Product Description
The Druck UPS4E loop calibrator is a rugged and extremely compact loop calibrator, designed to be operated with one hand. Small enough to fit in the top pocket of an overall, the UPS4E is the latest addition to the Druck "UPS" series, replacing the legacy UPS-II and UPS-III loop calibrators.
The UPS4E is an essential tool for testing and calibrating 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.
The calibrator has an easy-to-read display and simple-to-use time saving features including step, span, and valve check. Accuracy is 0.01% of reading plus 1 count over the full 0-24mA range. The built-in 250Ω resistor supports HART operation. Data logging capability stores 100,000 points for later analysis.
