  FAQs

  Q1: What is the pressure measurement range of the PMC11-AA1L1FBWBJA?

  A: This transmitter measures gauge pressure from 0 to 400 mbar (0 to 6 psi) . The "1F" in the order code specifies the 400 mbar range, making it ideal for low-pressure applications such as level measurement in open tanks. It can withstand an overload limit of 6 bar (87 psi) without damage .

  Q2: What type of sensor technology does this pressure transmitter use, and what are its advantages?

  A: The PMC11-AA1L1FBWBJA features a capacitive ceramic sensor with a non-oil-filled (dry) measuring cell . The sensing element is made of 99.9% Al₂O₃ ceramic, which provides excellent wear resistance and chemical compatibility. The oil-free design eliminates the risk of oil leakage, a common failure mode in traditional pressure sensors, and ensures high long-term stability (0.2% of URL/year).

  Q3: What are the electrical and process connections for the PMC11-AA1L1FBWBJA?

  A: The transmitter uses an M12 plug (4-pin) electrical connection with IP65/IP67 protection, providing dust-tight and water-resistant operation suitable for harsh industrial environments . The process connection is a G1/2" male thread (ISO228) with 316L stainless steel construction and an FKM (Viton®) seal. The M12 connector enables quick, tool-free installation and easy sensor replacement.
