Measuring Transducers

  • Programmable AC Voltage Transducers

Measuring transducers are instruments that convert physical quantities—such as temperature, pressure, level, or flow—into standardized, manageable electrical signals (e.g., analog current/voltage) for monitoring, control, and data processing. They incorporate sensors with electronics to provide accurate, isolated, and safe data transmission in industrial, energy, and process control application

Measuring transducers MT 4xx are intended for measuring and monitoring single phase or three-phase electrical power network
