Abstract
According to one aspect, an apparatus includes a first printed circuit board (PCB), the first PCB including a first interface, and a corrosion sensor assembly. The corrosion sensor assembly including a second interface arranged to be coupled to the first interface, the corrosion sensor assembly further including a signal trace field and a plurality of components, wherein the signal trace field and the plurality of components are arranged to provide an indication of whether the apparatus is in an environment that is corrosive.
Claims9
A corrosion sensor assembly comprising:
- a printed circuit board (PCB);
- a first interface for connecting the PCB to a host PCB to provide power to the PCB, said first interface comprising a pluggable connection to the host PCB for electro-mechanically coupling or decoupling the corrosion sensor assembly to or from the host PCB;
- a plurality of traces formed on the PCB and comprising at least one test trace and at least one control trace;
- and
- a plurality of components to obtain data from signals flowing through said plurality of traces and identify changes to provide an indication when the host PCB is in an environment that is corrosive, wherein said indication is based on a comparison of the signals flowing through the test trace and the control trace.
