Abstract: A tape-drive condensation sensor includes a probe with first and second spaced-apart electrodes that define a passage for air flow within a pneumatic conduit. A voltage source is coupled between the electrodes and the voltage of the source and the spacing between the electrodes are adapted to pass a current when a drop of condensation forms between the electrodes. An alarm circuit is activated by the flow of current, the alarm being adapted to signal an event of discernible condensation.
