Muhim texnik afzalliklar
-
Superior Precision: The PMC71 offers a standard accuracy of ±0.05%, with a “Platinum” version reaching ±0.025%. This level of precision is essential for inventory control, custody transfer, and high-accuracy mass/volume calculations in tanks.
-
Maximum Safety (SIL 2/3): Certified for use in safety instrumented systems up to SIL 3 (in redundant configurations), the PMC71 features a gastight feedthrough. This secondary containment ensures that even if the process breaks through the primary seal, the electronics and the environment remain protected.
-
HistoROM Data Management: This innovative concept stores all device parameters and event logs on a removable memory module. It allows for effortless commissioning and maintenance; if a transmitter needs replacement, the configuration is simply swapped into the new unit without the need for re-parameterization.
-
Advanced Ceramic Durability: The capacitive Ceraphire membrane is virtually immune to the effects of vacuum, which typically causes “oil-oil” or metallic diaphragms to fail. It also features integrated breakage detection, providing an immediate alarm if the sensor integrity is compromised.
-
Dual-Chamber Housing: The two-chamber design separates the terminal compartment from the electronics compartment. This provides an additional layer of protection against moisture ingress and corrosive atmospheres during wiring or maintenance.
-
Overload Resistance: The high-purity ceramic sensor can handle significant overpressure (overload) events without shifting its zero point or damaging the sensor structure, ensuring long-term measurement stability.
