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.

Dew Point transmitter | vasthi instruments

 Dew Point transmitter. Humidity/Temperature transmitter. Relative humidity transmitter.

 Humidity transmitters provide electrical outputs that are proportional to humidity inputs.

 Variables Measured

They measure variables such as relative humidity, absolute humidity, specific humidity, moisture content, dew point, temperature, and pressure.

 ·  Relative humidity is a measure of the amount of water in the air compared with the amount of water that the air can hold at the measured temperature.

·  Absolute humidity is the mass of water vapor in a given volume of air.

·  Specific humidity is absolute humidity divided by the total mass of the given volume of air.

·  Moisture content or water content is the ratio of water mass to total mass.

·  Dew point is the temperature to which air must be cooled in order for saturation to occur.

·  Pressure and temperature measurements come from devices that include additional probes.  

Humidity Transmitter Technologies

Humidity transmitters use several technologies.

 ·  Capacitive devices contain a dielectric material whose properties change as humidity is detected and capacitance increases.

·  Resistive devices exhibit changes in impedance in response to humidity.

·  Humidity transmitters that use chilled mirrors are cooled to a specific temperature, the dew point, at which moisture begins to condense on the surface.

· Electrolytic devices measure moisture proportional to the current needed to electrolyze it from a desiccant.

·  Infrared (IR) instruments use the infrared spectrum to measure the absorption of moisture.

·  With microwave-based devices, the amplitude and phase of a microwave signal is affected directly by the amount of moisture in a material.

· Psychrometers determine relative humidity by measuring the temperature difference between two thermometers, one wet and one dry.

·  Strain gauges or piezoresistive elements measure the expansion of materials that absorb water.

·  Nuclear humidity transmitters measure how neutrons are slowed by the presence of moisture in a material.

 Specifications

Selecting humidity transmitters requires an analysis of performance specifications and features.

 Performance Specifications

Performance specifications include:

 ·  Operating temperature is the temperature range in which devices are designed to operate.

·  Relative humidity range and dew point range are ambient ranges that can be measured with a linear response.

·  Relative humidity accuracy and dew point accuracy are percentages that indicate the closeness of a computed amount to its true value.

Compensation

Some humidity transmitters are temperature-compensated and maintain constant output readings across a range of temperatures. Other devices are pressure-compensated.

 Features

Features for humidity transmitters include:

 ·  Self-calibrating devices will recalibrate themselves between uses.  

· Self-testing and diagnostic devices notify users when an internal fault condition is detected.

·  Data logging devices are capable of logging and storing data.  

· Event-triggered humidity transmitters can be configured to capture or log data when an event occurs.

· Battery-powered devices use batteries for full operation, not just backup.

Output and Displays

Humidity transmitters differ in terms of display type, electrical outputs, and digital outputs.

 There are three basic types of displays.

 ·  Analog meters or gauges use needles or light emitting diode (LED) indicators.

·  Digital readouts are numerical or application-specific displays.

·  Video display terminals (VDT) include cathode ray tubes (CRT) and flat panel displays (FPD).

Outputs

Electrical outputs for humidity transmitters include analog currents, analog voltages, frequencies or pulses, and switches or relays. Digital outputs include Ethernet, modems, parallel interfaces, serial interfaces, small computer systems interface (SCSI), transistor-transistor logic (TTL), and universal serial bus (USB).
