The AVW1 is available as a replacement part or as needed for continuity or compatibility, but Campbell Scientific recommends the AVW200-series interfaces for all new applications. The AVW200 interfaces are much more accurate and feature a high degree of noise immunity for your vibrating-wire measurements. The AVW1 provides amplification and signal conditioning for the frequency signal of one vibrating-wire or vibrating-strip transducer. 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).
