1.0 Principles of Operation
The SAAFShield Detecting Unit is the non-powered, sensing side of the
SAAFShield system that utilizes Quartz Crystal Microbalance (QCM)
technology to measure metal corrosion due to reactions with the
environment. The SAAFShield Detecting Unit works in combination with
the SAAFShield Reading Unit as part of a system that monitors atmospheric
corrosion in real time or on a periodic basis.
The SAAFShield Detecting Unit's oscillator Printed Circuit Board (PCB)
consists of specially marked tracking where electromagnetic induction
effects are significantly reduced in order to produce the most stable and
accurate frequency reading. As the metal-coated QCM corrodes, the
frequency of oscillation changes. The Detecting Unit has built-in
non-offgassing Ethylene Vinyl Acetate (EVA) foam spacers to prevent
unwanted movement of the QCMs within the enclosure.
