Attach 3/4 in. watertight pipe to the top of the preamplifier. Secure
the threaded connection to prevent any leakage. For additional
defense against possible accumulation of condensation at the back
seal area of the sensor, fill the lower 3-4 inches (75-100 mm) of
conduit or extension pipe with a flexible sealant such as silicone.
