Do You Have a Need for High Speed Multi-Function Recorder?

rscasny
rscasny over 1 year ago

imageI have been speaking with a manufacturer who has a High Speed Multi-Function Recorder that it would like to roadtest. We are looking to see if there are some people on the community who have an immediate need of a recorder such as its DAS60 model .

Here's a description of the product:

It's a high-speed multi-function recorder with versatile channel configurability, high-speed sampling (1 MSa/s), a wide input range (±5 mV to ±500 V), large internal solid-state memory of up to 64 GB, and 9.5 hours of battery life. Each channel can record a different signal such as voltage, temperature, current or frequency simultaneously, using a common time base.

Here are some features:

  • Fast 1 MSa/s sample rate (memory mode) and 100 kHz bandwidth for capturing intermittent events
  • Accurately view and record signals from ±5 mV to ±500 and 424 VRMS
  • CAT III 600 V rated isolated channels
  • Wide 10-inch touchscreen TFT display
  • Capture mixed signals with one instrument, such as high voltage, current waveforms, temperature, and logic data
  • Battery life up to 9.5 hours
  • 64 GB (DAS60) and 32 GB (DAS30/50) internal solid-state memory
  • 6 analog input channels
  • 14-bit resolution
  • 16 logic input channels
  • Temperature measurements supporting thermocouples and Pt100/Pt1000 sensors (factory option on DAS30/50)
  • WiFi monitoring and control (standard USB WiFi dongle required)
  • 2 USB host ports and one LAN interface
  • 110 mm thermal printer (factory option)

Here are some of the common uses:

  • Measure signals ranging from small sensors to large electrical systems
  • Maintenance and failure analysis
  • Power analysis of single and three-phase systems

Here is some documentation:

    A typical example of how these types of instruments are used. This one is a baby unit, just 4 channels. There is probably a huge market of engineers who are looking to upgrade, because many of these…

    ROFL - When I first started as a field engineer, we had these brush recorders for troubleshooting.

    Just a very rough estimation: 64GB storage would mean, for 14bit resolution (so 2 bytes), about 32000 seconds of (single-channel) data, so about 9 hours of data at the highest sample speed. While I don't have a need in the sense of 'have an immediate project at hand and need to buy something like that without the RT' (hence I voted 'maybe') I can immediately think of 5 different things I would do with such a device (and for one of these I actually _did_ build a long-term data recorder several months ago)

    Argh!  You're killing me.  424VRMS.  Almost all of my power quality surveys would be on 480VRMS systems. Frowning2

    These are surprisingly useful!

    I have three recorders (including an older DAS240 which is lower-speed).

    These are the modern equivalent of chart recorders, kind of like an oscilloscope but for long-term logging and with rugged low- and high-voltage capable interfaces, and with isolation. Super-handy for even leaving on-site to capture an issue (e.g. brownout (since it has in-built battery!), mains voltages, current consumption, monitoring tank or pipe temperatures if there's a risk of Legionella for instance!).

    A lot of older recorders have very poor displays (and often have a built-in printer as a result), and lacked network interfaces, so you could only check things infrequently. These high-res TFT models are much more useful. Very nice for remotely checking issues that may be occuring on a site.

    Yes, if selected, I would like to test couple of SMPS PCB and other circuit boards,

    I,ve use strip chart recorders and built my own digital data recorders using FPGAs in the past or even used Xilinx/AMD ILAs with deep memory.  This would be interesting to test with sensor data to compare with data in memory devices as a check.

    with 16 bits of 14 bit resolution you could track 7 bit I/Q data in the 16 bits.

    it would be an interesting task to come up with a good use case for outside the lab testing.

    I wouldn't say I have an immediate need, but periodically a great instrument like this would be very useful.

    Drool is running down my chin. 

    The spec says 600v cat3 to ground, but the photo shows 500v on the jacks.

    Could you use a voltage divider or step down transformer to create a safe monitoring point within the equipment's 424VRMS range?

    This has bandwidth limited to 100 kHz,  would be interesting to see if it can be used for higher bandwidth with 3 dB down and DSP filter.

    Will easily measure PMSM, VFD like the recent one MCTPTX1AK324 (which would be probably a RT).
