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 30ºC (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
