Description
Overview
GAOTek analog vibration data logger is a kind of geotechnical in-situ monitoring instrument, which is suitable for the calculation of frequency signals output from steel string type sensors and temperature collection. It can be used for stress, strain, deformation, seepage pressure and other physical quantities monitoring and safety and stability analysis of dams, bridges, embankments, transportation and municipal projects and high slopes.
Features
- Adopt upgraded version of fully isolated RS485 interface
- Anti-lightning and anti-interference
- Compatible with all single coil vibrating wire sensors
- Built-in constant current excitation circuit
- Provide acquisition solutions for vibrating wire sensors
