Purpose and use of different types of measuring
transducers
1.3.1
Programmable AC Voltage transducer MT416
MT416 is intended for measuring and monitoring single-phase voltage or frequency. Voltage input is
electrically insulated from the system by means of voltage transformer. It measures TRMS voltage value
by means of fast sampling of voltage signals, which makes instruments suitable for acquisition of
transient events. A built-in microcontroller calculates measurands (voltage, frequency) from the
measured signals. Measurands can be then converted into load independent DC current or voltage
which is proportional to the TRMS measured value for the purpose of regulation of analogue and/or
digital devices.
1.3.2
Programmable AC Current transducer MT418
MT418 is intended for measuring and monitoring single-phase current or frequency. Input current is
electrically insulated from the system by means of current transformer. MT418 measures TRMS current
value by means of fast sampling of current signals, which makes instruments suitable for acquisition of
transient events. A built-in microcontroller calculates measurands (current, frequency) from the
measured signals. Measurands can be then converted into load independent DC current or voltage
which is proportional to the TRMS measured value for the purpose of regulation of analogue and/or
digital devices.
