Critical Technical Advantages
-
Primary Thermowell Protection: The sensors are contained within a heavy-duty primary thermowell. This provides maximum mechanical strength against turbulent flows and abrasive media, while also acting as a primary safety barrier between the process and the environment.
-
Maintenance During Operation: A key advantage of the TMS11 is the ability to replace individual RTD or TC inserts while the plant is running. Because the inserts are housed within the primary thermowell, they can be pulled out and replaced without risk of process leakage or shutdown.
-
Integrity Monitoring: The device features a dedicated pressure port on the process connection. This allows operators to monitor the internal pressure of the primary thermowell. Any pressure increase serves as an immediate diagnostic alert that the primary barrier has been compromised, enabling predictive maintenance before a total failure occurs.
-
High Sensor Density: By utilizing a single process connection (nozzle) to monitor a high number of measuring points along a linear path, the TMS11 significantly reduces the number of vessel penetrations required. This lowers the risk of potential leak points and reduces installation costs.
-
Standardized Sensor Technology: The internal inserts comply with international standards such as IEC 60584, ASTM E230, and IEC 60751. This ensures high accuracy and allows for easy integration into existing control systems and global supply chains for spare parts.
-
Hazardous Area Compliance: The TMS11 is engineered for safety in explosive atmospheres, meeting various protection class requirements (such as Ex d or Ex i) essential for refinery and chemical plant operations.
