Cole-Parmer 912027 壓力/真空系統(tǒng)

創(chuàng)建您自己的高精度系統(tǒng)來(lái)監(jiān)視或控制您的應(yīng)用

組裝一個(gè)完整的系統(tǒng)，以滿(mǎn)足您的監(jiān)控需求。首先選擇適合您應(yīng)用范圍的傳感器。然后訂購(gòu)指示器或控制器-指示器和控制器均為七個(gè)范圍。完整系統(tǒng)帶有校準(zhǔn)器微調(diào)您的儀表或控制器。傳感器提供了改進(jìn)的跟蹤能力，長(zhǎng)期維護(hù)校準(zhǔn)。更換傳感器時(shí)，不需要重新校準(zhǔn)。這些傳感器適合與汞泵和油泵共用。電阻式傳感器提供增強(qiáng)的穩(wěn)定性和自動(dòng)溫度補(bǔ)償網(wǎng)絡(luò)。傳感器在半溫度標(biāo)準(zhǔn)熱電堆下操作。用于高真空的應(yīng)用。

膜片式傳感器全面快速響應(yīng)-不到一秒鐘。選擇一個(gè)由316不銹鋼或硅膜片式傳感器或根據(jù)您的應(yīng)用選擇。

指示器提供精確的壓力/真空數(shù)字讀數(shù)。單孔安裝可讓您安裝到面板開(kāi)孔儀表，測(cè)量2-3/4''方形或2-3/4“直徑3-3/8''（Hastings, Varian, TeleVac，以及其他儀表）。包括安裝硬件 指示器包括10英尺的電纜連接傳感器和5-1/2-ft電源線115 VAC操作。訂購(gòu)可選的20英尺延長(zhǎng)線-擴(kuò)展不會(huì)影響校準(zhǔn)。型號(hào)可供220 VAC操作-詳細(xì)信息請(qǐng)致電我們的應(yīng)用專(zhuān)家。

控制器有指示器的所有功能，加上兩個(gè)獨(dú)立設(shè)置的SPDT繼電器控制高和低控制。通過(guò)前面板按鈕輕松調(diào)整設(shè)定點(diǎn)到任何值，在機(jī)器背面的螺絲終端連接繼電器輸出。

校準(zhǔn)器調(diào)整您的儀表或控制器快速輕松地顯示出廠規(guī)格（±0.2％）。校準(zhǔn)器提供了精確的零點(diǎn)和量程輸入值。校準(zhǔn)測(cè)量3'' 寬×2英寸（高）×5-3/4'' 深. 型號(hào) 68801-40，-41，-42，-43有NW16連接器。

Create your own high-accuracy system to monitor or control your application

Assemble a complete system that meets your monitoring needs. First choose a sensor with the range appropriate for your application. Then order a indicator or controller--both are available in seven ranges. Complete your system with a compatible calibrator to fine tune your meter or controller.

Sensors provide improved tracking ability and maintain calibration over long periods of time. When replacing a sensor, there's no need for recalibration. These sensors are suited for use with mercury and oil pumps.

Pirani type sensors offer enhanced stability and an automatic temperature compensation network. Sensors operate at half the temperature of standard thermopile sensors. Use for high-vacuum applications.

Diaphragm type sensor offers quick response--less than one second full-scale. Select a diaphragm type sensor made from 316 stainless steel or silicon based on your application.

Indicators provide precise digital readout of pressure/vacuum. Single-hole installation lets you mount meters into panel cutouts that measure 2-3/4'' square or 2-3/4'' up to 3-3/8'' in diameter (such as those for Hastings, Varian, TeleVac, and other meters). Mounting hardware is included. Indicators include 10-ft cable to connect sensor and 5-1/2-ft power cord for 115 VAC operation. Order optional 20-ft extension cable--extension won't affect calibration. Models are available for 220 VAC operation--call our Application Specialists for details.

Controllers have all the features of the indicators plus two independently set SPDT relays for control of high and low limits. Easily adjust set points to any value with front-panel push buttons; connect relay outputs at screw terminals at back of unit.

Calibrators let you readjust your meter or controller display quickly and easily to factory specifications (±0.2%). Calibrators provide precise zero and span input values. Calibrators measure 3''W x 2''H x 5-3/4''D.

Models 68801-40, -41, -42, and -43 have NW 16 connections.
