QDW50A Flush Diaphragm Pressure Transmitter

Flush Diaphragm Reduces Residue and Blockage

QDW50A is a pressure transmitter designed around “Flush Diaphragm Reduces Residue and Blockage.” The dedicated mechanical and connector structure simplifies installation, replacement and field maintenance. The dedicated mechanical, connector or mounting structure helps the instrument fit the intended pipe, tank, cabinet or equipment interface. The feature is directly relevant to slurry pipeline, food process and industrial process projects. Shorten installation time and simplify later field maintenance, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

Pressure Measurement for Process Media

QDW50A is a pressure transmitter designed around “Pressure Measurement for Process Media.” Matches the measuring structure to the specified medium and operating conditions. The sensing principle and material arrangement are matched to the process medium and the applications stated in the source table. The feature is directly relevant to slurry pipeline, food process and industrial process projects. Match the medium and process conditions of slurry pipeline applications, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

Standard Pressure Output for Control Systems

QDW50A is a pressure transmitter designed around “Standard Pressure Output for Control Systems.” Supports 4–20mA, 0–10V, 0–5V, RS485 for stable pressure measurement and system integration. The standardized signal path routes the measured value to PLCs, DCS platforms, displays or remote monitoring equipment. The confirmed values highlighted here are 4–20mA, 0–10V, 0–5V, RS485. The feature is directly relevant to slurry pipeline, food process and industrial process projects. Connect field measurements directly to existing plc and monitoring systems, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.
