GE's UPS-II loop calibrator is an advanced handheld process calibrator tool. It 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.
Fixed Steps
The GE 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 to 20 mA linear 4, 8, 12, 16, 20 mA
- 0 to 20 mA linear 0, 5, 10, 15, 20 mA
- 4 to 20 mA sq.rt (flow) 4, 5, 8, 13, 20 mA
- 0 to 20 mA sq.rt (flow) 0, 1.25, 5, 11.25, 20 mA
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, 21 mA
Ramping
The calibrator can source or simulate with high resolution a continuous up/down cycle between 4 and 20 mA or 0 and 20 mA. The travel time between limits is 60 seconds.
Reading in Percentage
The calibrator can display readings in percentage of a 4 to 20 mA or 0 to 20 mA span and can also read or simulate dP-transmitters directly in percentage of flow.
