   The Model 460 3-channel Hall effect gaussmeter is the best choice for applications requiring 3-axis measurements or 3 simultaneous single axis measurements. The Model 460 combines the performance of 3 Model 450 gaussmeters into one package, making it an excellent value for materials analysis and field mapping applications. The large vacuum fluorescent display shows readings for all 3 channels simultaneously as well as vector magnitude or differential readings. The full-function keypad provides easy access to measurement features.

Features

  • Can be operated with 3 individual probes, a single 2-axis probe and 1 individual probe, or a single 3-axis probe
  • Displays each axis simultaneously
  • Vector magnitude reading
  • Resolution to 5¾ digits (1 part out of ±300,000)
  • Accuracy to ±0.10% of reading
  • Peak capture
  • Analog voltage outputs
  • IEEE-488 and serial interface
  • Range and Resolution

       When used with appropriate probes, the Model 460 3-channel gaussmeter offers full scale ranges from 300 mG to 300 kG. A different range can be used with each input. With 5¾ digit resolution, DC field variations approaching 0.010 mG can be detected; in larger DC fields, resolution to one part in 300,000 is possible. For RMS and peak measurement, resolution is 4¾ digits or one part in 30,000 because environmental noise is more difficult to separate from the desired signal in those modes. The filter feature of the Model 460 improves resolution in noisy environments by taking a running average of field readings. DC mode requires filtering to achieve 5¾ digit resolution.

    Measurement Features

       The Model 460 operates in DC, RMS, and Peak modes, with superior accuracy and resolution in DC measurement mode. Measurements to 5¾ digits are possible due to the low noise floor. With low noise and high stability, the Model 460 is ideal for multiple axis field mapping applications. Changing fields that are often used in material analysis systems can be measured on all 3 inputs up to 18 times per second over the computer interface, with excellent resolution. Best suited for fringe field measurements or measurement of magnets and solenoids driven at line frequency, RMS mode measures periodic AC fields from 10 Hz to 400 Hz. Instrument circuitry accommodates wave forms with crest factors up to 7, with true RMS conversion. Peak circuitry in the Model 460 captures single event peaks or monitors the peak amplitude of periodic wave forms from 10 Hz to 400 Hz, with reproducible single peak measurements down to 5 ms rise time. Instrument software accommodates indefinite hold time with no decay.
