Displays X,Y,Z and magnitude of magnetic field, for rapid mapping and measurement of magnetized materials. Range is 799.99 gauss.
Product Description:
The Vector Gaussmeter displays the true magnitude of the field at any location as well as the X, Y, Z components of up to 800 gauss. Also separately displays peak values of X, Y, Z, and magnitude. There is a sound alarm that determines the locations where the field magnitude exceeds user-set threshold. Because magnitude is measured, the orientation of the sensor (E-W, N-S, and up-down) is not important; this is unlike a 1-axis gaussmeter. With the VGM the user can set the alarm to 15 gauss (for example) and it will sound (simultaneous with a red light) whenever the field exceeds 15 gauss for at least 5 milliseconds. Using the meter this way, it is easy to make a map of the 15 gauss line (or for whatever threshold is set) around a strong magnet. When using the alarm, of a steel part can be rapidly scanned to show if any areas exceed the set threshold. Then the “peak hold” function can be interrogated, showing the peak values of X, Y, Z (including polarity) and magnitude that occurred during the scan. Peak hold also has a 5 millisecond response time. The “reset” button resets all peak hold registers to the present values of X, Y, Z and magnitude, which are displayed in real time when the knob is set to “measure.” Offsets can be manually applied to X, Y, and Z, or a “relative zero” can be applied to all three. This subtracts out the field at the time the button was pressed.
VGM Output Jack Description:
An alarm output jack is on the side of the VGM. Included is a plug terminating two wires, which is a 1/8" (3.25 mm) phone jack, similar to a small headphone jack. Output is 3.5 V when the alarm sounds (but only if the alarm is active) and 0V when the alarm is not sounding.
Features
- Displays the magnitude of magnetic field regardless of probe orientation. Also can display X, Y, or Z components.
- When set to “Peak Hold”, displays the highest magnitude since the last time “Reset” was pressed. Also remembers and can display peak value of X, Y, Z (including polarity) since the last "Reset."
- Continuous sampling and magnitude calculation every 5 milliseconds; the peak of X, Y, Z and magnitude will be accurate even if they occurred at different times.
- Sound alarm and light for rapid feedback if the field exceeds threshold you set.
- Relative zero and manual offset functions independently for X, Y, Z.
- Includes battery, AC Adapter, alarm output (open/closed switch)
- CE Compliant.
Application:
- Very fast screening of parts for residual magnetism. By using the alarm and peak hold functions, partially magnetized parts can be characterized with a minimum of effort, regardless of whether the field is oriented in an unexpected direction.
- Rapid mapping of magnetic field, such as from an MRI. Use the alarm functions, for example, to find the 5 gauss contour without worrying about the probe orientation.
- Use as a laboratory X, Y, Z and magnitude magnetometer. Also measures transient field, even if a pulse occurs once for 5 milliseconds within a period of days.
