QDW90A-G High Temperature Pressure Transmitter
High-temperature Structure for Hot Process MediaQDW90A-G is a pressure transmitter designed around “High-temperature Structure for Hot Process Media.” Separates sensitive electronics from hot process media for more reliable long-term measurement. The high-temperature arrangement protects sensitive electronics from continuous heat while maintaining a direct measurement path to the process. The feature is directly relevant to steam pipeline, process pipeline and industrial process projects. Keep measurement electronics away from continuous high-temperature stress, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation. | |
Hirschmann Connector for Reliable Field WiringQDW90A-G is a pressure transmitter designed around “Hirschmann Connector for Reliable Field Wiring.” Provides dependable pressure measurement for industrial automation systems. The product is organized around this specific field requirement without adding unrelated functions to the measuring point. The feature is directly relevant to steam pipeline, process pipeline and industrial process projects. Improve measurement clarity and maintenance efficiency in steam pipeline applications, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation. | |
Clear On-site Display for Faster InspectionQDW90A-G is a pressure transmitter designed around “Clear On-site Display for Faster Inspection.” Displays the measured value directly at the process point for easier inspection and commissioning. The local display makes the live value and operating state easier to verify during commissioning, inspection and routine maintenance. The feature is directly relevant to steam pipeline, process pipeline and industrial process projects. Check operating status directly without opening the control system, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation. | |
