Quartz Seismic InstrumentationDigital force sensors have been applied to measure avariety of physical parameters including pressure,temperature, load, angular rate, weight, and acceleration.Resonant quartz crystals, that change their frequency ofoscillation with applied load, have many sensingadvantages over analog devices. These advantagesinclude the ease of measurements in the time domain,remarkable resolution, high accuracy, low powerconsumption, excellent long-term stability andinsensitivity to environmental errors. Thus quartz sensortechnology may also meet some needs of the seismiccommunity.Paroscientific, Inc.
