Benefits of technology
The patent text describes a sensor that can be installed in an HVAC system and remain active for a long period of time without losing its ability to detect condensate or water. This is achieved by designing the circuit to minimize the voltage between the electrodes or pins, which allows the sensor to maintain its performance for up to a week without any degradation. In simple terms, the sensor can detect water for a longer period of time than previous designs.
Problems solved by technology
This induced voltage is high enough to cause significance electrolysis and corrosion damage to the electrodes.

Embodiment Construction
[0021]The present invention relates to a control device including a condensate sensor to generate a control signal when the condensate sensor detects condensate accumulated in a condensate reservoir has reached a predetermined level such as shown in U.S. Pat. No. 8,169,314.
[0022]As shown in FIG. 1, the control device comprises an input section 10 coupled to a control or amplifier section 12 through an AC voltage rectification section 14, an output section 16 coupled through a control signal generator section 18 to the control section 12 and a condensate sensing input section 20 coupled to the control section 12.
[0023]The input section 10 comprises a first terminal 22 coupled to the positive or hot output of the secondary winding of transformer (not shown) and a second terminal 24 coupled to the negative or common output of the secondary winding of the transformer (not shown).
[0024]The AC voltage rectification section 14 comprises a bridge rectifier generally indicated as 26 includin...

A control device including a condensate sensor to generate a control signal when the condensate sensor detects condensate accumulated in a condensate reservoir has reached a predetermined level wherein the condensate sensor comprises a first sensor pin and second sensor pin coupled to a control section by a first detection sensor component and a second detection sensor component respectively balanced to reduce electrolysis that occurs when the condensate reaches the predetermined level that would otherwise cause the first sensor pin and the second sensor pin to corrode excessively.
Description
CROSS-REFERENCE[0001]This application claims priority from pending provisional patent application Ser. No. 61 / 795,455 filed Oct. 17, 2012.BACKGROUND OF THE INVENTION[0002]1. Background of the Invention[0003]A control device for use with a condensate sensor to generate a control signal to activate or deactivate a switch when condensate within a condensate reservoir reaches a predetermined level.[0004]2. Description of the Prior Art[0005]An overflow of condensate / water can cause serious damage to structures such as a home or business if undetected. Numerous devices and systems have been designed to detect water overflow, water leakage or rising water. Generally, when water is detected, a sensor activates a warning device and other devices to reduce or mitigate potential water damage.[0006]A common source of potential water / condensate damage are heating and air conditioning systems. Many such HVAC systems ground the Air Handler and Evaporator to a 24-VAC “Transformer-Ground”. To save o...
