Pressure/ TECHNOLOGY DESCRIPTIONVaisala BAROCAP Sensor for MeasuringPressureFirst introduced in 1985, Vaisala BAROCAP is a silicon-based micromechanical pressure sensorthat offers reliable performance in a wide variety of applications, from meteorology to industrialmeasurements. Combining two powerful technologies – single-crystal silicon material andcapacitive measurement – BAROCAP sensors feature low hysteresis combined with excellentaccuracy and long-term stability.How It WorksBAROCAP is a micromechanicalsensor that uses dimensional changesin its silicon membrane to measurepressure. As the surroundingpressure increases or decreases, themembrane bends, thereby increasingor decreasing the height of thevacuum gap inside the sensor. Theopposite sides of the vacuum gap actas electrodes, and as the distancebetween the two electrodes changes,the sensor capacitance changes.The capacitance is measured andconverted into a pressure reading.The BAROCAP sensor’s properties– good elasticity, low hysteresis,excellent repeatability, lowtemperature dependence, andsuperior long-term stability – arethe result of its single-crystal siliconmaterial. The capacitive structuregives the sensor its wide dynamicrange and provides a built-inmechanism for overpressure blocking.148Typical Applications forBarometric PressureMeasurementBarometric pressure measurementhas a wide variety of applicationswithin meteorology. Pressure data isrequired for estimating the amountof precipitable water vapor in theatmosphere. Typical applicationsinclude weather stations, data buoys,GPS meteorology, and environmentaldata logging. Barometric pressuremeasurement is also used in hydrologyand agrology applications.Barometric pressure data is alsorequired in several industrialapplications. It is measured in pressuresensitive industrial equipment, such aslaser interferometers and lithographysystems, aviation applications, andin exhaust-gas analysis. Metrologicalapplications include laboratorypressure standard measurementsand environmental monitoring incalibration laboratories.BAROCAP in Brief Over 25 years of accuratepressure measurement Silicon-based capacitivesensor for absolute pressuremeasurement Barometric pressure range500.1100 hPa 50.1100 hPa pressure rangeavailable for industrialapplications Process pressure measurementrange 1.10 bar NIST-traceable pressuremeasurementBAROCAP’s Unique Benefits Low hysteresis, highrepeatability Superior long-term stabilityTolerates harsh conditions
BAROCAP Applicationsfor Measurements inPressurized SystemsVaisala DRYCAP dew pointinstruments have a long historyof providing reliable and stablemeasurements in compressedair systems and SF6 insulationgas monitoring in high-voltageequipment. In addition to theneed for dew point measurement,these two applications also sharethe need for accurate and stablepressure measurement. Vaisala hasintegrated its DRYCAP and BAROCAPtechnologies into a range of productsthat offer a unique combination ofpressure and dew point measurementfor pressurized systems.In compressed air, combiningdew point measurement with liveprocess pressure data provides aunique advantage: The conversionof measured pressure dew point toatmospheric pressure or ppm unitis available online, eliminating thepossibility of any ambiguity in the dewBAROCAP sensor.point data. This is important becausechanges in the pressure of the gasbeing monitored alter its dew point.Combined dew point and pressuremeasurement in SF6 gas monitoringof high-voltage equipment providesa superior tool for assessing thecondition of SF6 insulation. Leakagescan be immediately detected andearly warning is given for moistureissues. Measuring dew point,pressure, and temperature enablesthe calculation of SF6 gas density,normalized pressure, dew point atatmospheric pressure, and ppm – allessential elements in SF6 monitoring.View the complete range of Vaisalaproducts for combined pressureand dew point measurement atwww.vaisala.com/pressure.PressureVaisala offers a range of professionalgrade barometers for both indoor andoutdoor use.

Thecritical breakthrough came onthe brink of the project deadline.The first BAROCAP sensors weredelivered to two icebreakers andthe Helsinki Telephone Company.BAROCAP sensors have traveledto places where no human has everFor more information, visitwww.vaisala.com or contactus at sales@vaisala.comset foot, including as part of severalMars exploration missions and theCassini-Huygens mission to exploreSaturn and its largest moon, Titan.BAROCAP’s out-of-this-worldjourney continues with its inclusionin instruments that form part ofNASA’s Mars Science Laboratory,launched in November 2011.Ref.
