Measuring Dew Point In Compressed Air Drying

What is dew point, anyway?

Dew point is one of the most important parameters associated with the quality of compressed air. It can be defined as the temperature to which air must be cooled for the water vapor within to condense into dew or frost. At any temperature, there is a maximum amount of water vapor that the air can hold. This maximum amount is called the water vapor saturation pressure. If more water vapor is added beyond this point it will result in condensation.

Where is dew point measured and why?

Dew point is often measured on the supply side of a compressed air system. The measurement values can be shown directly on a display or on the dryer’s control panel. These values indicate a dryer’s performance and quality – and can also control desiccant tower regeneration to reduce energy consumption. Moisture contamination increases operating and maintenance tasks and costs in numerous ways. Whatever the source of the moisture, discovering the problem early on means that corrective actions can be implemented faster. This helps to avoid major problems that could lead to long and costly service breaks and lack of capacity.

How are dew point instruments installed?

The main installation steps involve isolating the sensor, regulating the flow, avoiding a local pressure drop, and selecting the tubing material while minimizing installation costs.

Why Choosing Dew Point Sensors from Dpstar?

High quality dew point measurement is essential to process efficiency, safety and profitability. In fact, the quality of measurement equals the quality of your process. Vaisala DRYCAP® sensors provide the highest accuracy over the widest dew point range on the market, plus the fastest response time and extremely rapid recovery from condensation. Its unique auto-calibration function ensures superior stability, giving you low maintenance and peace of mind.

Our unique sensor technologies cover the full dew point range with optimized instruments for practically any compressed air system. What is your system’s critical dew points? Demand or supply side? Special application and instrument requirements? Increasing the life of your compressed air system, improving process quality and lowering costs is now easier than ever. Vaisala DRYCAP® and HUMICAP® sensor technologies ensure accurate, reliable measurements with excellent long-term stability and fast response. All Vaisala sensors withstand exposure to contaminants like water spikes, ambient humidity, compressor oil and chemical impurities. They also have the fastest wet-to-dry response time on the market and minimal drift that allows for a long 2-year calibration interval. The DRYCAP® polymer sensor technology incorporates unique innovations such as the patented auto-calibration feature. This autocalibration maintains the specified accuracy by warming the sensor at set intervals to indicate a possible offset drift to the measurement electronics for automatic correction.

Enjoy Easy Installation & Spot-Checking

When it is undesirable or unfeasible to directly measure the air, sampling is needed. This may be due to a high process temperature, the need to protect the sensor from water spikes, wanting the added convenience of installing and removing the instrument from a pressurized process without shutting down the line, or wanting to make the measurement in a more convenient location. To get a representative sample of the process gas, Vaisala offers a variety of sampling cells that can be adapted to incorporate the necessary sensors into different sized systems. Vaisala offers a handheld dew point meter for spot-checking and validation on site. Its probe can be inserted directly into pressurized processes, and it responds rapidly in both ambient and process conditions.
