Overview
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).

Detailed Description
The AVW1 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 AVW1 provides amplification and signal conditioning for a vibrating-wire pressure, load, strain, or temperature sensor. The recommended frequency range is 1000 to 9900 Hz (up to 5000 Hz in the CR5000).
Specifications
| Frequency Sweep Range | 1000 to 9900 Hz (performance optimized for greater than 1000 Hz) |
| Number of Vibrating-Wire Sensors Measured | One vibrating-wire sensor connects to the AVW1. Additional sensors can be measured by using an AM16/32-series multiplexer. |

Data Logger Considerations
Programming
Vibrating wire/strip transducers are measured by the VibratingWire Instruction in CRBasic, and by Instruction 28 (Vibrating Wire) in Edlog. The data logger produces a swept-frequency excitation, then measures a specified number of cycles of the sensor's resonant frequency.
