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. Power only with ALTHEN or ALTHEN approved current source IEPE** type power unit. Do not supply power to this device without current limiting, 20mA max. You will destroy the integral electronics.

    **IEPE = Integral Electronics Piezo-Electric

Mounting surface preparation (equivalent for metric screw)

  1. Prepare (or select) a flat mounting surface of at least 0.32 inch diameter. Surface should be flat to 0.001 inch TIR for best high frequency response.
  2. At the center, drill #50 (Ø 0.070 inch) x 0.20 inch (approx. 5.1 mm) deep.
  3. Tap #2-56 UNC-2B x 0.125 min depth.
  4. Clean the area carefully after machining to remove all chips and cutting oils.
