Description

Transmille offers a set of current shunts which enable measurement of current from 1mA  to 100A. Each shunt develops 0.7V at nominal full scale, enabling a wide range of multimeters to be used without loss of resolution due to changing range.

High Performance Design

Transmille’s AC/DC current shunts provide excellent DC value stability, but also a wide range in frequency allowing measurements from DC up to and beyond 30kHz. The coaxial design of these shunts reduces inductive and capacitive effects, while an open design improves heat dissipation to minimize power co-efficients. The coaxial design offers superior accuracy and low electromagnet influences, ensuring a linear and predictable frequency response. Each shunt has a type N output connector to ensure low noise when measuring at high frequencies, providing easy connections from the shunt to the measuring device.

The set of AC/DC current shunts has been designed to enable fast and efficient calibration of multiproduct calibrators and current sources under a laboratory environment. Using the AC/DC current shunts in conjunction with an 8000 series multimeter, the 3000A, 4000 and 9000A multiproduct calibrators can be efficiently maintained internally, as well as supporting other manufacturers’ products.

  • AC/DC differences from 1PPM
  • Superior accuracy compared to Wilkinson standard AC/DC resistors, minimizing the use of correction factors for frequency response
  • Shunt values for measurements between 1mA to 100A
  • From DC to 30kHz
  • Low inductance & capacitance flat frequency response
  • Simplifies precision calibration of calibrators and current sources
  • Can be used with a precision multimeter, or an AC measurement standard

Transmille offers a total of 14 high-precision shunts, each with an output value of 0.7V against nominal input. These shunts come in various input values, from 1mA  to 100A*.

Current shunts can be supplied with certified AC/DC corrections from NPL for traceability directly to international standards.

An optional connections kit is also available to enable fast connections to typical test equipment.
