Company: Danisense A/S
Category: Test, Measurement & Inspection Product of the Year
Danisense A/S was founded in 2012 and is based in Denmark and Japan. The company’s founders and key employees are highly experienced and possess specialized knowledge about high precision current transducers, enabling Danisense to create solutions that enable its customers to quickly and easily measure AC and DC currents with very fine accuracies down to 1ppm. Danisense combines complex magnetic performance with advanced electronics to provide efficient and precise solutions that match the requirements of worldwide customers in demanding industries. Its products are of the highest quality and have an extremely flat frequency response and outstanding DC stability.
Danisense’s ultra-stable, high-precision DP series of PCB-mount current transducers measure isolated DC and AC current up to 72A. Extremely compact and lightweight, the DP Series features class-leading high stability and accuracy in a footprint of only 64.9 x 60mm, a height of 32mm and weight of 250g. This compact device is suitable for 1U power supplies and other space-constrained applications and its small size and low weight make it possible to include such high-performance measurement functionality on a PCB for the first time.
The DP Series features Danisense’s closed-loop, compensated Fluxgate technology, which provides a fixed excitation frequency and second harmonic zero flux detection. Delivering best-in-class accuracy and stability, DP series PCB-mount current transducers feature a maximum linearity error of 10 ppm and a measurement resistance of up to 100â„¦ at full scale. Devices are programmable for 12,5A, 25A, or 50A usage via the PCB layout.
Applications for the DP Series include MPS for particle accelerators, stable power supplies, precision drives, battery-testing and evaluation systems, power measurement and power analysis.
With regard to applications in particle accelerators, it is notable that Danisense current transducers have been used by teams at CERN as part of a significant upgrade program. The Danisense zero-flux DC current transducers (DCCT) are used in the design of QTRIM power supplies for the PS booster accelerator which are part of a chain of accelerators that inject the beam into the LHC (Large Hadron Collider) at the European Laboratory for Particle Physics.
Despite the challenging conditions of the COVID-19 crisis, in March 2021, Danisense announced growth of nearly 10% over the previous year.
