Main features High sensitivity Low noise, near the theoretically lowest possible level Frequency band 10 Hz - 600 kHz Super-light construction Low power consumption Metrological certification

New calculation methodology using minimal mass criteria allowed to minimize the weight, conserving necessary length in order to provide low noise level in wide frequency band. The magnetic feedback design is utilized what provides a stable response over several decades of frequency. Over the flat band region the sensor operates as a B field detector; for the frequencies below the flat part the sensor response is proportional to signal frequency or to dB/dt derivative. Low noise preamplifier is placed inside the sensor.
