Mark Lindsey Finds Defective Glue Solenoid Valve

 Mark Lindsey Finds Defective Glue Solenoid Valve In Seconds


Solenoid

Subject:   Re: Thank You

Hi Bob,

Please feel free to use anything I’ve said about the Mag-Probe or paraphrase if needed.     (and, nand, or nor gates etc.) A PLC allows you to make changes to a circuit through software quickly and easily and has input and output that allows modules that allows sensors, Photocells, solenoids, relays, and etc. to interface with it. By the way, I just used a Mag-Probe the other day to prove that a glue vale that was just installed was actually defective. Turning the machine manually revealed 6 quick flashes on the Mag-Probe (impossible to see with a voltmeter) but no glue dots appeared on the label being glued. A second solenoid valve was installed and we were up and running in minutes.

Thanks Again,

Mark Lindsey

Mark Lindsey Writes Back Concerning PLC’s & Pneumatic Valves

Dear Bob,

Sorry that it took so long to get back to you. I had to go out of town and just got back. Thanks for giving me the reports for no charge. Your Mag-Probe is great, I wish I had thought of it. The company I work for has over 150 Electronic Techs on staff and all of us have Mag-Probes provided by the company. They keep some on hand in the stock room because they know some solenoid valves will get broken and placed in a tool bag next to a magnetic screwdriver without the shield on. (I’m Guilty) I use it on Pneumatic valves to quickly determine if a problem is mechanical or electrical without having to take out a meter or access a terminal strip. It’s great for proving to the mechanic that when a cylinder actuates later than it should, that it’s a sluggish valve or cylinder and not an electrical timing issue. Some vales are not safely accessible with the machines running so I just tape the Mag-Probe to the solenoid and watch it through the guard door. Hot glue dot application issues are easy to check also. Showing someone a PLC output might not always convince them but your tool proves that you have got power and a good coil instantly. On top of that you don’t even have to waste time by dragging out prints to see what output to check. Thanks for the free reports and the inspiration that comes from hearing your story.

 

Sincerely,

Mark Lindsey

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
