The Carel 10,000-ohm water sensor features a 2-wire design and comes in various lengths, including a 10-foot option. Its stainless steel tip measures 2 inches long by 1/4 inch in diameter. This sensor is widely used in most chiller systems and is a must-have spare for technicians and boat owners alike. Known for its reliability, the 10-foot version replaces Condaria models 5330250 and 5331030, as well as Dometic models 222103012 and 4471003282. The 20-foot version substitutes for Dometic 222103013 and 4471003283. To confirm compatibility, measure the sensor’s resistance at 72°F; a reading near 10,000 ohms indicates the correct sensor, while around 3,000 ohms suggests otherwise.
