Shielded Leach Relays on Boeing Aircraft

Leach Relays Play an Essential Part in Keeping a Plane Up and Running

This post talks about the Bartol Mag-Probe Making quick tests on Boeing Aircraft Leach Relays

The Bartol Mag-Probe is Used in Aircraft Maintenance to Check the Coils of Electro-Mechanical Relays.  In order to Create a Magnetic Field around an Electro-Mechanical Relay Coil, Current, Continuity and Voltage Must be Present.  The Mag-Probe can Detect a Magnetic Field as 
low as 1 Gauss on any Shielded Electro-Mechanical Relay without having to remove it from the socket on any Aircraft Panel.

Leach relays

Relays play an essential part in keeping a plane up and running in spite of internal damage. It functions as a switch that controls the currents. It will keep the circuit running even if one portion experiences problems or shuts completely. This is extremely important in keeping your plane from crashing if you have any problems midair. You need to decide on a relay which is efficient in switching circuits. It should have also an automatic fuse which will activate at the slightest indication of a problem.  Airplanes use hermetically-sealed units just like Leach relays, which drive away pollutants and other contaminants. These Leach relays are also able to withstand extreme temperatures, in addition to excessive vibration and shock. Check the amount of amps a unit can handle and whether that is appropriate for your aircraft system. It’s also wise to look at the sockets inside your board to know the number of pins your relay needs to have. Leach products also have corrosion-resistant metal canisters.


This means that it will last for many years.  Read More . . . .

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
