I'm wondering about electronics for a tiltmeter with capacitive sensors I'm building.  
My current plan is to use a transformer coupled bridge, current-to-voltage amplifier, 
phase sensitive detector, followed by filter and final gain.  I have a circuit diagram for 
this scheme, but it's circa 1970 and I assume it can be improved with modern chips.  
Any suggestions?
