Description

The Druck UPS-II loop calibrator is an advanced handheld process calibrator tool. The Druck UPS-II loop calibrator can power (24 VDC) and read 2-wire transmitters to perform field calibrations. Output currents are adjustable to a resolution of 10 microamps in both source and transmitter simulation modes.

Fixed Steps

The Druck UPS-II loop calibrator can source or stimulate fixed calibration currents to test or calibrate receivers and to stroke valves. Different current levels are available from the menu.

  • 4-20mA Linear: 4 - 8 - 12 - 16 - 20mA
  • 0-20mA Linear: 0 - 5 - 10 - 15 - 20mA
  • 4-20mA sq.rt (Flow): 4 - 5 - 8 - 13 - 20mA
  • 0-20mA sq.rt: 0 - 1.25 - 5 - 11.25 - 20mA
  • 4-20mA: 3.8 - 4 - 4.2 - 12 - 19 - 20 - 21mA

The Druck UPS-II loop calibrator's output currents can be changed manually or automatically. The time between steps is 10 seconds in the auto-stepping mode. In the valve mode, auto-stepping will be 3.8 - 4 – 4.2 or 19 - 20 - 21mA.

Ramping

The Druck UPS-II loop calibrator can source or simulate with high resolution a continuous up / down cycle between 4 and 20mA or 0 and 20mA. The travel time between limits is 60 seconds.

Reading in Percentage

The Druck UPS-II loop calibrator can display readings in percentage of a 4-20mA or 0-20mA span and can also read or simulate dP-transmitters directly in percentage of flow.

The standard instrument kit provided with the Druck UPS-II loop calibrator includes carrying case, alkaline batteries, set of test leads, users guide, and calibration certificate.

An intrinsically safe version of the Druck UPS-II loop calibrator is available.
