@R. Colin Johnson: thanks for the note. It would have been nice to have a summary of other competing products (instead of being ADI-centric! Not that I don't like ADI, a fine components company!). The accelerometer seems like a nice version of ruggedized products, a good step indeed for ruggedized MEMS. But the 13-by-8-by-2mm package seems huge! I have used smaller ones from Endevco (non-MEMS version) for similar applications. Hi temp, hi-Rel, ruggedized versions don't enjoy the volume benefits of their commercial cousins, so I would argue the non-MEMS versions of accelerometers can handily beat the ruggedized MEMS versions in price/performance.

Does anyone know what kind of temperatures are found in deep rigs or excavation?
