Dew point sensor FA 300 Ex
|
| | Special features
• Robust design
• Pressure-tight up to 300 bar
• Long-term stable humidity sensor,approved for years
• 4...20 mA analogue output in 2-wire technology
• Further parameters adjustable via software:
% RH, g/m3, mg/m3, ppm V/V, g/kg
• CS Service Software for data storage and calibration
(for use in non-explosive area)
FA 300-2 Ex measures the dew point resp. the pressure dew point in explosive areas of Zone 1.
Protection class: FA 300-2 Ex: II 2G EEx ia II C T4
With the Atex approval for Zone 1 the established dew point measuring instruments FA 300-2 Ex can now be used in explosive areas of the industry as well.
FA 300-2 Ex may only be used in connection with approved Ex-rated power supplies or safety barriers or galvanic separating elements with max.:
U0 = 30 V max.
I0 = 100 mA max.
P0 = 1 W max.
