Ultrasonic Cross-hole Pile Testing system(4channels)
1. Standard: ASTM D6760 Standard Test Method for Integrity Testing of
Concrete Deep Foundations by Ultrasonic Crosshole Testing.
2. Applications of Product
It is specially established to detect the completeness of
foundation piles by means of acoustic-transmission method, which
can also be employed in such functions as the detection of
intensity via ultrasonic-rebound combined method, detection of
lacunas and cavity, detection of facture depth via ultrasonic
method and so on. A hoist of multi-channeled self-circulation can
accomplish measurement of six sections in the concrete
cast-in-place piles, which can greatly improve the efficiency of
detection compared with single-section or one-transmission and two-
receiving measurement instruments.
3. Characteristics of Function
- A hoist can simultaneously accomplish the measurement of six
sections, with 4 grades adjusting the hoisting speed. The hoisting
speed is above 60m/min.
- High-performance industrial ARM processor has a dominant frequency
up to 1 GHz. ARM Cortex A8, a brand-new high-performance processor,
is a heavily-customized Windows CE 6.0 real-time operating system,
which will enter into testing system 15 seconds starting-up later.
The system works all the more steadily and the power can be
directly turned off after saving the data when the measurement is
accomplished. The battery life can last above 8 hours.
- The first original adoption of transmit-receive radial sensor,
combined with pre-posed amplification techniques, is capable of
perfectly solving such industry complexities as dimness and
difficult interpretation of head wave. The size of transducer is
small, with a diameter of 25mm and a length of 20cm. The
measurement span of concrete is up to 8m.
- The wire spool of radial transducer employs a high-level steel
frame, which is sturdy and durable and not easy to deformation. A
collected circulation is added to the wire spool, which makes it
all the more free for the take-up and pay-off of wire. Six colors
of electric cables in radial transducer are available for free
choice.
- Original iteration algorithm of interpretation can automatically
make the accuracy of head-wave interpretation up to 99% under
complex conditions.
- A 10.4 inches industrial high-lighting and wide-temperature display
can be easily seen under the sun. It is equipped with high-level
resistive touch screen to easily cope with those on-the-spot
complex testing environments.
- The proficient and flexible operation of built-in software, the
accurate interpretation of head wave and free switch of color
schemes of display interfaces are making it possible to adapt
various working environments.
- The defects can be accurately fixed by means of real-time
repetition measurement and cryptographic measurement in the process
of measurement.
- It is characterized by a large storage space of 16GB, adoption of a
high-speed interface of USB 2.0 and can transmit data via USB.
- The professional data processing software can rapidly analyze the
data measured to yield a detection report, whose formats can be
freely customized.
- The outer casing is made of high-level alloy materials and has the
anti-sprayed water design, which is characterized by sturdy and
durable. The size of main engine is the smallest among the similar
products in terms of weight.
- The instrument is provided with high-level water-proof instrument
shelter to easily cope with the changes of different environment in
the wild.
