重要な技術的利点
-
Robust Rope Construction: The sensors are fitted to a primary metal rope that can reach lengths of up to 60 meters (approximately 200 feet). This flexibility allows the assembly to adapt to the dynamic conditions of a silo, such as the shifting lateral forces caused by moving bulk solids or the changing levels in oil storage tanks.
-
High Sensor Density: With the ability to integrate up to 20 RTD or Thermocouple points along a single cable, the TMS31 provides a high-resolution vertical temperature profile. This is essential for early hotspot detection in grain silos to prevent spoilage or spontaneous combustion.
-
Specialized Coatings: For demanding food or chemical storage, the probe can be equipped with silicone or PTFE coatings. These materials prevent dust and particles from adhering to the probe, ensuring accurate readings and preventing “bridging” of bulk materials.
-
Optimized for Hazardous Areas: The TMS31 is intrinsically safe and certified for use in explosive dust (Ex t) and gas (Ex ia) atmospheres. This is a vital safety feature for grain storage, where high concentrations of organic dust pose a constant explosion risk.
-
High Process Pressure Support: Despite its flexible design, the TMS31 can handle static process pressures up to 40 bar (580 psi), making it suitable for pressurized storage vessels.
-
Advanced Digital Integration: The device supports the full range of iTEMP transmitters, enabling digital communication via HART, PROFIBUS PA, or FOUNDATION Fieldbus. This reduces wiring complexity by multiplexing several temperature points into a single digital signal.
