Current Transducers – T201 Line
T201 Line includes AC/DC current transducers designed to convert measured current value (up to ±600 A) into a 4..20 mA or 0..10 V industrial normalized signal. T201 models, most of them UL certified, are characterized by low power consumption, measuring range freely settable via DIP-switches and high accuracy class avoiding thermal drift. T201 Line is available in 16 models with different measuring principles: average rectified, magnetic balance (patented technology), Hall Effect or TRMS with bipolar input range. “-MU” models include diagnostic, alarm LEDs and an RS485 port supporting Modbus RTU protocol.
Measurement Principles
MAGNETIC INDUTION
The Transducers that use the measurement based on magnetic induction technology are long life devices thanks to the principle of measurement that avoids thermal drifts and which exploits the generation of an induced current on the transducer output, through the variation of a magnetic field. A direct use will be possible without any external shunts, even for pulsed currents.
HALL EFFECT
When a magnetic field is applied perpendicularly to a conductor, a voltage is generated transversally to the direction of the current flow. The Hall Effect Current Transducers are used as alternative to shunt when dealing with high voltages and high galvanic isolation.
