UPS4E Handheld Loop Calibrator
Druck’s new UPS4E is a rugged and extremely compact loop calibrator, designed to be operated
with one hand. Small enough to fit in the top pocked of an overall, the UPS4E is the latest
addition to the Druck “UPS” series, following on from the much-loved UPS-II and UPS-III.
Replacing the legacy UPS-III (and UPS-II) loop calibrator, the UPS4E is a modern,
cost-effective device that is available on competitive lead times.
The UPS4E is a handheld device used to test and calibrate current loops in industrial control systems. It can source, measure, or simulate a precise electrical current—typically in the 4–20 mA range—allowing technicians to verify the performance of sensors, transmitters, and control systems. It also provides 24V loop power, making it an essential tool for troubleshooting and maintenance in process automation environments.
Incorporating feedback from instrumentation technicians, maintenance engineers and automation professionals, the UPS4E represents the pinnacle of loop calibrator performance.
