今天，Emersonintroduced the TopWorxTM DX PST with HART® 7. Units provide valuable valve data and diagnostic information, enabling the digital transformation of process applications. The new DX PST integrates seamlessly with existing valves and control systems, giving operators access to critical valve data, trends, and diagnostics that can be used to predict and schedule maintenance.
The DX PST’s partial stroke test ensures the system’s reliable function without shutting down the process. A safety feature that confirms the valve will fully close and stop the process if an emergency is detected, and the test is activated by simply pressing the local PST button—no additional equipment is required. To prevent critical failure in upset conditions, the unit will override testing to perform an emergency shutdown (ESD).
自适应DX PST经过严格和危险应用的操作认证，旨在确保阀门的完整性，改善石油和天然气，炼油厂，化学，工业能源和采矿应用的整体安全和设施的正常运行时间。
艾默生Switchbox的全球产品经理Prayag Vatsraj说：“流程行业的数字化转型继续使运营更安全，更有生产力。”“带有Hart 7的DX PST通过提供可靠的数据来支持数字转换，这些数据可提供宝贵的洞察力，以了解阀门组件的状况，以确保系统的完整性而不会关闭该过程。”
HART®协议（其规格由FieldComm组拥有）构建了另一层信息，以确保对数据，趋势和诊断的监视并绑定到工业互联网上。该信息可用于有效预测和安排维护。
Capable of Safety Integrity Level 3 (SIL 3), the DX PST is available with an integrated 2oo2 or 2oo3 solenoid valve redundancy when paired with ASCO™ Series Advanced Redundant Control System (ARCS) to further enhance safety and open terminals that allow an additional pressure transmitter along with two pressure switches. The discrete valve controller offers simple local and remote calibration.
