4.2 Measurement Rates
CDM-VW300 analyzers use patented techniques to measure sensors at rates
from 1 to 333.3 Hz. Systems that exclusively require rates slower than 1 Hz
should use a Campbell Scientific AVW200-Series Vibrating-Wire Spectrum
Analyzer.

analyzers
4.3 Integrated Thermistor Measurement
Many vibrating-wire sensors include an integrated thermistor to allow for
temperature compensation of the vibrating-wire measurement. The CDM-
VW300 supports thermistor measurements and the associated temperature
compensation required in some applications.
