Humidity / TECHNOLOGY DESCRIPTION Vaisala HUMICAP® Sensor for Measuring Relative Humidity In 1973, Vaisala introduced HUMICAP ®, the world’s first thinfilm capacitive humidity sensor. Since then, Vaisala has become the market leader in relative humidity measurements, and thin-film capacitive humidity sensors have developed from one company’s innovation into a global industry standard.
Vaisala INTERCAP® Sensor ▪ Same measurement principle as in the HUMICAP® sensor ▪ Factory pre-calibrated - no additional calibration or adjustment needed ▪ ▪ Fully interchangeable Humidity In building automation, optimizing both the temperature and relative humidity of the indoor environment enables a greater level of comfort for occupants than optimizing temperature alone.
How to Choose the Right Instrument for Measuring Humidity and Dew Point What is Humidity? An Introduction to Humidity Parameters Partial Pressure of Water Vapor Humidity is simply water in its gaseous phase, properly called water vapor. Because water vapor is a gas, most of the common gas laws apply to it, including Dalton's law of partial pressures.
Effect of Pressure on Humidity Dalton's law states that a change in the total pressure of a gas must have an effect on the partial pressures of all of the component gases, including water vapor. If, for example, the total pressure is doubled, the partial pressures of all component gases are doubled as well. In air compressors, a pressure increase "squeezes" water out of the air as it is compressed.
Mixing Ratio The mixing ratio (x) is the ratio of water vapor mass to the mass of dry gas. It is dimensionless but often expressed in grams per kilogram of dry air. The mixing ratio is mainly used in drying processes and HVAC applications for calculating water content when the mass flow of air is known. Wet Bulb Temperature Traditionally, the wet bulb temperature (Tw) is the temperature indicated by a thermometer wrapped in a wet cotton sheath.
The Right Instrument for High Humidity In many applications it is advisable to isolate the probe from the process with a ball valve to enable the removal of the probe for maintenance without shutting down the process (see figure 3). Environments with >90%RH are defined here as high humidity environments. At 90%RH a difference of 2°C can cause water to condense on the sensor, which in an unventilated space may take hours to dry. Vaisala humidity sensors will recover from condensation.
In a pressurized system a sample pump isn’t needed as the process pressure induces a large enough flow to the sampling cell. When measuring dew point with a sampling system, trace heating should be used when the ambient temperature around the cooling coil or connecting tube is within 10°C of the dew point temperature. This prevents condensation in the tubing that connects the dew point instrument to the process.
Humidity manufacture and the measurement on site – introduces measurement error. The sum of these potential errors is the uncertainty of the measurement. When selecting a humidity sensor, consider the following factors associated with accuracy: • Linearity over the working range • Hysteresis and repeatability • Stability over a period of time • Temperature dependence of the sensor Humidity sensors from Vaisala.
cleaning agents. The chemical purge heats the sensor at regular intervals to remove chemicals that may have accumulated over time. The Importance of Electromagnetic Compatibility (EMC) There are many standards defining the ability of products to withstand external electrical interference. In addition, the product must not generate emissions that can cause interference to sensitive equipment.
Humidity Humidity Instrument Calibration In calibration, the humidity reading of an instrument is compared against a portable reference. The reference should be regularly calibrated and provided with a valid certificate. When selecting one of the many calibration methods, time, cost, technical requirements, expertise, and the unique needs of the organization must be balanced.

Moisture in Oil / TECHNOLOGY DESCRIPTION Vaisala HUMICAP® Sensor for Measuring Moisture in Oil Water is a common contaminant in industrial oils. Water contamination deteriorates the performance of the oil, be it used for lubrication, cooling, insulation or other purposes. High moisture content increases the risk of corrosion, overheating, machine malfunction and other problems and can ultimately lead to costly failure and unscheduled downtime.
In contrast to traditional measurement techniques, water activity measurement is independent of oil type. Regardless of the saturation point of the fluid, water activity measurement always provides a true indication for the risk of free water formation, even when the saturation point is increasing or decreasing. In its simplicity, water activity value is understandable at a glance. Trends can be quickly identified.
www.vaisala.com MMT330 Moisture and Temperature Transmitter Series for Oil The display shows measurement trends, real-time data, and measurement history. The MMT330 transmitter family offers reliable performance for the demanding measurement of moisture in oil.
Water Content as ppm Conversion The display alarm allows any measured parameter to be tracked, with freely configurable low and high limits. In addition to water activity, the MMT330 can output ppm, the average mass concentration of water in oil. Vaisala has this conversion readily available for mineral transformer oil. Versatile Outputs and Data Collection For serial interface the USB connection, RS232, and RS485 can be used.

Carbon Dioxide / TECHNOLOGY DESCRIPTION Vaisala CARBOCAP® Sensor for Measuring Carbon Dioxide First launched in 1997, the Vaisala CARBOCAP® carbon dioxide (CO2) sensor features a groundbreaking innovation – the micromachined, electrically tunable Fabry-Perot Interferometer (FPI) filter for built-in reference measurement.
Vaisala CARBOCAP instruments are well suited to a wide range of applications, from ppm (parts per million) to percentage-level CO2 measurements. Since CO2 is harmful in high concentrations, it is present at percentage levels only within closed processes such as fermentation and controlled-atmosphere storage environments. Percentage-level measurements are also typical in life-science applications such as CO2 incubation.

Weather / TECHNOLOGY DESCRIPTION Vaisala Wind and Weather Sensor Technologies for Measurements in Industrial Applications Vaisala's long history in wind and weather measurements started already in the 1930s from the development of a radiosonde to measure the conditions in the upper atmosphere. Today, Vaisala wind and weather instruments are used in dozens of applications and industries all over the world.
Vaisala Sensor Technologies for Wind and Rain Measurements Vaisala WINDCAP® Sensor Vaisala RAINCAP® Sensor Vaisala WINDCAP Ultrasonic Wind Sensor uses ultrasound to determine wind speed and direction. The sensor has no moving parts, which makes it independent of the limitations of mechanical wind sensors such as friction, inertia, time constant, over-speeding, and starting treshold.
