Vibrating Wire Strain Gauges(Surface)

Type VWS-SM vibrating wire surface strain gauge is mainly used for strain monitoring of bridges, highways, railways, subways,tunnels, pile foundations and other structures. It can be welded on the surface of steel structures or bolted on the surface of various structures for long-term automatic monitoring and regular detection. The built-in temperature sensor of the strain gauge can monitor the ambient temperature at the same time. Advantages of vibrating wire strain gages are that the frequency output is immune to electrical noise, is tolerant of wet wiring commonly found in geotechnical applications,and can transmit signals over many kilometers without loss of signal.

FGB Strain Gauges

FGB Strain Gauges

Type FBG-SG-SM surface fiber grating strain gauge can meet the needs of surface strain measurement in various occasions. It can be installed on the surface of concrete or steel structure, mainly used to measure the surface strain of concrete and steel structure. The external strain transmits the strain to the internal fiber grating through the sensor mount, and the reflection center wavelength of the grating will change, and then the fiber grating demodulator performs demodulation analysis and calculates the strain value.

Vibrating Wire Eearth/Soil Press Gauges

Vibrating Wire Eearth/Soil Press Gauges

The model VWE series vibrating wire soil/earth pressure cells is an embedded soil pressure sensor, which is mainly used to measure the stress of soil inside structures such as earth-rock dams, soil lifts, slopes, roadbeds,retaining walls and tunnels. The main parts of the sensor are made of special steel, which can be used in harsh environments. It has excellent performance,good precision and sensitivity, excellent waterproof performance, corrosion resistance and long-term stability, etc. After the cable protection measures are perfected, it can be directly buried in the compacted soil which has higher requirements on the instrument.

Vibrating Wire Strain Gauges(Embedment Type)

Vibrating Wire Strain Gauges(Embedment Type)

Type VWS-EM vibrating wire embedded strain gauge can be buried in beam piles, pile foundations, supports, hydraulic structures, linings, piers and bedrock of various concrete structures for a long time to monitor its stress and strain. The build-in temperature sensor can simultaneously measure the temperature of the measure point, which is used for temperature correction of the embedded strain gauge. The biggest advantage of the vibrating wire strain gauge is that the sensor is simple in structure, reliable in operation, the output signal is a frequency signal, and the frequency output is not affected by electrical noise, and it can be transmitted for several kilometers without losing the signal. The sensor is mainly used for strain measurement inside concrete structures such as buildings, bridges, highways, railways, subways, tunnels,dams, foundation piles, etc.
