Critical Technical Advantages
-
Precision and Stability: With a measuring range of -200 to +600 °C, the TR65 excels in both cryogenic applications and mid-range industrial heating processes. The RTD technology ensures a linear signal with minimal drift over time compared to thermocouples.
-
Hazardous Area Versatility: The TR65 carries comprehensive global certifications for hazardous locations, including Intrinsic Safety (Ex ia), Flameproof (Ex d), and Non-sparking (Ex nA). This allows for a single instrument standard across an entire refinery or chemical plant.
-
Modular DIN Standard Design: Built to comply with DIN 43772 and DIN EN 50446, the TR65 offers a high degree of insert compatibility. This means the measurement insert can be easily replaced or upgraded without changing the entire assembly, reducing spare part inventory and maintenance costs.
-
Advanced Signal Integration: When equipped with an optional iTEMP head transmitter, the TR65 supports all common communication protocols (4-20mA, HART, PROFIBUS PA, or FOUNDATION Fieldbus). This enhances measurement reliability by digitizing the signal at the source, eliminating errors from lead wire resistance.
-
Robust Environmental Protection: With an IP68 protection rating, the device is completely dust-tight and protected against prolonged immersion in water. It can handle static pressures up to 75 bar, making it suitable for high-pressure process lines and vessels.
-
Customizable Immersion: The modular concept allows for customer-specific immersion lengths and various process connections, ensuring the sensor is positioned exactly where the most accurate temperature profile exists.
