Mag-Probe Testing Soft Drink Dispenser

These Following Machines and Soft Drink Dispensers are Typically Found in:

The following information will show you how to troubleshoot a set drink dispenser using a Bartol Mag-Probe.

Fast Food and Restaurant Applications

Machine #1 – When a soft drink dispenser selection is made a signal is sent to a solenoid valve causing fluid to fill the cup. The filling time can be controlled by the length of time the button is depressed on the soft drink dispenser or by a signal sent by a timer.If controlled by a timer, the timer controls the amount of time the signal is on. This on time is set to fill the cup and then turn off automatically.

Machine #2 – Most soft drink dispensers have 3-cup sizes, small medium and large and is typically used by employees behind the counter not customers. When the small button on a soft drink dispenser is depressed the length of time is short in order to fill a small cup, a medium cup increases the time, and a large cup timing increases even longer.

Two Problems May Exist If the Cup Is Low or Overflowing:

Soft Drink Dispenser

1. The solenoid set time may be too short or too long.

2. The solenoid valve may have a mechanical problem

By using a Mag-Probe you can test the on/off time of the pulse applied to the solenoid valve coil. By using the timer function on a smart phone in conjunction with the Mag-Probe you can detect the magnetic field around the solenoid valve. If the timing applied to the coil is correct, then you know it is not an electrical problem with the valve. Note: (Fluid must be present to make the test and the equipment must be operational, Safety Permitting). If a magnetic field is not detected then the problem is electrical and will require more electrical testing.

If a magnetic field is detected and the problem still exists there is mechanical problem, and the valve must be replaced.

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.

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, 1963
