Daedong Instruments

Company Description

Daedong Instruments is manufacturers of high quality geotechnical Instrumentation. Daedong Instruments manufacturers a complete line of geotechnical instruments including strain gages, load cells. incllinometers, piezometers,
water level meters, Vibrating wire readout etc.

Geotechnical instruments are used for monitoring the safety and stability of civil structures such as foundations, dams, slopes, tunnels, embankments, slurry wall excavations etc.
The resonant frequency of vibrating wire is proportional to the strain or tension in the wire.

This fundamental relationship is utilized in a variety of configurations for the measurement of strain, load, force, pressure and tilt. Vibrating wire sensors are Daedong Instrumentsll known for their long term stability.
The advantage of vibrating wire sensors over more conventional types lies mainly in the sensor output which is a frequency rather than a voltage.
Frequencies can be transmitted over long cables without appreciable degradation of the signal caused by variations in cable resistance which
can arise from water penetration, temperature fluctuations, contact resistance or leakage to ground.
