SAMSON（薩姆森）定位器：氣動(dòng)控制閥的自動(dòng)化
定位器確保閥門(mén)位置（受控變量）與輸入信號(hào)（參考變量）的預(yù)定分配。它們將氣動(dòng)或電氣自動(dòng)化設(shè)備（控制器、控制站、過(guò)程控制系統(tǒng)）發(fā)出的控制信號(hào)與控制閥的位置或開(kāi)啟角度進(jìn)行比較，并提供相應(yīng)的輸出信號(hào)壓力。定位器通常用作伺服增壓器，因?yàn)樗鼈儗⒌湍芰啃盘?hào)轉(zhuǎn)換為強(qiáng)比例信號(hào)壓力，最高供應(yīng)壓力 (6 bar/90 psi)。它們可用于標(biāo)準(zhǔn)和分程操作。
Positioners ensure a predetermined assignment of the valve position (controlled variable) to the input signal (reference variable). They compare the control signal issued by pneumatic or electric automation equipment (controller, control station, process control system) to the position or opening angle of the control valve and supply a corresponding output signal pressure. Positioners are often used as servo-booster as they convert low-energy signals into strong proportional signal pressures up to the maximum supply pressure (6 bar/90 psi). They can be used in standard and splitrange operation.
SAMSON擁有 100 多年的控制閥工程經(jīng)驗(yàn)和專(zhuān)業(yè)知識(shí)。1957 年，SAMSON向德國(guó)市場(chǎng)推出了第一臺(tái)氣動(dòng)定位器。從那時(shí)起，SAMSON增強(qiáng)和完善了自己的定位器、它們的附件以及它們與各種閥門(mén)型號(hào)和閥門(mén)附件的相互作用。
SAMSON can draw on more than 100 years of experience and expertise in control valve engineering. In 1957, SAMSON launched the first pneumatic positioner onto the German market. Since then, SAMSON have enhanced and perfected our positioners, their attachment and their interaction with a wide variety of valve models and valve accessories.

OPERATION
SAMSON專(zhuān)注于用戶(hù)：所有數(shù)字定位器的自動(dòng)啟動(dòng)和經(jīng)過(guò)驗(yàn)證的操作結(jié)構(gòu)包含眾多細(xì)節(jié)，例如按下按鈕進(jìn)行初始化，使用一個(gè)旋轉(zhuǎn)按鈕方便操作，易于閱讀的顯示屏，其閱讀方向可旋轉(zhuǎn) 180°，有助于使用戶(hù)更容易啟動(dòng)和操作。
SAMSON focus on the user: automatic start-up and a proven operating structure in all our digital positioners as well as numerous details, such as initialization at the push of a button, convenient operation using one rotary pushbutton, a display that is easy to read and whose reading direction can be turned by 180°, contribute to making start-up and operation easier for the user.
SAMSON的定位器很容易適應(yīng)手頭的控制任務(wù)——無(wú)論是現(xiàn)場(chǎng)使用，還是在帶有診斷功能的 3730、3731 和 3793 系列定位器中，使用TROVIS-VIEW 軟件在計(jì)算機(jī)上操作。
SAMSON positioners are easily adapted to the control task at hand – either on site or, in Series 3730, 3731, and 3793 Positioners with diagnostics, on a computer using TROVIS-VIEW software.

SAMSON數(shù)字定位器有單作用或雙作用定位器，用于連接氣動(dòng)線(xiàn)性或旋轉(zhuǎn)執(zhí)行器。由于采用數(shù)字信號(hào)處理技術(shù)，這些定位器與傳統(tǒng)定位器相比具有以下優(yōu)勢(shì)：
- 操作簡(jiǎn)單
- 具有可旋轉(zhuǎn)讀取方向的 LCD
- 初始化期間的自動(dòng)零位和跨度校準(zhǔn)
- 自動(dòng)檢測(cè)執(zhí)行器中的故障
- 作用方向與安裝位置無(wú)關(guān)
- 零點(diǎn)持續(xù)監(jiān)控
- 耗氣量低
- 將所有參數(shù)永久存儲(chǔ)在 EEPROM 中（防止斷電）
SAMSON digital positioners are single-acting or double-acting positioners for attachment to pneumatic linear or rotary actuators. Due to their digital signal processing technology, these positioners have the following advantages over conventional positioners:
- Simple operation
- LCD with rotatable reading direction
- Automatic zero and span calibration during initialization
- Automatic detection of faults in the actuator
- Direction of action independent of mounting position
- Continuous monitoring of zero point
- Low air consumption
- Permanent storage of all parameters in EEPROM (protected against power failure)
具有單作用或雙作用功能的TROVIS SAFE 數(shù)字定位器是經(jīng)過(guò) SIL 認(rèn)證的設(shè)備，用于連接到安全儀表系統(tǒng)中的氣動(dòng)控制閥。除了集成閥門(mén)診斷之外，它們還執(zhí)行全行程測(cè)試 (FST) 和部分行程測(cè)試 (PST)，并包含用于開(kāi)/關(guān)閥門(mén)和 HART? 通信的現(xiàn)成配置參數(shù)。
TROVIS SAFE digital positioners with single-acting or double-acting function are SIL-certified devices for attachment to pneumatic control valves in safety-instrumented systems. In addition to the integrated valve diagnostics, they perform full stroke tests (FST) and partial stroke tests (PST) and contain ready-configured parameters for on/off valves and HART? communication.
