 The Endevco Model 2270M8 Transfer Standard Accelerometer
is designed for the calibration of back-to-back working
standards used in comparison calibrations. It is used
extensively in calibrating standard accelerometers built
into the armatures of vibration exciters, such as the
Endevco Model 2901, or comparison standard accelerometers,
such as the Endevco Model 2270. The Model 2270M8 is particularly
valuable as a calibration source when the working standard
is to be used at frequencies up to 20,000 Hz.
The Model 2270M8 is supplied with an absolute reciprocity
calibration at 100 Hz. In addition, a comparison calibration
from 20 Hz to 10,000 Hz, including a graph of sensitivity
versus frequency, is supplied with all results given in
a comprehensive report showing traceability to the NIST.
Optional calibrations to extend the frequency response
down to 2 Hz or up to 20,000 Hz are also available.
Features:
• Transfer standard accelerometer for calibration of back-to-back
working
standards and reference standards built into shakers
• Stable P-10 crystal material
• High (55 kHz) resonance frequency
• Electrical isolation
• Supplied with reciprocity calibration at 100 Hz traceable
to the NIST
