Ключевые технические преимущества
-
Vacuum-Resistant Ceramic Sensor: The PTC31B uses a dry capacitance ceramic sensor that is high-vacuum resistant up to 0 bar absolute. Unlike metallic diaphragms, the Ceraphire ceramic cell does not suffer from permanent deformation under vacuum, ensuring long-term measurement stability
-
IO-Link Connectivity: The device is IO-Link capable, which significantly simplifies integration into all standard fieldbus systems. This allows for remote parameterization, easy device replacement, and reduced wiring complexity.
-
Onsite Visibility: The switch includes a bright digital display and status LEDs, allowing for immediate function checks and process information directly at the measurement point.
-
Decentralized Control: With its integrated switching electronics, the PTC31B can manage control tasks locally, reducing the load on the central PLC and providing an economic solution for process monitoring.
-
High Sensitivity: The device can handle minimum spans as low as 0 to 20 mbar, providing highly reliable insights even in low-pressure applications.
-
Abrasion and Chemical Resistance: The ceramic membrane is naturally resistant to abrasive particles and aggressive media, leading to higher process availability and reduced maintenance compared to traditional sensors.
