We understand that in many industries there are overlapping Mag-Probe applications.

In the aircraft industry there are airports, and airports have elevators and escalators that also have relays and solenoid valves that need to be tested.  They also have vehicles with electronic ignition, another application of the Mag-Probe.  The list goes on and on.  By presenting different industry applications in this format users of the Mag-Probe can forward this information to another department and help them to lower their downtime.

The procedures Bob created using the Mag -Probe were specifically designed to reduce downtime. The Mag-Probe enables the technician the ability to separate electrical from mechanical problems in seconds  without using a Schematic, or making contact when testing solenoid valves or relays.

To this day over 100,000 Mag-Probes have been sold world wide and the number continues to grow.    It can detect a magnetic field as low as  3 gauss, as low as 1 gauss with the ring magnet attached.  It can also be de-sensitised for testing larger solenoid valves and relays with overlapping magnetic fields by using the white shield.   It currently is the most sensitive and accurate non-contact magnetic field tester on the market today.


Mag-Probe Applications Oil & Gas

In the gas and oil industry it’s important to observe safety and that is one of the reasons Bob Bartol at Bartol Research initially invented the Mag-Probe.  It is intrinsically safe, can be used underwater, and in the hottest and coldest environments on earth.

Successful Bartol Mag-Probe Drop Test

We hope everybody had a productive year in 2015 and that all is well with you and your families and may God’s Peace rule your lives.   We would like to wish everybody nothing but the best in your work and at home in 2016.

020cdd1We hope this post helps you to better understand the Mag-Probe Applications and it’s versatility.  As the year comes to a close we’d like to tell you how much we appreciate you.   Also, a special thanks to all those hard working men and women that took the time out of their lives to give us feed back on the Mag-Probe.  If you know technicians or engineers in different industries that could benefit by using a Mag-Probe please forward them this post.  Thank you all.

About the Author
Bob Bartol has spent his whole life working with electronics in almost every capacity and spent many hours in Physics classes. He currently holds 4 U.S. patents and has been making a living off one of the patents "The Bartol Mag-Probe" for over twenty years. Bartol Research's Mag-Probe now has a global reach and is dramatically reducing trouble shooting downtime anywhere a solenoid valve. relay, or contactor is used. F111 Air Force Projects - European Flight Competition January 1968 Bob attended electronics school in the Air Force. Upon graduation he was assigned to a fighter wing in Germany. During his assignment he prepared seven aircraft for European competition. The fighter wings aircraft won the competition. Bob then returned to the United States and taught advanced radar for two years. Two years later, he returned to Europe. During this assignment, Air Force headquarters Europe selected Bob to open a Precision Measuring Equipment Laboratory (P.M.E.L) in England. It was the first of its kind in the Air Force. Upon his return to the United States, Air Force headquarters assigned Bob to Air Force research command in Florida. This was strictly a scientific assignment for research and development. After three years he moved from Eglin AFB in Florida to Edwards Air Force Base in California where he had direct contact with the National Bureau of Standards and supported research and development aircraft. During this assignment, he designed a modification for the TF X fighter (F-111). This modification made possible an additional 9800 flying hours per year. The F111 was the first swing wing aircraft in history. General Dynamics completed the modification prior to acceptance by the U.S. Air Force. Modification of F111 Aircraft General Dynamics March 1968 As a result of increasing this flying time Bob Received an award from Edwards Air Force Base for Increasing flying time of the F111 by 9,800 hours per year. The Award was Presented by Colonel Grumbles to TSGT Bob Bartol on June 17, 1968
