Thermowells For Aid in Temperature Sensing by Duda Energy A thermowell is needed in order to use a temperature sensor in a tank or pipe system. These are usually pre-installed inside of a solar tank however they may be installed into any port or pipe fititng which has 1/2 NPT fittings. In pipe installations use a tee for connecting to pipes. The sensor slides inside of the thermowell once secured into a pipeline or tank. This may also be used as a replacement for corroded thermowells pre-installed into Duda Solar tanks. It may also be used for other temperature sensing applications such as biodiesel processors and other fluid heating applications. Use the copper thermowell for fast temperature detection. Stainless steel options are also available for better rigidity and where chemical resistance may be required such as in biodiesel applications. Inner diameter of the tube inside the thermowell for insertion of the sensor is approximately 7mm. These are best used with the Duda Energy pt1000 and 10k sensors. Longer length thermowells allow for deeper insertion into a tank or pipeline. These may be beneficial when it is a large tank or the sensing needs to be in the center of a pipeline. Copper thermowells have brass 1/2 Hex Adapters. Stainless steel thermowells have stainless steel 1/2 Hex Adapters
