1、萨姆森定位器 http:/www.samson- 电话:021-31121070Samson positioner combined with control valve use characteristics文章来源：http:/www.samson- Samson positioner ensures that the valve position (controlled variable) is pre-assigned to the input signal (reference variable), the control signal from the pneumatic or e
2、lectric automation device (controller, process control system) and the position or opening angle of the control valve Compare and provide the corresponding output signal pressure. The Samson positioner is typically used as a servo booster to convert low energy signals to a strong proportional signal
3、 pressure up to the maximum supply pressure (6 bar / 90 psi) for standard and split operation.1, diagnosisDue to the increased automation of the factory, the Samson positioner is used not only for the valve of the throttle valve but also for the valve for the on/off application. All SAMSON Samson po
4、sitioners can handle the classic analog control circuit. The TROVIS SAFE positioner also allows for discrete analysis of set points as well as partial stroke testing, making it ideal for installation on on/off valves.The special positioner version also allows discrete analysis of the setpoints of th
5、e installed on/off valves and partial stroke testing. The EXPERTplus valve diagnostics function is integrated into all positioner versions to record, save and analyze valve status data.2, communicationFull integration of control valves into process control and asset management systems allows for 萨姆森
6、定位器 http:/www.samson- 电话:021-31121070full use of Samson locator functions such as status logging and diagnostics. In addition, this manufacturer-independent integration allows the control valve to be configured and activated from a central location.The 3730 and 3731 Series positioners support standa
7、rd digital interfaces and protocols such as HART, PROFIBUS PA and FOUNDATIONTM fieldbus, and many device integration files for engineering tools and systems can be downloaded.3, securityA new TROVIS SAFE series has been added to the Samson positioner series for use in safety instrumented systems. In
8、 safety instrumented systems, control valves act as safety valves by opening or closing pipes in emergency situations, as described in the IEC 61508 and IEC 61511 (SIL) standards, which place high demands on functional safety.A smart positioner with diagnostics can be used to enhance or even replace
9、 the function of a solenoid valve mounted on a shut-off valve assembly, improving reliability, for example by performing a conventional partial stroke test. TROVIS SAFE positioners can be used when observing the requirements of IEC 61511 and the hardware fault tolerance required in safety instrument
10、ed systems up to SIL 2 (single device / HFT = 0) and SIL 3 (redundant configuration / HFT = 1) .The Samson positioner is easy to operate, with all digital positioners automatic activation and proven operating structure and numerous details, such as push button initialization, easy operation with a rotary button, easy to read display, and read direction can be rotated 180, user It can be easily started and operated.点击图标下载 App
