TESCOM執(zhí)行器ER3000系列產品介紹機選型
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(電子調節(jié)器)是一種通用的0至100 psi壓力控制器。它可以與任何氣動調節(jié)器或閥門配合使用,以將Cv高達45的壓力從低于大氣壓控制到20,000 psi。可以通過模擬輸入(4-20mA,1-5V或0- 10V),數(shù)字RS485接口或下載的配置文件。
RS485接口使計算機壓力控制比以往任何時候都容易。使用低成本的RS232到RS485適配器,可以將控制器快速連接到任何PC上的標準串行通信端口中。
該通信通道還提供了許多內部參數(shù)的編程,包括PID調整變量,零和跨度,操作模式,限制等。
反饋可以從ER3000的內部溫度補償傳感器或外部傳感器(4-20mA,1-5V或0-10V)獲得。第二個選項允許將傳感器定位在實際生產線的下游。
有四種操作模式。內部反饋模式(使用模擬設定值時,使控制器成為I / P),并使用內部傳感器作為反饋源。外部反饋模式使用外部傳感器作為反饋。級聯(lián)模式在一個循環(huán)內創(chuàng)建一個循環(huán)。內部回路使用內部傳感器進行反饋,而外部回路使用外部傳感器進行反饋。手動模式允許直接控制電磁閥(用于排除系統(tǒng)故障)。
總而言之,ER3000電子壓力調節(jié)器易于安裝和運行,但仍可提供最苛刻的用戶所需的靈活性。
標準功能:
包括RS485通信。
1/8英寸的進氣口和排氣口,1/4英寸的受控輸出口。
最大入口壓力= 120 psig。
0至100 psig內部傳感器。
包括Windows / DOS軟件包。
需要24 VDC電源。
