouple whose leads are associated with a millivoltmeter. Continually a light is made to fall in a point on the mirror and the measure of mirrored light is detected by a photograph cell. Presently an air stream is made to fall in a point on the mirror and the water-fume (dampness) contained noticeable all around begins consolidating on the mirror and they show up as little drops (dew) on the mirror. This dampness (dews) framed on the mirror lessens the measure of light reflected from the mirror and it is recognized by photocell. When interestingly, there is an adjustment of measure of sent light; it turns into a sign of dew arrangement. In this case (that is, the point at which the due development is recognized first), the temperature demonstrated by the thermocouple connected to the mirror turns into the dew point temperature. Along these lines, this plan is utilized to decide the time at which the dew shows up interestingly and dew point temperature.
