Thermowells are protective fittings designed to house and safeguard temperature sensors such as RTDs, thermocouples, and temperature gauges from direct exposure to process media. They allow temperature instruments to be installed, removed, or replaced without interrupting the process flow or shutting down the system.

Manufactured from high-quality stainless steel, thermowells protect sensors against high pressure, high temperature, corrosive fluids, vibration, and mechanical stress, ensuring longer sensor life and reliable temperature measurement.

Thermowells are widely used in food, dairy, beverage, pharmaceutical, chemical, oil & gas, power, and general industrial applications.
