詳細(xì)介紹

Overview
斯坦福Stanford Research Systems發(fā)布CTC100 低溫溫度控制器可以以毫開爾文分辨率(mk)監(jiān)測和控制溫度。
Introducing the new CTC100 Cryogenic Temperature Controller—a high performance instrument that can monitor and control temperatures with millikelvin resolution.

CTC100低溫溫度控制器的配置適合廣泛的研究和工業(yè)應(yīng)用。

設(shè)備由四個(gè)傳感器輸入、兩個(gè)供電和四個(gè)模擬電壓輸出以及多達(dá)六個(gè)反饋控制回路組成。提供四個(gè)通用模擬和八個(gè)數(shù)字I/O,以及自動(dòng)設(shè)置PID參數(shù)的自動(dòng)調(diào)諧功能。










Sensor Inputs

CTC100提供四個(gè)溫度輸入,可以支持RTD、熱敏電阻和二極管。每個(gè)溫度輸入通道都有自己的24位ADC,具有11個(gè)輸入范圍,并配有自己獨(dú)立的激勵(lì)電流源。

通道設(shè)置菜單

內(nèi)置各種傳感器的標(biāo)準(zhǔn)校準(zhǔn)曲線,每個(gè)傳感器最多可輸入400點(diǎn)的自定義校準(zhǔn)曲線。每個(gè)傳感器輸入都有高電平和低電平或變化率警報(bào)。傳感器輸入可以進(jìn)行低通濾波以減少噪聲,和/或與另一個(gè)通道進(jìn)行差分。


Powered and Analog Voltage Outputs

CTC100有兩個(gè)加熱器輸出,每個(gè)輸出可向25? 加熱。此外,在外部放大器的幫助下,可以使用四個(gè)模擬電壓I/O通道來驅(qū)動(dòng)加熱器。


PID Feedback Control

選擇菜單

CTC100最多可提供六個(gè)反饋控制回路,通過不斷調(diào)整加熱器功率,可以對每個(gè)加熱器輸出進(jìn)行精確的溫度控制。CTC100的任何通道都可以被選擇作為每個(gè)反饋回路的輸入。反饋時(shí)間常數(shù)可以在200毫秒和10小時(shí)之間調(diào)整。

每個(gè)通道最多可以存儲十組PID參數(shù)。設(shè)定點(diǎn)可以以固定的速率傾斜。


Analog and Digital I/Os

CTC100配有四個(gè)通用±10 V電壓I/O通道,由24位ADC讀取。它還有八個(gè)數(shù)字I/O通道,可以與用戶程序進(jìn)行交互。

四個(gè)5A繼電器可用于過程控制。三個(gè)虛擬通道不連接到任何物理輸入,允許顯示、繪制和記錄計(jì)算值(如兩個(gè)通道之間的差,或用戶程序計(jì)算的值)。


Numeric and Graphical Display

Numeric Display

The CTC100's color LCD display can show any combination of temperature measurements and heater outputs on graphs or numeric displays. Up to eight channels can be plotted either on a single graph with a common Y axis, or on separate graphs with independent Y axis. Touchscreen operation makes the instrument versatile and easy to use.

CTC100的彩色液晶顯示器可以在圖形或數(shù)字顯示器上顯示溫度測量值和加熱器輸出的任何組合。最多可以在具有公共Y軸的單個(gè)圖形上繪制八個(gè)通道,也可以在具有獨(dú)立Y軸的單獨(dú)圖形上繪制。觸摸屏操作使儀器用途廣泛且易于使用。


Data Logging

Up to 1 million readings per channel can be logged to the CTC100's internal memory. For longer-term storage, data can be logged to standard USB memory sticks or hard drives. CTC100的內(nèi)部存儲器可以記錄每個(gè)通道多達(dá)100萬個(gè)讀數(shù)。對于長期存儲,數(shù)據(jù)可以記錄到標(biāo)準(zhǔn)的USB記憶棒或硬盤驅(qū)動(dòng)器中。

Data logged to USB devices can be transferred to a computer by plugging the USB device into a PC. A Windows applications can be downloaded from SRS website to graph CTC100 log files.通過將USB設(shè)備插入PC,可以將記錄到USB設(shè)備的數(shù)據(jù)傳輸?shù)接?jì)算機(jī)??梢詮腟RS網(wǎng)站下載Windows應(yīng)用程序來繪制CTC100日志文件。


Computer Communications

Each of the CTC100's front-panel controls has a corresponding text command that can be sent over USB, Ethernet, and either RS-232 or an optional GPIB interface.

CTC100的每個(gè)前面板控件都有一個(gè)相應(yīng)的文本命令,可以通過USB、以太網(wǎng)和RS-232或可選的GPIB(另行選購)接口發(fā)送。

Graphical Display

When the USB interface is used, the CTC100 appears on the computer as a standard COM port and can be controlled by any software that is compatible with an RS-232 port.

當(dāng)使用USB接口時(shí),CTC100作為標(biāo)準(zhǔn)COM端口出現(xiàn)在計(jì)算機(jī)上,并且可以由任何與RS-232端口兼容的軟件控制。


User Programs

User programs (macros), consisting of one or more remote commands, can be uploaded to the CTC100. This is done by either sending them through one of the communications ports or by saving them as text files on a USB memory device and then plugging the device into the CTC100. Program macros can also be entered and edited from the front panel.

由一個(gè)或多個(gè)遠(yuǎn)程命令組成的用戶程序(宏)可以上傳到CTC100。這可以通過其中一個(gè)通信端口發(fā)送,或者將它們保存為USB存儲設(shè)備上的文本文件,然后將設(shè)備插入CTC100來完成。程序宏也可以從前面板輸入和編輯。
