Cole-Parmer 912027 压力/真空系统

创建您自己的高精度系统来监视或控制您的应用

组装一个完整的系统，以满足您的监控需求。首先选择适合您应用范围的传感器。然后订购指示器或控制器-指示器和控制器均为七个范围。完整系统带有校准器微调您的仪表或控制器。传感器提供了改进的跟踪能力，长期维护校准。更换传感器时，不需要重新校准。这些传感器适合与汞泵和油泵共用。电阻式传感器提供增强的稳定性和自动温度补偿网络。传感器在半温度标准热电堆下操作。用于高真空的应用。

膜片式传感器全面快速响应-不到一秒钟。选择一个由316不锈钢或硅膜片式传感器或根据您的应用选择。

指示器提供精确的压力/真空数字读数。单孔安装可让您安装到面板开孔仪表，测量2-3/4''方形或2-3/4“直径3-3/8''（Hastings, Varian, TeleVac，以及其他仪表）。包括安装硬件 指示器包括10英尺的电缆连接传感器和5-1/2-ft电源线115 VAC操作。订购可选的20英尺延长线-扩展不会影响校准。型号可供220 VAC操作-详细信息请致电我们的应用专家。

控制器有指示器的所有功能，加上两个独立设置的SPDT继电器控制高和低控制。通过前面板按钮轻松调整设定点到任何值，在机器背面的螺丝终端连接继电器输出。

校准器调整您的仪表或控制器快速轻松地显示出厂规格（±0.2％）。校准器提供了精确的零点和量程输入值。校准测量3'' 宽×2英寸（高）×5-3/4'' 深. 型号 68801-40，-41，-42，-43有NW16连接器。

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.
