A Dew Point Analyzer is an instrument used to measure the moisture content in gases.
It determines the temperature at which water vapor condenses into liquid, known as the dew point.
The analyzer is commonly used in industries like oil and gas, power plants, and compressed air systems.
It helps prevent corrosion, condensation, and damage to equipment caused by excess moisture.
The device works using sensors such as chilled mirror, capacitive, or aluminum oxide types.
In a chilled mirror type, the gas is cooled until condensation forms on a mirror surface.
The temperature at which condensation occurs is recorded as the dew point.
Other sensor types measure changes in electrical properties caused by moisture levels.
Dew point analyzers provide continuous monitoring for process control and quality assurance.
Regular calibration and proper maintenance are essential for accurate and reliable measurements.
Measurement Technologies: Often use ceramic metal-oxide sensors (impedance-based) for moisture, or chilled mirror technology for highly precise hydrocarbon dew point detection.
Versatility: Suitable for measuring moisture in compressed air, industrial gases, and natural gas.
Portability & Design: Available as portable, battery-operated units with data loggers or as fixed, loop-powered transmitters for in-situ monitoring.
Output Signals: Provide output options like
, RS485/Modbus RTU for integration into control systems.
Protection: High-performance models offer IP66/IP67 ratings, explosion-proof, or hazardous area (ExD) certifications
Operating Pressure: Ranging from atmospheric to high-pressure systems
Response Time: Often designed for fast, real-time measurements in seconds to minutes.
Calibration: Often includes traceable, long-term stability with, in some cases, NIST certification.
