A thermowell is a cylindrical connection that is installed to protect a temperature sensor, one end of which is closed and the other end is open. The closed end is placed in the process and the temperature sensor, which is a thermocouple or resistance sensor or thermometer, is inside the open end. Temperature sensors are usually mounted on the thermowell by a spring to ensure that the sensor is connected to the thermowell. The open end of the thermowell is usually located in the open air outside the process piping, and in the event of a sensor failure, it can be easily replaced without emptying the tank or tube.
