      Description

      This current transmitter has been designed using a dedicated, precision, true RMS to DC converter in combination with the most recent, low-cost, powerful microprocessor. This enables us to offer flexibility, reliability and accuracy at a good price in a small package.

      Included in the design is a full wave rectifier and zero crossing detector. These provide for current measurement on a ‘per cycle basis’ for high speed applications and also accurate frequency measurement.
