OVERVIEW

The leak detection alarm triggers an alarm when just a few drops of liquid make a conductive path between the conductivity pins. The pins are gold plated so they won’t corrode. Conductivity sensing allows the flexibility of running from battery with near zero drain.  Another advantage is that there is no calibration required ike capacitance sensors.

BEST FOR TRACE LIQUIDS

There are other ways to sense the presence of liquid of course, but nothing matches the precision of conductivity pins to detect a thin film of liquid at the bottom of a containment pan. This matters because detecting early can give a warning weeks or months earlier than other methods of detection. Perfect for containment tanks where there should not be any liquid.  The sensing pins are kept off the bottom by a couple of mm so as to eliminate false alerts that may be caused by condensation.

BATTERY POWER POSSIBLE

In addition, the conductivity sensor can be powered by battery – in fact the batteries last so long, there really isn’t any reason to use line power.  This is a limitation of capacitance, ultrasonics, tuning fork, optical sensors among other methods.
