SAMSON(萨姆森)定位器:气动控制阀的自动化
定位器确保阀门位置(受控变量)与输入信号(参考变量)的预定分配。它们将气动或电气自动化设备(控制器、控制站、过程控制系统)发出的控制信号与控制阀的位置或开启角度进行比较,并提供相应的输出信号压力。定位器通常用作伺服增压器,因为它们将低能量信号转换为强比例信号压力,最高供应压力 (6 bar/90 psi)。它们可用于标准和分程操作。
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拥有 100 多年的控制阀工程经验和专业知识。1957 年,SAMSON向德国市场推出了第一台气动定位器。从那时起,SAMSON增强和完善了自己的定位器、它们的附件以及它们与各种阀门型号和阀门附件的相互作用。
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专注于用户:所有数字定位器的自动启动和经过验证的操作结构包含众多细节,例如按下按钮进行初始化,使用一个旋转按钮方便操作,易于阅读的显示屏,其阅读方向可旋转 180°,有助于使用户更容易启动和操作。
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的定位器很容易适应手头的控制任务——无论是现场使用,还是在带有诊断功能的 3730、3731 和 3793 系列定位器中,使用TROVIS-VIEW 软件在计算机上操作。
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.
• Available for all versions
SAMSON数字定位器有单作用或双作用定位器,用于连接气动线性或旋转执行器。由于采用数字信号处理技术,这些定位器与传统定位器相比具有以下优势:
- 操作简单
- 具有可旋转读取方向的 LCD
- 初始化期间的自动零位和跨度校准
- 自动检测执行器中的故障
- 作用方向与安装位置无关
- 零点持续监控
- 耗气量低
- 将所有参数永久存储在 EEPROM 中(防止断电)
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)
具有单作用或双作用功能的TROVIS SAFE 数字定位器是经过 SIL 认证的设备,用于连接到安全仪表系统中的气动控制阀。除了集成阀门诊断之外,它们还执行全行程测试 (FST) 和部分行程测试 (PST),并包含用于开/关阀门和 HART® 通信的现成配置参数。
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.
