Q&A

Q1: What type of sensor technology does the PMC11-AA1U1HBWBJA use, and why is it beneficial?

A: The PMC11-AA1U1HBWBJA features a capacitive ceramic sensor with a non-oil-filled (dry) measuring cell . The sensor element is made of 99.9% Al₂O₃ ceramic with high abrasion resistance. This oil-free design eliminates the risk of oil leakage, a common failure mode in traditional pressure sensors, and provides excellent long-term stability (0.2% of URL/year) . The ceramic sensor is also highly resistant to wear and corrosion, making it ideal for demanding industrial applications .

Q2: What is the pressure range and overload protection for this model?

A: The PMC11-AA1U1HBWBJA has a gauge pressure measuring range of 0 to 1 bar (100 kPa / 15 psi) . It features robust overload protection rated at 10 bar (1 MPa / 150 psi) , ensuring reliable operation even during pressure spikes . The "1H" in the order code indicates the 1 bar range, while the overload protection is an integral safety feature .

Q3: What are the electrical and process connections for installation?

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 . The process connection is a G1/2" male thread (ISO228) with 316L stainless steel construction, and the seal material is FKM (Viton®), suitable for a wide range of media including gases, vapors, and liquids . The compact design with standard G1/2" thread simplifies integration into existing piping systems .
