Compact, configurable multiple measurand transducers

PT1 is a range of compact, configurable multiple-input transducers designed to meet the demanding needs of supply utilities and industrial applications. It offers accurate true-RMS measurements and quick response time. It is equipped with two load-independent, galvanically-isolated analogue outputs that can be configured on site for different input parameters, input range and output curves.

Features

  • Best in class response time
  • Long range, site-configurable inputs, outputs and measurands
  • Load-independent accuracy on all outputs
  • 2-in-1 programmable transducers
  • Diagnostic LEDsŸCompact footprint
