Autoresonant Piezometer VW Model 4500AR

Autoresonant Piezometer VW Model 4500AR

The Model 4500AR “Autoresonant” Piezometer is designed for use with existing data acquisition systems inca

Description

The Model 4500AR “Autoresonant” Piezometer is designed for use with existing data acquisition systems incapable of reading standard (pluck and read) vibrating wire sensors. It can also be used where low frequency (< 20 Hz) dynamic measurements are required. Power comes from a 6-24 VDC supply, which yields a 5 V square wave output at the sensor frequency. This high-output offers excellent noise immunity and enhanced signal transmission over long (300 m+) cables. The Model 4500AR is available in standard pressure ranges, with corresponding resolution, linearity and accuracy
