Hi Limit Thermostats & Sensors
Every equipment has a set limit -- and heaters for your pools and spa are not exempted, either. To prevent the meltdown of your heater, high limit sensors are installed. This way, once the temperature for your tub reaches its set point, the sensors will latch open and break the circuit.
Pool and Spa Parts Superstore offers a wide listing of hi-limit thermostats and sensors for your convenience and safety in your pools and spas. There are varying lengths for sensors, and the most commonly used is the 24-inch variant, covering 95% of the market. You can put the heater sensors at each end of your heater for maximum protection.
You can also use a single connector with two sensors at the circuit board. One of the sensors will be for the spa, and the other will be for the heater in the back. You can put the sensor at the cylindrical tube located in the heater.
Other sensors are designed for you to easily slide the temperature probe in the middle of the tub and away from the heater, while the opposing end is connected to the printed circuit board. Check out our product offerings below, ranging from hot tub temperature thermostats, sensors and parts, to spa hi-limit sensors, thermowells, and parts.
