TESCOM执行器ER3000系列产品介绍机选型
The ER3000 (Electronic Regulator) is a versatile 0 to 100 psi pressure controller. It can be used in conjunction with any pneumatically actuated regulator or valve to control pressure from subatmosphere to 20,000 psi with Cv‟s of up to 45. Setpoints can be provided via an analog input (4-20mA, 1-5V, or 0-10V), the digital RS485 interface, or a downloaded profile.
The RS485 interface makes pressure control by a computer easier than ever before. The controller can be wired quickly into the standard serial communication port found on any PC using a low-cost RS232 to RS485 adapter.
This communication channel also provides for the programming of a number of internal parameters, including PID tuning variables, zero and span, mode of operation, limits, etc.
Feedback can be derived either from the ER3000‟s internal temperature compensated sensor or an external transducer (4-20mA, 1-5V, or 0-10V). This second option allows for positioning the sensor downstream in the actual process line.
Four modes of operation are available. Internal feedback mode (which makes the controller an I/P when analog setpoints are used) and uses the internal sensor as the source of feedback. External feedback mode uses an external sensor as the feedback. Cascade mode creates a loop within a loop; the inner loop uses the internal sensor for feedback and the outer loop uses the external transducer for feedback. Manual mode allows for direct control of the solenoid valves (useful for troubleshooting the system).
In summary, the ER3000 electronic pressure regulator is easy to get up and running, yet offers the flexibility required by the most demanding user.
Standard features:
RS485 communications included.
1/8” inlet and exhaust ports, 1/4” controlled output port.
Maximum inlet pressure = 120 psig.
0 to 100 psig internal sensor.
Windows/DOS software package included.
24 VDC power required.
ER3000(电子调节器)是一种通用的0至100 psi压力控制器。它可以与任何气动调节器或阀门配合使用,以将Cv高达45的压力从低于大气压控制到20,000 psi。可以通过模拟输入(4-20mA,1-5V或0- 10V),数字RS485接口或下载的配置文件。
RS485接口使计算机压力控制比以往任何时候都容易。使用低成本的RS232到RS485适配器,可以将控制器快速连接到任何PC上的标准串行通信端口中。
该通信通道还提供了许多内部参数的编程,包括PID调整变量,零和跨度,操作模式,限制等。
反馈可以从ER3000的内部温度补偿传感器或外部传感器(4-20mA,1-5V或0-10V)获得。第二个选项允许将传感器定位在实际生产线的下游。
有四种操作模式。内部反馈模式(使用模拟设定值时,使控制器成为I / P),并使用内部传感器作为反馈源。外部反馈模式使用外部传感器作为反馈。级联模式在一个循环内创建一个循环。内部回路使用内部传感器进行反馈,而外部回路使用外部传感器进行反馈。手动模式允许直接控制电磁阀(用于排除系统故障)。
总而言之,ER3000电子压力调节器易于安装和运行,但仍可提供最苛刻的用户所需的灵活性。
标准功能:
包括RS485通信。
1/8英寸的进气口和排气口,1/4英寸的受控输出口。
最大入口压力= 120 psig。
0至100 psig内部传感器。
包括Windows / DOS软件包。
需要24 VDC电源。
