NOTES
1. Short duration shock pulses, such as those generated
by metal-to-metal impacts, may excite transducer
resonance and cause linearity errors.
SPECIFICATIONS
The following performance specifications conform to ISA-RP-37.2 (1964) and are typical values, referenced at +75°F (+24°C) and
100 Hz, unless otherwise noted. Calibration data, traceable to National Institute of Standards and Technology (NIST), is supplied.
