Photographs:

Electronics (logger and sensor) housed inside PVC pipe
Tygon tubing (1/8" ID inside, 1/4" ID outside) "connects" atmospheric port from pressure transducer to brass barb and from brass barb to atmosphere
Additional tygon tubing (1/8" ID) connects pressure transducer ports to inside barbs
Brass Barbs (one inside and one outside) & 3/4" Brass Nipple provide the through housing connection
Concrete block provides stability and mass (more mass is recommended) to counteract buoyancy of housing
Atmospheric tube can be attached to a 36" long threaded rod fixed to concrete block

Two housings in concrete block
