Neil - what you have shown is a good strategy for dealing with noise which is coupled electrostatically. If there are magnetic noise sources, this may not be adequate. The best strategy overall is to have the sensor inside a faraday cage and make the cable shield continuous with that cage. Of course, that is rarely practical. The next best thing is to use the shield as the ONLY ground reference for the sensor, and possibly add a ferrite choke around the entire cable if there is a noise source >10MHz or with fast edges.
