Notes

  1. Measured at 100 Hz, 1 g rms per ISA RP 37.2
  2. Linearity is % of specified full scale (or any lesser full scale range), zero-based best fit straight line method.
  3. Do not apply power to this device without current limiting, 20mA max, to do so will destroy the integral IC amplifier.
  4. Glass to metal seal connector. Mates with ALTHEN cable model AV6811Axx or AV6824Axx (xx = length in feet)

Accessories

Supplied accessories:

  1. Mounting Stud with 5-40 UNF to metric thread
  2. Accredited Calibration Certificate (ISO 17025)
