Critical Technical Advantages
-
Vibration-Resistant Technology (iTHERM StrongSens): The TM111 can be equipped with StrongSens technology, providing unsurpassed vibration resistance of over 60g. This is critical for maintaining measurement integrity and plant safety in applications near pumps, compressors, or high-flow pipelines.
-
Rapid Response (iTHERM QuickSens): For processes requiring tight control, the QuickSens insert offers an industry-leading response time of just 1.5 seconds. This allows for near-instantaneous detection of temperature fluctuations, optimizing process efficiency.
-
Automated Insert Production: iTHERM inserts are manufactured via a globally unique, fully automated process. This ensures full traceability and a consistently high level of product quality, leading to long-term stable and reliable measured values.
-
Optimized Maintenance and Handling: The variety of TA30x terminal heads available for the TM111 simplifies installation and maintenance. When paired with an optional iTEMP transmitter, the device supports Bluetooth connectivity, allowing technicians to verify measured values and configurations from a safe distance without opening the housing.
-
Broad Communication Support: The integrated transmitter options support all common industrial protocols, including 4-20 mA, HART, PROFIBUS PA, and FOUNDATION Fieldbus, ensuring seamless integration into any control system architecture.
-
Comprehensive Hazardous Area Approvals: With international certifications including ATEX, IECEx, CSA C/US, and NEPSI, the TM111 is ready for global deployment in explosive gas and dust atmospheres.
