Current Sensing
-
voltage-output, current-sensing amplifier family that integrates an internal shunt resistor to enable high-accuracy current measurements at common-mode voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device is a bidirectional, low- or high-side current-shunt monitor that allows an external reference to be used to measure current flowing in both directions through the internal current-sensing resistor sensor. The integration of the precision current-sensing resistor provides calibration equivalent measurement accuracy with ultra-low temperature drift performance and ensures an optimized Kelvin layout for the sensing resistor is always obtained.

Stand-Alone Doppler Current Sensor
DCPS
-
The Doppler Current Profiler Sensor (DCPS) is a medium-range, 600kHz current profiler smart sensor. It offers high-quality ocean current measurements and is ideally suited for cabling directly to various systems or dataloggers via serial or AiCap bus. With its integrated compensation for tilting and movement, the sensor is commonly used to measure current from buoys and other moving platforms.The 5400/5400R version of the current sensor is 300m depth rated, the 5402/5402R version is 4500m depth rated, and the 5403/5403R version is 6000m depth rated and intended for commercial as well as research use. It comes with an integrated temperature sensor that can be calibrated on request.As an extension to the DCPS, we now offer the current profiler with an integrated pressure unit called the 5400P. This version enables acoustic wave measurements in addition to profiling currents. Ideal for small observatories, the DCPS sensor is the market's lowest-cost current and wave sensor.

Single-Phase Transformer Winding Resistance Meters
RMO-TT Series
-
RMO-TT series is perfect for measuring winding resistance of inductive objects such as power and distribution transformers or autotransformers. Additionally, every transformer resistance meter from RMO-TT series can analyze:tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.Transformer demagnetization can also be performed with all RMO-TT instruments.The series is consisted of 3 models, with maximal test current from 40 A (RMO40TT) to 100 A (RMO100TT). RMO100TT is the only portable transformer resistance meter in the market with 100 A DC output current.The three independent channels enable testing of three windings in series. Consequently, a user can measure winding resistance in every tap position of an on-load tap changer without discharging between the tests.In addition to winding resistance measurement, a user can perform a detailed on-load tap changer analysis by analyzing recorded graphs (10 kHz sampling rate) and by measuring vibrations on an external tap changer tank.All RMO-TT instruments have a built-in tap changer control unit. Because of this, it is possible to remotely control on-load tap changer (OLTC) directly from the device. Also, a user can program DV-Win software to do everything automatically – running winding resistance tests and changing OLTC tap positions.The DV-Win software also enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test.All results can be exported in the report format.
