Sensor family aids power measurement accuracy

National Instruments (NI) says it has selected Danisense products as its preferred current measurement sensor family for use with its RM-269994-channel power measurements conditioner. The Danisense DS50UB-10V, DS200UB-10V, DS600UB-10V and DS2000UB-10V current transducers features high accuracy, high bandwidth and low phase shift which are key requirements for accurate power measurement.

NI’s’ RM-26999 is a rack-mounted, signal conditioning device that connects to simultaneous-sampling multifunction I/O devices for power measurements.

It features four voltage input channels with peak voltages up to 2,000 V and four current transducer ports for current measurements.

The current transducer ports are optimised for flux-gate transducers by providing all the power, communication, and signal lines required for accurate measurements.

The RM-26999 can be used with the modular PXI platform, allowing test engineers to synchronise mixed measurements with their power analysis in one unified system.

Engineers can use NI’s RM-26999 Getting Started Guide to select the correct components, safely connect hardware, install the necessary software, and acquire the first measurements in a power measurements system.

“The RM-26999 was designed with Danisense sensors in mind,” according to Sam Burhans, the RM-26999’s Product Manager. “This device measures voltage up to +/-2,000V directly, and measures indirect current up to +/-2000A thanks to the stable, isolated, and accurate Danisense current transducers. We designed the systems for quick connectivity - only a single cable is necessary to connect the RM-26999 to the Danisense transducer.”

NI currently offers four models of Danisense’s isolated current transducers with voltage output. The models offered have measurement ranges of +/- 50A, +/- 200A, +/-600A, and +/-2000A and require a power supply, digital communication, and output signal lines.

Comments Loic Moreau, Sales & Marketing Director, Danisense A/S: “We are excited that National Instruments references and selects our current sense transducers for use with their signal conditioning equipment, and that the guide acknowledges that connection and installation is simple, and that the results are stable and accurate. It is a pleasure to be working with a respected industry-leading company.”
