Outline / Applications / FeaturesClosed Loop Hall Effect Technology Electrohms current sensors based on closed loop Hall effect technology measure direct, alternating and pulse currents with galvanic insulation between the primary and secondary circuits. A magnetic flux created by the primary current IP is nulled by driving a current through the secondary windings and creating a complementary flux. A hall element placed in the air gap of the magnetic circuit along with additional circuitry produces a compensating current in the secondary winding that propotionally replicates the primary...

Outline / Applications / FeaturesOpen loop Hall effect technology Key factors affecting the bandwidth performance are core geometry, number and thickness of the laminations, type of core material and circuitry used. In some of our designs we use the latest generation of ASICs which has substantially improved bandwidth performance. Principle Electrohms current sensors based on open loop Hall effect technology measure of direct, alternating and impulse currents, with galvanic isolation between the primary and secondary circuits The primary current lp flowing in the sensor creates a...

Outline / Applications / FeaturesClosed Loop Voltage Transducers (C/L)l L._J The input voltage is dropped across a voltage divider and very small current limited by a series resistor is driven through the primary of a coil. A magnetic flux created by the primary current is nulled by driving a current through the secondary windings and creating a compensating flux. A hall element placed in the air gap of the magnetic circuit along with additional circuitry produces a compensating current in the secondary winding that propotionally replicates the primary current which is an exact...

Outline / Applications / Features Optical Voltage Transducers The measured voltage, VP, is applied directly to the sensors primary connections through a resistor network followed by signal conditioning circuitry into a high isolation, precision optical amplifier stage. The isolated output is amplified through a precision linear circuit producing an output signal which is completely isolated from the primary and is an exact representation of the input voltage. The power conditioning circuits feeding the optical stage is designed with an even higher isolation to the signal circuitry to ensure...
