Q&A

Q1: What is the pressure measurement range and overload protection of the PMC11-AA1U1PBWBJA?

A: The PMC11-AA1U1PBWBJA measures gauge pressure from 0 to 10 bar (0 to 150 psi) . It features robust overload protection rated at 40 bar (600 psi), which is four times the full-scale range, ensuring reliable operation even during unexpected pressure spikes . The "1P" in the order code specifies the 10 bar range, while the overload protection is an integral safety feature of the sensor design.

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

A: The PMC11-AA1U1PBWBJA 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) and repeatability . This technology is particularly beneficial for applications involving aggressive media or where environmental contamination from oil leaks is a concern.

Q3: What are the electrical and process connections for the PMC11-AA1U1PBWBJA?

A: The transmitter uses a valve plug ISO4400 M16 (DIN 43650-A) electrical connection with IP65 / NEMA Type 4X 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 . The seal material is FKM (Viton®), which is compatible with a wide range of media including gases, vapors, and liquids. The standard G1/2" thread simplifies integration into existing piping systems without requiring adapters
