  DESCRIPTION
  The Model 61 accelerometer is based on an
  advanced piezoresistive MEMS sensing element
  which offers exceptional dynamic range and
  stability. This unit features a full bridge output
  configuration with a temperature range from
  -20ºC to 85ºC. This unit exhibits superior shock
  survivability and a flat amplitude/phase response
  up to 3kHz.
