compact, configurable resistance transducers

PT1 is a compact, configurable resistance transducer designed to meet the demanding needs of supply utilities and industrial applications. It provides accurate measurement of resistance values with high efficiency and quick response time. PT1 is equipped with two load-independent, galvanically-isolated analogue outputs that can be configured for different resistance ranges and output curves.


  • Best-in-class response time
  • Site-configurable inputs and outputs
  • Load-independent accuracy on all outputs
  • Diagnostic LEDs
  • Compact footprint
