With an AVW200 vibrating-wire analyzer module, your data logger can measure vibrating-wire strain gages, 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. The VSPECT technology is protected under U.S. Patent No. 7,779,690.
