BBM-3D

BBM Broadband AC Magnetometer

The BBM-3D is a wide band, high sensitivity general purpose AC magnetometer designed for precision measurements of AC magnetic fields generated by power lines, substations, transformers, motors, CRT's, industrial equipment and any electrical appliance. It identifies and monitors radiation levels from virtually any source.

The BBM-3D incorporates a high grade filtered induction coil sensor that eliminates error caused by sensor movement within the earth's magnetic field. This quality instrument provides reading accuracy of 1% with a precision of 0.01 milligauss.

Two analog output connections are provided for those applications where a LCD readout is not sufficient. The RMS value is available for connection to a strip chart recorder or DAS. A wideband connection (12 Hz to 50 kHz) provides a signal for an oscilloscope, waveform recorder, DAS or spectrum analyzer.

The superior sensitivity, accuracy, wideband performance, and convenience of use in power line and appliance field measurements make the BBM-3D the instrument of choice for extremely low, AC magnetic field measurement.
