Patented Temperature Comparison Circuit Device for Monitoring Heating and Cooling Systems:  U.S. Patent # 6,101,827

The Temperature Comparison Circuit Device monitors central heating and cooling systems, freezers or coolers constantly, eliminating any problems before they cause damage. It is available for license. 

Shown Below:   A temperature comparison circuit with expansion valve:

Temperature Comparison Circuit Device:  

Detects the following problems: 

• Dirty air filters
• Leaky ducts
• Blocked ducts
• Defective fans
• Blocked coils
• Defective burners

Applications:

• Furnaces -- to automatically control the air ducts
• Air conditioners -- to monitor AC efficiency
• Freezers -- to detect frost level for food storage
• Wheel bearings:  Sometimes the wheel bearing on a vehicle becomes defective, and as the bearing becomes more defective over time, the level of friction increases and the heat level starts to rise.  The Temperature Comparison Circuit Device allows the friction level of the 2 bearings to be compared, by placing a sensor on each of the 2 wheel housings.
• Laboratories -- to monitor conditions 
• Chillers
• Cold storage

Shown Below:   A temperature comparison circuit and valve controls bath water temperature:
