DAC Express software is one of the most powerful data recording/logging software
packages available. Setup, monitor and record test setups in minutes.
Combine the DAC Express Environment with VTI Hardware
to Cover Any Application.
Our intuitive, easy-to-use GUI lets you quickly build flexible, high-performance
systems with repeatable accuracy.
Data Logger Configuration
The simple name understates its power. Focusing on low-speed measurements such as
temperature, strain, and more, the data-to-disk transfer rates of greater than 400
kSa/sec (for multiple modules) can be maintained while on-line monitoring displays
show key values for the operator.
Sometimes you need more than just analog data. If your job requires recording digital
states, relay settings, shaft rpm, pulse train rates, or similar parameters in addition
to analog signals, this system is the answer. You can easily configure a mix of
channel types.
Structural Strain Measurements
Stress and fatigue testing of large structures have special needs. VTI's solution
provides structural test engineers with the performance needed for these large scale
tests. The Ethernet controlled 48-channel, high-performance remote strain gauge
measurement unit offers built-in calibration and 24-bit resolution providing very
high data resolution and accuracy. Ethernet control allows for remote operation
reducing cable lengths and the RJ-45 connector reduces transducer connector costs.
The VTI solution also supports TEDS or smart transducers to further improve system
accuracy and reduce cable connection errors. The flexible VTI units support 1/4,
1/2, and full bridge configurations through software reconfiguration, eliminating
the need change hardware configuration to support mixed transducer types. VTI units
can be easily connected together using the VXI trigger bus for synchronized measurements.
Combined Dynamic and Static Measurements
Combining high-speed measurements of noise or vibration signals and low-speed measurements
of temperature, strain, and more, this is the workhorse system of its class. High-speed
sample rates can be set up to 196.6 kSa/sec/ch. Low speed scanned sample rates can
be set up to 1.25 kSa/sec/ch for 64 channels. In the standard configuration, all
data goes to the host PC hard drive. For higher data transfer rates, using the optional
VXI data disk, the high and low-speed data streams go to separate disks, ensuring
continuous data rates of up to 9.25 MSa/sec for high-speed measurements and more
than 400 kSa/sec for low-speed measurements.
