UMT 1 Series

Woodward Measuring Transducers with RMS Sensing

Woodward’s UMT 1 Series consists of measuring transducers that feature true RMS sensing. Measured values are calculated and displayed on a two-line, 16-character LC Display. They can either be assigned to analog outputs (configurable as -20 to 20 mA, 0 to 20 mA, or 4 to 20 mA) or transmitted to a higher-level control system via RS-485 or Profibus DP interface.

The primary measured values of voltage and current are used to calculate the values for active, re-active, apparent power, power factor (cosphi), kWh and kvarh. An impulse output is also provided to output kWh or kVarh values.

Features include:

  • True RMS sensing
  • Class 0.5 accuracy
  • RS-485 Modbus RTU Slave or Profibus DP communication
  • Configurable measuring system for either single-phase, three-phase, or a combination of both
  • Front panel configurable
