American deep special xtr-100 dew point mete

  American SHENTE xtr-100 dew point meter is provided by Beijing huituo Information Technology Co
, Ltd

Xtr-100 two-wire dew point transmitter can quickly and accurately measure the humidity of dry air or other gases in the range of - 100 ℃ ~ + 20 ℃ Application fields: including petrochemical, natural gas, dry gas and compressed gas, generator cooling hydrogen, transformer and high-voltage switch insulation gas, welding gas and oxygen for ships and aviation Principle and structure: the inner core is a high-purity aluminum rod, the surface is oxidized into alumina film, and it is coated with a multi empty gold film
A capacitance is formed between the gold film and the inner core
Due to the water absorption characteristics of alumina film, when water vapor molecules are sucked into it, the capacitance value changes
The humidity can be obtained by detecting and amplifying the capacitance signal
Xtr-100 dew point meter principle: ultra thin film alumina capacitor with special HTF technology
