Dynamic Signal Data Logger

That depends on the highest frequency you want to capture. A rule of thumb is to sample at least 5 to 10 times faster than the maximum frequency of interest. For structural vibration, 1–2 kHz per channel is often enough; for impact testing or acoustic emission, you may need 50 kHz or more. We usually help match the logger to your sensor bandwidth so you’re not paying for sampling speed you won’t use.

Yes, many dynamic signal loggers support multiple input modes per channel—voltage, IEPE, bridge—but not always on every channel simultaneously. It’s a matter of how the front-end is configured. When we know your sensor list, we can specify a unit that lets you switch modes channel by channel or assign fixed types to specific channels.

Most loggers stream data to a PC or store it on removable media like SD cards. File size limits depend on the file system (FAT32 caps at 4 GB per file), but ring-buffer recording is common—it overwrites the oldest data when the card fills up. For setups that run for weeks, we look at compression and selective triggering to keep storage manageable.

Units with Ethernet can usually be accessed over a local network, and with port forwarding or a VPN, remote access is doable. Some loggers have optional 4G modules for sites without wired internet. The crucial part is the software stack: we make sure the user interface works smoothly over limited bandwidth, which isn’t always the case with raw data streaming.

We often provide wiring diagrams and grounding guidelines specific to the logger’s input stage. If you’re seeing unexpected noise, common fixes involve checking shield connections, avoiding ground loops, and setting the right input coupling. For larger deployments, we can send a field engineer to verify signal quality on site.
