The AVW211 is a vibrating wire interface that includes an internal 920- to 928-MHz spread-spectrum radio for wireless communication. The internal radio's frequency range is used in Australia and Israel. This vibrating wire interface allows our dataloggers to measure vibrating-wire strain gauges, pressure transducers, piezometers, tiltmeters, crackmeters, and load cells. These sensors are used in a wide variety of structural, hydrological, and geotechnical applications because of their stability, accuracy, and durability.

Benefits and Features

Provides better measurements by significantly reducing incorrect readings caused by noise sources
Interfaces two vibrating wire sensors; more sensors may be connected if an AM16/32B multiplexer is used
Self-checking diagnostics give continual feedback on sensor condition
High resolution—less than 0.001 Hz (industry standard is 0.1 Hz)
Low current drain
Remote, wireless operation with on-board radio
Interfaces both temperature and frequency measurements from vibrating wire sensors
