描述
FOXBORO 130M-N4是一款气动控制器，具体来说，是Foxboro 130系列仪表的一部分。Foxboro（现隶属于施耐德电气，旗下拥有EcoStruxure Foxboro DCS品牌）是一家领先的过程控制仪表制造商，尤其专注于工业自动化领域的气动设备。
概述
该控制器专为工业过程中的精确气动控制而设计。与现代电子或数字控制器不同，它使用气压信号进行操作，因此适用于电信号可能存在危险或不太理想的环境。它常用于需要可靠、持续控制以实现高效过程管理的场合。
主要参数和规格
制造商：Foxboro（原名Invensys Foxboro，现隶属于施耐德电气）
零件编号：130M-N4
产品类型：气动控制器/气动指示控制器
系列：Foxboro 130系列
工作原理：
气源：通常需要约20-22 PSI（140-150 kPa）的气源压力。
输入/输出：输入（测量值）和输出（阀门或执行器的控制信号）均采用3-15 PSI（20-100 kPa）的标准气动控制信号。
显示屏：通常采用清晰醒目的显示屏，并配有醒目的大型彩色指针，可连续显示变量的全量程并有效指示控制器偏差。
控制单元：设计有独立的自动和手动控制单元，可轻松拆卸或维护任一部件，而不会干扰工艺流程，从而避免代价高昂的停机。
切换：采用“积分平衡”技术，可在自动和手动模式之间实现无扰动切换，确保平稳过渡，不会对工艺流程造成干扰。
环境限制：可在约-20至+65°C的环境温度范围内工作。
重量：约7.72磅（约3.5公斤）。

The FOXBORO 130M-N4 is a pneumatic controller,specifically part of the Foxboro 130 Series of instruments.Foxboro(now part of Schneider Electric,under the EcoStruxure Foxboro DCS brand)was a prominent manufacturer of process control instrumentation,especially pneumatic devices,for industrial automation.
Overview
This controller is designed for precise pneumatic control in industrial processes.Unlike modern electronic or digital controllers,it operates using air pressure signals,making it suitable for environments where electrical signals might be hazardous or less desirable.It’s often used where reliable,continuous control is required for efficient process management.
Key Details and Specifications
Manufacturer:Foxboro(historically Invensys Foxboro,now part of Schneider Electric)
Part Number:130M-N4
Product Type:Pneumatic Controller/Pneumatic Indicating Controller
Series:Foxboro 130 Series
Operation:
Pneumatic Supply:Requires an air supply pressure typically around 20-22 PSI(140-150 kPa).
Input/Output:Operates with standard pneumatic control signals of 3-15 PSI(20-100 kPa)for both input(measured value)and output(control signal to a valve or actuator).
Display:Often features a highly visible and bold display with large,brightly colored pointers for continuous full-scale display of variables and effective indication of controller deviation.
Control Units:Designed with independent automatic and manual control units,allowing for easy removal or servicing of either part without disturbing the process,thus avoiding costly shutdowns.
Transfer:Features”integral balancing”for bumpless transfer between automatic and manual modes,ensuring a smooth transition without process upsets.
Environmental Limits:Can operate in environmental temperatures ranging from approximately-20 to+65°C.
Weight:Around 7.72 lbs(approximately 3.5 kg).
Application
The FOXBORO 130M-N4 pneumatic controller is used in various industrial applications where pneumatic control loops are still in operation.These typically include:
Boiler and burner control systems
Chemical processing plants
Oil and gas facilities
Power generation plants
Any process requiring precise and reliable control using pneumatic signals.
