The AVW100 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 AVW100 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 250 to 9900 Hz (up to 5000 Hz in the CR5000). It is similar in general design to our AVW1 and AVW4, but it is designed for use with frequencies that those interfaces do not support (i.e., 250 to 1000 Hz).
