THE WORLD’S MOST CAPABLE DATA/VOD RECORDER!
Your Data Acquisition (DAQ) system could cause a failure of your testing program. When confronted by dust, high or low temperatures, moisture, or even rough handling, a typical DAQ systems will fail.
If you want to record acceleration, pressure, and other dynamic sensors under tough outdoor conditions, then the DataTrap II™ Data/VOD Recorder is the only rugged recorder that provides this capability and the optional ability to record explosives velocity of detonation (VOD) continuously along explosives columns in many multiple blastholes, along explosives samples, as well as to determine the delay times between blastholes.
RECORD DYNAMIC SENSORS
The DataTrap II™ Data/VOD Recorder can sample the data up to 10 MHz for quick changing signals to accurately record the peak of the signal and the shape of the waveform. This is critical for measuring dynamic air blast pressures and dynamic underwater pressures whose peaks occur at a very high frequency.
The DataTrap II™ Data/VOD Recorder is used to:
The unit can also have a slower sample speed to measure the gradual change over a longer period of time. The recording rate can be decreased to 1 Hz to allow a long sampling time. For example, the unit with Maximum Memory measuring 8 channels at 1 Hz will allow for 370 days of recording in a single file. With the slower record times, slower sensors can be recorded.
TEST EXPLOSIVES IN ONE OR MORE BLASTHOLES PER BLAST
Using the DataTrap II™ Data/VOD Recorder, VOD PROBECABLE can be placed in multiple holes to measure the VOD of the explosives in the hole, the timing of the holes, length of column of explosives above the booster, the location of the booster in the first hole, the timing of explosive decks, the effectiveness of the decking material and much more.
With the DataTrap II™ Data/VOD Recorder a single length of VOD PROBECABLE per channel multiple pieces of data can be collected. This will extend the functionality of a single channel of data. With the VOD Upgrade, the DataTrap II™ Data/VOD Recorder can use multiple channels to record multiple holes that are designed to function simultaneously.

The maximum sample speed of the DataTrap II™ Data/VOD Recorder is 10 MHz. This means that it can sample data at a rate of up to 10 million samples per second. This high speed sampling capability allows for precise and detailed measurements of fast-changing signals and provides granularity of the signal waveform.
The DataTrap II™ Data/VOD Recorder is designed to capture data from various sensors, such as pressure sensors, accelerometers, or any other ±10 Volt signal. It can record up to 8 different channels simultaneously, each capable of measuring data at the maximum sample speed of 10 MHz.
It is important to note that the DataTrap II™ Data/VOD Recorder also offers the flexibility to adjust the recording speed independently for each channel. The recording speeds can be set from as low as 1 Hz to the maximum of 10 MHz, depending on the specific requirements of the measurement.
By providing a high sample speed of 10 MHz, the DataTrap II™ Data/VOD Recorder enables accurate and detailed data acquisition, making it suitable for applications where fast-changing signals need to be captured and analyzed.
The maximum recording time of the DataTrap II™ Data/VOD Recorder is calculated by the following equation:
Total number of points / ((the number of tests) x (the number of channels active) x (sample rate of the channel)
The total number of points will be determined by the memory level in the unit. The Standard Memory of the DataTrap II™ Data/VOD Recorder is 128 MB (which is 67 million data points), Enhanced Memory is 256 MB (which is 134 million data points) and Maximum Memory is 512 MB (which is 268 million data points). The maximum sampling speed is 10 million samples per second.
Therefore, with maximum memory, one test and one channel measuring at the maximum speed, the recording time would be 26.8 seconds. With all 8 channels active at the same settings, the recording time would be 3.35 seconds.
The maximum number of tests that the memory can be divided into is 32 tests. This will allow the user to reduce the recording time that is captured if working with shorter tests. The division of the memory will allow the size of the files to be reduced that will allow for just the events to be captured without a lot of wasted time.
No, you will need the VOD Upgrade to record Velocity of Detonation (VOD) with the DataTrap II™ Data/VOD Recorder. The VOD Upgrade is an optional factory-installed internal upgrade specifically designed to provide VOD recording capability to each of the 8 channels of the DataTrap II™ Data/VOD Recorder.
With the VOD Upgrade installed, you will have the flexibility to select VOD or Scope input on each channel independently. This upgrade allows you to measure the VOD of explosives and capture the necessary data for analysis and evaluation.
It is important to note that the VOD upgrade utilizes the memory already present in the DataTrap II™ Data/VOD Recorder, so no additional memory upgrade is required specifically for VOD recording.
The VOD Upgrade for the DataTrap II™ Data/VOD Recorder provides the capability to measure Velocity of Detonation (VOD) on each of the 8 channels of the recorder. This upgrade allows the operator to select VOD or Scope input independently for each channel. The VOD Upgrade is an optional factory-installed internal upgrade specifically designed to enhance the functionality of the DataTrap II™ for VOD recording purposes.
The benefits of the VOD Upgrade include:

To measure the VOD of multiple boreholes using the DataTrap II™ Data/VOD Recorder, you can utilize the VOD PROBECABLE and take advantage of the recorder’s multiple channels. Here’s how it works:
In summary, the DataTrap II™ Data/VOD Recorder is designed to measure VOD in multiple blastholes simultaneously. By utilizing its multiple channels and VOD PROBECABLE, you can collect data from each blasthole and analyze various parameters to gain valuable insights into the blasting process.
When using the DataTrap II™ Data/VOD Recorder to record multiple boreholes, you can obtain various types of information. Here are some key details:
By recording multiple boreholes using the DataTrap II™ Data/VOD Recorder, you can gather a wealth of information related to the VOD, timing, length, location, and effectiveness of the explosives. This data aids in evaluating the blast performance, optimizing blasting techniques, and ensuring safety and efficiency in mining or construction operations.
Per channel, the DataTrap II™ Data/VOD Recorder has the capability to measure a maximum length of 1,000 meters of VOD PROBECABLE-LR “BLUE” in multiple blast holes per blast. This allows for flexibility in monitoring and recording data from various locations within a blast site.
Additionally, the DataTrap II™ Data/VOD Recorder has a practically unlimited length of coaxial cable that can be used to connect the recorder to a safe location. This is particularly useful in situations where the recorder needs to be placed at a significant distance from the blast to protect it from potential fly rock impact.
