Gauss meter kit

Gauss meter kit

Build your own Gaussmeter. Have you ever wanted to find out how strong a magnet really was, or how the strength of the magnetic field varied as you changed the distance from the magnet or the temperature of the magnet, or how well a shield placed in front of the magnet worked?

Voltmeters are fairly inexpensive and easy to find, but where do you purchase a Gaussmeter also known as a magnetometer. I built a hand-held Gaussmeter for measuring the polarity and strength of a magnetic field. It uses a linear Hall effect device and some op-amps and resistors and things from Radio Shack.

Then I will describe a Gaussmeter with a few more bells and whistles. An inexpensive Hall effect Gaussmeter. You can get them most anywhere.

Next is a battery clip to connect to the top of the battery. To purchase the uncalibrated Hall device, go to Hall Effect Devices. You will need something to mount these parts onto - there are two possibilities. Use an inexpensive perf board and solder the parts to it, or use the breadboard and just plug the parts in - no soldering! Unless you've built electronic things before, I would recommend the breadboard since it is easy to use, easy to change, and can be used for other projects in the future.

You need a voltmeter for all the projects you're going to work on anyway, so I won't add that in for this project. There are different types available, and their cost goes up with features and functions. A basic one that will work well is noted in the table above. Battery and voltmeter not included. Now, how do you make it? Connect the - black of the battery clip to the common of the pin 2.

Connect the common of the Hall device pin 2 to the common of the pin 2. Set the voltmeter to read 20Vdc max. Attach the - of the voltmeter to the common of the pin 2 or the common of the Hall device pin 2. You are now ready to snap a battery onto the battery clip. Here's a schematic of the circuit using the or A Hall-Effect Device :. With no magnet near the Hall device, measure and note the output voltage reading. Call this V0. It should be about 2.

Now, with a magnet near the Hall device, you will see the output voltage change. If it is a South pole, the voltage will increase. If it is a North pole, the voltage will decrease. Call this voltage reading V1. We will say that the sensitivity of the Hall device is 2. Call this k.With that understanding, the absolute best tool you can arm yourself with is a quality EMF meter, that is accurate, simple to use, and measures all types of EMF radiation.

Each of the following EMF meters was chosen based off of a variety of factors, including but not limited to:. For example, the Trifield TF2 is my number one recommendation but is much more affordable than, for example, the Acoustimeter AM Although the Acoustimeter is a fantastic device, I believe the Trifield delivers a fantastic product at less than half the price.

These rankings are therefore a cumulation of all of the factors bulleted above. With that in mind, this list, although thoroughly researched and designed, is open to interpretation. I was not gifted any of the devices I review in this article, nor have I communicated with any of the companies. My rankings and reviews are based entirely on my own use of the products, experience, research, and opinion.

See the Amazon listing here. The best place to get the Trifield TF2 is on Amazon. Feel free to take a minute and read through some of the 5 star reviews. The price is extremely reasonable, and you honestly will love how accurate and simple to operate this device is. Check out the Amazon listing here. It is extremely accurate, simple to use, and preferred by professionals. However it does have its downsides, for example, it only reads RF radiation, and is not designed to read electric field or magnetic field radiation.

There is a reason that you will see the Acoustimeter AM in the hands of so many professionals, it is extremely accurate and simple to use. Sensitivity — To start with, the Acoustimeter is one of the most sensitive RF meters on the market, capable of reading even the smallest amounts, of the lowest radio frequencies and displaying them.

Not only that, but it also has fantastic directional sensitivity. This will allow you to easily locate the direction that the largest RF radiation sources are coming from by simply moving your Acoustimeter in a circle and watching the display to see peak readings. I have a great guide on how to see a map of every cell tower near your home. Frequency Range — The next thing I really like about the Acoustimeter is its enormous frequency range that it is able to measure.

For example, the Trifield TF2 is capable of reading up to 6Ghz which for now is probably plenty whereas the Acoustimeter can read all the way up to 8Ghz, giving you a wider range that you are able to measure.

Ease Of Use — Next, the Acoustimeter is really simple to use. There is a simple display at the top, as well as two rows of LED lights below.

DIY Gauss Meter with Dual Sensors for Measuring the Strength of Magnets

When using the meter, I personally like to plug in a pair of headphones into the audio jack with or without the headphones and use the audio to help me locate sources of RF radiation. If you take a look at the small screen to the right, you can see what will typically be displayed.

Here is how you would read this screen:. Cost — First of all, it is a fairly expensive device relative to its features. At more than double the price of the TF2 at the time of this writingyou certainly want to make sure this is the device for you before purchasing. Just understand that you are paying for the accuracy and quality of the machine, not for bloated features.It is fast and intuitive to use, with an extremely high dynamic range, measuring from 0.

Above Gauss the range automatically changes, reading Therefore a change as small as 0. This Gauss meter also measures AC field up to 10, Gauss. A fast peak hold function 2-millisecond window captures and displays any transients, whether positive or negative.

In addition, either of two fast 2 milliseconds alarm functions can be selected when required. The alarm can sound either when the field exceeds a value that you set, or if the field is ever between two values you set. Immediately displays the DC or AC magnetic field.

Can be rapidly scanned across a part to check magnetization. An alarm sounds only where the field magnitude exceeds the level that you set or where the field is between two levels you set. The alarm response time is 2 milliseconds, so it can be scanned quickly. The alarm can be used either to check for any residual magnetism or to sound if a magnet is out-of-spec by setting the upper level just below the minimum acceptable field.

The peak displayed includes the polarity sign, and the value will be held in memory until you reset it or turn off the meter. Offset, if required, is manually adjustable. Several interchangeable probe types are available, and the meter automatically detects the probe type. With the HS-Probe, parts can be rapidly scanned for residual magnetism. An alarm can be set to sound is any region exceeds a set threshold.

Using the AC adapter, the meter can be left on permanently to capture the peak field value if at least 0. Above 20kG, it is 0. There are two series of probes: ST standard; 0. Each series is available in three shapes: universal, axial, and transverse.

The universal can be bent thousands of times if needed between an axial shape which measures the field component parallel to the cable direction and a transverse shape which measures the component parallel to the thin dimension of the probe. Each probe is at the end of a cm flexible cable. How can we help? Call Now: 1.
