FAQs

Q1: What is the pressure measurement range of the PMC11-AA1U1QBWWJA?

A: This transmitter measures gauge pressure from 0 to 16 bar (0 to 240 psi). The "1Q" in the order code specifies the 16 bar range. It can withstand an overload limit of 60 bar (900 psi) without damage .

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

A: The PMC11-AA1U1QBWWJA 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-AA1U1QBWWJA?

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 and FKM (Viton®) seal . The standard G1/2" thread simplifies integration into existing piping systems.
