Vibrating string collector

1.Introduction to Vibrating string collector

Vibrating string collector is designed to manage vibrating thread stress gauges and other geotechnical sensors for DAMS, Bridges, slopes and more.Vibrating string collector is a geotechnical in-situ monitoring instrument, suitable for frequency and temperature signal acquisition from vibrating string sensors.

Suitable for engineering industries such as dams, bridges, slopes, etc.

2.Vibrating string collector application scenarios

Bridges, tunnels, rail transit, water conservancy, buildings

3.Vibrating string collector product features

1.The equipment is small in size and light in weight, supports installation methods such as guide rails, snaps and other buckles, and is convenient to connect

2.Support three excitation methods: single pulse, multi-pulse, and resonance method

3.Low power design

4.The device can diagnose the sensor status

5.Compatible with all single-coil vibrating sensors, built-in constant current excitation circuit, and provides a collection solution for vibrating sensors with built-in thermistor temperature measurement method.

6.Acquisition accuracy ±0.05HZ, which can meet the long-term observation requirements of users for high-precision and high-stability projects.
