重要な技術的利点
-
High-Pressure Resistance: Engineered to withstand process pressures up to 500 bar (7,252 psi). The use of barstock thermowells ensures the integrity of the process boundary even under extreme mechanical loads.
-
Second Process Seal with Failure Indication: For critical safety applications, the TM151 offers a secondary seal. If the primary thermowell fails, this seal prevents process media escape and provides a specific failure indication, allowing operators to address device health before a containment breach occurs.
-
Tool-Free Maintenance (iTHERM QuickNeck): Featuring a divisible extension neck, the TM151 allows the transmitter and insert to be removed for recalibration without tools and without opening the terminal head. This drastically reduces maintenance time and prevents wiring errors.
-
Vibration-Resistant Technology (iTHERM StrongSens): The StrongSens insert provides vibration resistance exceeding 60g. This ensures a long service life and prevents measurement drift in high-vibration areas such as compressor discharges or high-velocity steam lines.
-
Rapid Process Control (iTHERM QuickSens): With a response time of just 1.5 seconds, the QuickSens technology allows the control system to react almost instantly to temperature changes, leading to better product quality and energy savings.
-
Wireless Accessibility: Integrated iTEMP transmitters with optional Bluetooth connectivity allow for safe, wireless configuration and diagnostics via the SmartBlue app, which is especially useful for sensors located in hard-to-reach or hazardous areas.
