Thermowell tip profiles
Tapered
The outside diameter decreases gradually along the immersion length. Used for high velocity applications.
Flat Tip
It one end has flat surface. Used in low pressure applications or where flow characteristics around the thermowell are not important.
Domed Tip
Such thermowell has semi-spherical tip at one end of thermowell. Used in higher pressure applications or where flow characteristics around the thermowell are important. This ensures a high degree of mechanical strength without losing the sensitivity or accuracy of the indicator
Spherical Tip
For spherical tip, special drill is used with a tip angle of 118ÂșC for production of thermowell. To achieve a possible uniform wall thickness, the tip is ball shaped or spherical in shape.
Used in higher pressure applications or where flow characteristics around the thermowell are important. This ensures a high degree of mechanical strength without losing the sensitivity or accuracy of the indicator.
