重要な技術的利点
-
High-Pressure Barstock Design: Specifically built to withstand immense process pressures up to 500 bar. The barstock thermowell provides a massive mechanical barrier, making it suitable for high-velocity steam or high-pressure hydrocarbon flows.
-
Dual Seal Technology: This features a secondary process seal that acts as a backup barrier. In the event of a primary thermowell breach, the Dual Seal prevents process media from escaping into the terminal head and provides a failure indication, allowing for proactive maintenance and enhanced plant safety.
-
Simplified Maintenance (iTHERM QuickNeck): The TM152 features the divisible QuickNeck, which allows the upper part of the thermometer to be removed for recalibration without tools. This can be done without interrupting the process or disconnecting wiring, significantly reducing maintenance costs and downtime.
-
Extreme Vibration Resistance (iTHERM StrongSens): For applications near high-vibration equipment like turbines or compressors, the StrongSens insert offers resistance greater than 60g, ensuring long-term measurement stability and preventing mechanical failure.
-
Industry-Leading Response (iTHERM QuickSens): With a response time of just 1.5 seconds, the QuickSens technology ensures that even the smallest temperature fluctuations are detected almost instantly, providing superior control in sensitive thermal processes.
-
Global Digital Connectivity: The integrated iTEMP transmitter supports HART, PROFIBUS PA, and FOUNDATION Fieldbus. Optional Bluetooth connectivity enables wireless commissioning and diagnostics via mobile devices, improving safety in hazardous or hard-to-reach locations.
