Dayu Electronics Pile Foundation Testing Transducers, Borehole Quality Inspection Transducers for Detection of Underground Trench Width and Trench Depth

The borehole quality inspection transducer operates in water or mud and is primarily used for distance measurement.

Applications include: borehole quality inspection instruments, ultrasonic borehole and trench inspection instruments, and caliper loggers.

For bored cast-in-place piles: detection of borehole diameter, hole depth, verticality, locations of collapse-induced diameter expansion, locations of collapse-induced diameter reduction, and inclination orientation.

For diaphragm wall excavation trenches: detection of trench width, trench depth, locations of collapse-induced diameter expansion, locations of collapse-induced diameter reduction, and inclination orientation.

For branch piles and under-reamed piles: inspection of the effectiveness of diameter expansion at the base.

Recommended borehole quality inspection transducers: KDYW-88-200B, KDYW-88K-200AE, DYW-64K-200AD, etc.

KDYW-88K-200B 

Frequency: 88 kHz ±5%;

Sensitivity:

Immerse the transducer in a water tank. With a no-load driving voltage of 500 Vpp, aimed at a reflector at a distance of 0.7 m, transmitting and receiving with the same transducer, the raw echo amplitude without any circuit processing is 5.0 V.

DYW-64K-200AD

Frequency: 64 kHz ±5%;

Sensitivity:

Immerse the transducer in a water tank. With a no-load driving voltage of 500 Vpp, aimed at a reflector at a distance of 0.7 m, transmitting and receiving with the same transducer, the raw echo amplitude without any circuit processing is 2.0 V.

KDYW-88K-200AE (for river flow measurement)

Frequency: 88 kHz ±5%;

Sensitivity:

Immerse the transducer in a water tank. With a no-load driving voltage of 500 Vpp, aimed at a reflector at a distance of 0.7 m, transmitting and receiving with the same transducer, the raw echo amplitude without any circuit processing is 5.0 V.
