Superior Sensing with GO Switch Technology
The D-Series is powered by TopWorx GO Switch sensing technology, which sets the benchmark for reliability in extreme conditions. Unlike standard proximity sensors, GO Switches are hermetically sealed, allowing them to outperform competitors in environments that are hot, cold, wet, dirty, or corrosive.
-
Best-in-Class Durability: The switches are designed to survive abusive and explosive conditions without losing calibration.
-
Precision Cam Design: The unique cam system allows for quick and accurate setting of switch positions. This precision reduces deadband and hysteresis to a minimum, ensuring that the control system receives the most accurate data regarding valve position.
主要な技術的利点
-
Global Standardization: With IECEx, ATEX, and UL certifications combined in a single model, along with regional approvals like NEPSI, KOSHA, InMetro, and EAC, the DXP simplifies procurement and maintenance for global operations.
-
Variety of Networks and Sensors: The DXP supports a wide range of bus networks (such as Foundation Fieldbus, DeviceNet, AS-Interface, and Profibus) and multiple sensor options to fit any control architecture.
-
Ease of Adjustment: The controller features color-coded Twist-Set cams. These allow for the easiest and fastest limit switch adjustment in the industry, significantly reducing commissioning time.
-
High-Visibility Display: An impact-resistant, highly visible position indicator provides clear local status of the valve position, even from a distance or in low-light plant conditions.
