 No. 67 | 2008.3.6                             주요내용: Humidity Sensor for Fuel Cells

       

    Fuel Cell Humidity Sensor .....  VIASENSOR HS-1000


    비접촉식 laser absorption spectroscopy 방식을 이용하여 연속적으로 흐르는 gas 속에 포함되어 있는 water vapor를
    빠르고 정확하게 측정할 수 있습니다.


     Fuel cell Gas Measurements


    Quickly verify the accuracy and stability of humidification equipment
    Measure gas humidity in and out of fuel cell to verify mass balance
    Allows user to experiment confidently with a range of typical fuel cell conditions such as humidity,
           temperature and flow rates

  • Accurate, rapid and reliable readouts of
        water vapor content in a given space
  • In-line testing functionality for small or
        large applications
  • Measurement range from 40 to 1000
        millibar (30° C to 100° C dew point)
  • Real-time Data Plotting Software
  • Response time as fast as 1.6 seconds
  • Measurements that are independent of gas
        composition, pressure, or flow rates
  • The ability to test with confidence in a
       wide range of conditions including
       temperature, humidity, and gas flow
       rates.

     







  • System Configuration & Features

    Heated Sample Chamber
    Dew point measurement from 30
    ºC (40mB) to 100ºC (1000mB)
    Achieves 80ºC in less than 20 minutes

    Continuous Reading with Rapid Response Time
    Response time as fast as 1.6sec for gas flows greater than 0.4L/min
    Transient changes in humidity are measured and displayed in real time

    Measures Molicular Absorption of Water Vapor
    No interference from entrained liquid droplets
    No gas composition or pressure dependence
    No interference from typical fuel cell gas stream background components
    Measurement accuracy & reliability are not dependent upon flow rate
     
    Non Contact Optical Measurement
    Flow-through design for accurate measurement
    Contaminants in gas will not damage sensor or cause drift in readings
    No drift in calibration, even after incidental condensation in sample chamber
    Sensor cannot contaminate gas stream

    Continuous RS-232 Serial Output Data
    Water partial pressure (mB)
    Sample chamber temperature (ºC)
    Spectrum diagnostics
    Simplified data collection

    Data Logging Software
    Real-time plotting of dew point
    Readout of sample cell temperature
    System status indication light for known device readiness and condition
