UPS-III

What does the UPS III loop calibrator do?

Are you looking for a small and handy loop calibrator? The UPS III from GE, also known as the 'Unomat' is originally a Dutch manufacture. In the process industry it is one of the most used measuring instruments in addition to the multimeter. The instrument is suitable for testing and calibrating electrical circuits, measuring and simulating milliampere signals and measuring volt signals. This loop calibrator is also available in an ATEX version. The UPS III has a range of 0-24 mA at 21 V and 0-50 V DC. The instrument is also equipped with a 24V power supply for instruments.

Application

The UPS III has an accuracy of 0.015% of the verified value including temperature effects and a stability over 12 months. This makes this calibrator about ten times more stable than the average multimeter. With the built-in 250 Ω resistor, the UPS III can be used for testing Hart transmitters. This is an essential tool for testing loops, switches, instrument maintenance and setting valves. The instrument is small, robust and easy to use. The loop calibrator comes with a calibration certificate.
