SS 321 RTD Probe With Thermowell For Harsh Applications – Heatcon Sensors

A SS 321 RTD probe with thermowell is a precision-engineered temperature sensor system designed for high-performance in demanding industrial applications. It includes an RTD probe made from stainless steel 321 and a protective thermowell sensor that shields the probe from physical and chemical stress. The use of SS 321, a titanium-stabilized austenitic stainless steel, ensures high resistance to corrosion and elevated temperatures, making it a reliable choice for continuous, long-term operation in harsh settings.

The main advantage of a SS 321 RTD probe with thermowell lies in its combination of accuracy, resilience, and longevity. It is specifically designed to withstand corrosive environments, pressure surges, and temperature extremes. Unlike thermocouples, which may drift over time, RTD probes offer superior long-term stability and precision. The added thermowell sensor allows for easy replacement and inspection without shutting down the process, thereby reducing operational downtime.

This sensor assembly is widely used in industries such as oil and gas, petrochemical, power generation, marine, pharmaceuticals, and metallurgy. Heatcon Sensors tailors each industrial RTD sensor to match the specific temperature, pressure, and chemical conditions found in different sectors. From refinery pipelines to pharmaceutical reactors, these sensors perform with precision and reliability.

A thermowell sensor serves as a barrier between the RTD probe and the process media. It enhances mechanical strength and prevents contamination, while also allowing sensor maintenance or replacement without system downtime. This is particularly critical in high-pressure and high-temperature industrial applications where process integrity cannot be compromised.

The SS 321 probe is made from stainless steel alloyed with titanium, which offers excellent resistance to intergranular corrosion and oxidation. This makes it suitable for service in environments where temperatures exceed 500°C. The material provides high mechanical strength, formability, and weldability, making it ideal for use in sensors meant for rigorous industrial demands.

Heatcon’s high-temp RTD designs using SS 321 can typically handle temperatures up to 650°C (1202°F). This capability makes them particularly effective in applications involving exhaust stacks, furnaces, reactors, and heated tanks. These sensors maintain accuracy even in continuous high-heat exposure, providing long-term monitoring without degradation.

Heatcon Sensors conducts stringent tests on all harsh environment sensors including vibration testing, thermal cycling, corrosion resistance trials, and IP ingress protection evaluations. The goal is to simulate the worst-case operating conditions so that the sensors can perform flawlessly under real-world stress. These rigorous standards ensure safety and compliance with international norms.
