重要な技術的利点
-
Vacuum-Proof Ceramic Sensor: The capacitive ceramic cell is designed to be fully vacuum-proof. Unlike metallic diaphragms that can be permanently deformed by vacuum, the ultra-hard Ceraphire membrane remains stable, ensuring reliability in distillation columns or vacuum extraction processes.
-
Integrated Breakage Detection: For enhanced process safety, the PMC51 features active membrane breakage detection. If the ceramic sensor is physically damaged, the device immediately signals an error, preventing undetected measurement failures in critical safety loops.
-
High Purity and Resistance: The 99.9% Al2O3 ceramic sensor is virtually inert to corrosive chemicals and highly resistant to abrasive particles. It is also condensation-resistant, which is vital for cold-water applications in warm, humid hygienic environments.
-
Safety by Design: The device is certified to SIL2 according to IEC 61508 and IEC 61511, making it suitable for use in safety instrumented systems. また、高精度が求められる用途向けに、±0.075%の「プラチナ」精度等級も提供しています。.
-
Flexible Installation: Available with a wide range of process connections—including threads, flanges, and various hygienic fittings—and the option for factory-mounted, leak-tested manifolds to simplify onsite installation.
-
User-Friendly Operation: Menu-guided commissioning via the local display or digital protocols (HART, PROFIBUS PA, FOUNDATION Fieldbus) allows for a quick setup and reduced maintenance time.
