The AVW4 provides amplification and signal conditioning for the frequency signal of up to four vibrating-wire or vibrating-strip transducers. Compatible sensors include pressure, load, strain, or even vibrating-wire temperature sensors. The recommended frequency range is 1000 to 9900 Hz (up to 5000 Hz in the CR5000).Read More
The AVW4 is available as a replacement part or as needed for continuity or compatibility, but we recommend the AVW200-series interfaces for all new applications. The AVW200-series interfaces are much more accurate and feature a high degree of noise immunity for your vibrating-wire measurements.
The AVW4 provides amplification and signal conditioning for up to four vibrating-wire pressure, load, strain, or temperature sensors. The recommended frequency range is 1000 to 9900 Hz (up to 5000 Hz in the CR5000).
|Frequency Sweep Range||1000 to 9900 Hz (performance optimized for greater than 1000 Hz)|
|Number of Vibrating-Wire Sensors Measured||Four vibrating-wire sensors connect to the AVW4. Additional sensors can be measured by using an AM16/32-series multiplexer.|
Vibrating-wire/strip transducers are measured by the VibratingWire Instruction in CRBasic, and by Instruction 28 (Vibrating Wire) in Edlog. The datalogger produces a swept-frequency excitation, then measures a specified number of cycles of the sensor's resonant frequency.
