Abstract: A device for measuring the temperature of the water inside a water container. A temperature probe that defines a front end and a rear end has its front end exposed to water inside the water container. A temperature probe mount mounts the temperature probe to the side of the water container and allows access of the front end of the temperature probe to the water inside the water container. A temperature probe insulator fits over the rear end of the temperature probe. The temperature probe insulator attaches to the temperature probe mount and prevents rearward motion of the temperature probe. In a preferred embodiment, the water container is a spa. In a preferred embodiment, the temperature probe insulator is made of a rubbery substance.
Abstract: A dry fire protection system for a spa and the spa's associated equipment. A heating element heats the spa's water. A resistive water level sensor senses that the level of water around the heating element is higher than a predetermined height or lower than a predetermined height, and a heating element deactivation device electrically deactivates the heating element when the water level around the heating element falls below a predetermined level. In a preferred embodiment, the heating element deactivation device is an electric circuit comprising a comparator circuit and a control circuit.
