SENS-CUR – Precise current measurement for your energy monitoring
With our SENS-CUR family, you can measure the current in your system with lightning-fast speed and precision—ideal as a plug-and-play solution that integrates seamlessly into your HUB-EN200 system or other measurement systems. Thanks to state-of-the-art, transformer-based measurement technology and an innovative, non-invasive mounting method, you save time and enhance the safety of your systems.
Maximum Safety – Protection Class Category III
For industrial machines and systems, the use of Protection Class Category III sensors is essential. Our SENS-CUR sensors offer:
Enhanced surge resistance:
While Category II devices often withstand only moderate overvoltages (approx. 1.5 kV), our sensors are rated for 3–4 kV or more—ideal for permanently installed systems.
Robust insulation:
Enhanced insulation measures and a rugged housing ensure that your measurement values remain stable even under high loads.
Consistent measurement values:
Optimized temperature compensation and durable components guarantee precise results, even under extreme conditions.
Compared to Category II sensors, which are often less stable under high transient loads and in industrial environments, our sensors offer greater safety and reliability.
Our SENS-CUR sensors are ideal for use in three-phase machines and systems—whether you’re operating a CNC lathe, a machining center, or heavy-duty equipment.
