One  thing that your comments encourage me to revisit is the way the 
cover over  the sensor is made.  It is made of 1/4/inch particle board 
and a  little heavy on the heavy side.  I is just sitting on the base 
frame  of the sensor, held down by it's own weight.  There are soft 
plastic  feet attached where the contact is made to the  frame. 


Hi Larry,
 
    You want to make a cover which rests on the floor  NOT on the seismometer 
base. Put a single sheet of bubble wrap over it with the  corners folded in. 
1/4" particle board won't give much thermal protection.
    Regards,
    Chris
