YieldPoint provides high quality, yet competitively priced, digital geotechnical instruments that offer the best price/performance in the marketplace today. The digital advantage can be summarised as follows:
These features save time and money!! For example (i) digital output signals contain information on the SensorID and SensorType so that networks and data-logging solutions require no configuration, and (ii) by providing sensors that display readout in real-world units (mm or inches, tonnes or tons), YieldPoint’s digital instrumentation empowers miners, technicians and engineers to make faster and more informed decisions. |

YieldPoint’s
newest state-of-the art GMM uses non-contact SPECTRE (Sonic Pulse
Extensometer/Contractometer Technology for Rock Engineering) technology
to provide a single point displacement measurement. An on-board
microcontroller provides temperature compensation and outputs a digital
signal. Both the resolution (<0.01mm) and accuracy (0.5%FS) are
significantly better than for similarly priced technology. The
inherently digital form of the signals eliminates the necessity for
expensive analog-to-digital conversion and results in low cost networked
monitoring solutions.

| Multi-Point Borehole Extensometers (MPBXs) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The
DETECT-EX Multi-Point Borehole Extensometer is specifically designed to
accurately and reliably measure displacement at 3,4, or 6 points around
underground excavations. The distinguishing feature of this technology
is the
Single Rod Design that locates the
displacement transducers at specified distances along the extensometer
probe. By virtue of this design movement is measured directly at
location, so that the accuracy of the individual transducers represents
that for the overall instrument without errors related to long rods.

| Tiltmeters | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
TILT
sensors are based an either electrolytic (TILT-EL) or MEMS (TILT-SG)
transducers and are available in uni-axial (TILT-EL only) and biaxial
configurations. For larger range monitoring (+/- 30arcdeg, with
0.01arcdeg res) use the TILT-EL30 or TILT-SG30, and for narrow range
(+/-2arcdeg with 1 arcsec res) use the TILT-EL02. TILT sensors can
provide a cost-effective monitoring solution for monitoring an
excavation roof ,a brow, a fill bulkhead, or a sill mat.

The
Digiplucker
is a small, low cost units that enables
YieldPoint’s digital peripheral components to read (MIU or
SensorSync for PalmOS device), store (SLUG) or transmit (DESTINY) data
from vibrating wire (VW) transducers such as load-cell, stress cells and
piezometers. The user simply connects the leads of the VW sensor to a
terminal block housed inside the unit and then treats the sensor like
any other YieldPoint sensor. The unit outputs the temperature recorded
by the thermistor in degC (0.1degC resolution) and the period of
vibration of the wire in microsecs
(0.1 microsec resolution). more... |
