Thus, all the benefits exposed above are applicable to any of the three circuits composing the instrument : input,output and power.Recalibration of the instruments is realized in a fast and easy way. Opening the front cover grants access to the configuration jumpers. Additional Span and Offset potentiometers are directly accessible from the frontal part. These potentiometers are highly decoupled, minimizing the iterations needed to obtain a correct adjustment.In order to obtain a higher and quickest benefit of the DRF units, we recommend you to read carefully the information provided in this manual before proceeding to the installation of the instrument. In this manual you will find all technical data, both electrical and mechanical, needed for a correct instalation and utilization.Note : The DRF Isolated Signal Converter instruments have a characteristics label attached on the side of the instrument. Check that the information indicated on the label matches with your application requirements,and specially check that the value and type of the power supply needed matches the value and type of the power supply availble on your installation.The DRF series of Isolated Signal Converters,allow to convert process signals,temperatures, electrical signals, etc, to current loops or voltage signals for further retransmision, while introducing into the system galvanic isolation barriers between the input, the output and the power supply circuits.The DRF series of Isolated Signal Converters,offer an excellent relation between signal conversion speed and measurement accuracy. Offering a 0.2% accuracy and up to a 70ms response time depending on the model, these units can process information coming from probes or transducers, in such a way that can be quickly retransmitted in a fast and accurate form to remote data acquisition systems or PLC’s. The isolated signal converters of the ISC series are ideal to integrate into 12 bit data acquisition systems.Its powerful galvanic isolation of 3.500 V introduces high security to the measuring systems, preventing the propagation of those phenomenon which usually cause damage to the remote system, such as transient peaks or energy shocks in any of the circuits of the system. The galvanic isolation also acts as a strong CE barrier. The decoupling created between the input, output and power circuits avoids pernicious effects on the output, such as ground loops or signal leaks,which distort the acquired data and are extremely difficult to isolate once introduced into the signal.2-INSTALLATION____________________________________________O UTPUT J UMPERS P OT.

PCL431Current CalibratorOperator’s ManualM1889/0994GENERAL DESCRIPTIONThe OMEGA®PCL431 Hand-Held Current Calibrator is designed to be a complete 4-20mA loop calibrator delivering high accuracy in a small, easy to use package. Its microprocessor based circuitry gives the usera large number of input/output options and operating modes without unnecessary complexity.Current can be sourced into loads up to 1000 ohms or simulated with external power supplies of up to60VDC. When operated in the read mode the user can input a current from a signal source directly, or in the read/power mode the PCL431 will supply 24 volt loop power to a two wire device and simultaneously monitor the resultant loop current. Both read and source measurements can be displayed directly inmilliamps or as a percentage of a 4-20mA loop.Commonly used outputs (up to 3) can be stored in the PCL431’s non-volatile memory for quick recall. In addition, an auto-step mode allows the calibrator to step through the selected setpoints at a user defined dwell time of 5 to 60 seconds.INSTALLATIONUNPACKINGRemove the Packing List and verify that all equipment has been received. If you have any questions about the shipment, please call the OMEGA Customer Service Department at 1-800-622-2378 or (203) 359-1660.When you receive the shipment, inspect the container and equipment for any signs of damage.

Immediately report any damage to the shipping agent.NOTE:The carrier will not honor any claims unless all shipping material is saved for theirexamination. After examining and removing contents, save packing material and carton in theevent reshipment is necessary.Check to see if your calibrator kit is complete - it should include:1. Carrying case (Qty=1)2. T est leads (Qty=1 set)3. 9V battery (Installed)4. Operator’s Manual (Qty=1)SET-UPBefore beginning, become familiar with the keypad layout and the configuration of the input/output jacks.Remember, these jacks are used in multiple configurations so pay careful attention to how the test leads are connected for the specific application.CJS0994RAF2BAOPERATING PROCEDURE1. Turn on power and select the desired range by depressing the ”RANGE SELECT” key.NOTE: When operating in the “%” range, 4mA=0% and 20mA=100%.2. Connections are made as follows:Current Source - Use jacks 1 and 2 (1 is +).Current Simulate - Use jacks 2 and 3 (2 is +).Current Read - Use jacks 3 and 4 (4 is +).Current Read/Power - Use jacks 1 and 4 (1 is +).3. The and keys adjust the output value up or down. Holding the ramp keys continuously forseveral seconds will increase the scroll rate. Going beyond the endpoints (0 and 24mA) will cause theoutput to wrap around, thus allowing a quick return to either end of the scale.4. Three calibration points can be stored in non-volatile memory by scrolling to the desired output,depressing the Store key, and then the desired setpoint key.5. The auto step will automatically step through the stored setpoints at pre-defined intervals. When theauto-step key is first depressed, the display will indicate the dwell time (in seconds) between steps.The factory set value is 15 seconds but you can set this value, from 5 to 60 seconds, by usingthe and keys when the dwell time is being displayed. Once you have scrolled to the desireddwell time, release the or key and wait approximately 3 seconds until the calibrator begins toautomatically step through the 3 setpoints. The calibrator will continue the stepping process until anykey is pressed. Your chosen dwell time will remain in a non-volatile memory location until you chooseto change it.OPERATING CONSIDERATIONS AND PRECAUTIONS1. When operating in the current source mode, the PCL431 has the capability to drive loads up to 1000ohms as shown in Figure 1.Figure 1 - Current Source Mode2. When operating in the current simulate mode, the PCL431 acts like a two-wire transmitter controlling acurrent loop with an external voltage of up to 60 VDC as shown in Figure 2.Figure 2 - Current Simulate Mode3. When reading a current loop, the PCL431 can measure over a range of 0-24mA. Connections areshown in Figure 3.Figure 3 - Current Loop Readings4. The PCL431 can simultaneously power a device with 24 volts and display the current flowing throughthe loop. This is particularly useful when calibrating a two-wire transmitter. A typical application isshown in Figure 4.Figure 4 - PCL431 Simultaneous Power/DisplayACCURACYThe PCL431 is checked against an NIST traceable reference before shipment to verify that each range falls within the 0.05%, ±1 count, of full scale accuracy specification. Long term accuracy should remain within0.1%, ±1 count, of FSR. All of these ratings are based on a 25°C ambient temperature. A change of 10°Cwill cause approximately a 1000 ppm change (based on 100 ppm/C temp.) in the output or the equivalent of a 0.1% output change. Therefore, allowances must be made for error caused by wide temperaturevariations.。

如何通过互联网对所有过程实施远程监控简介基于以太网/互联网的数据监控产生了新的变革，我们可以以一种全新的方式对过程测量和控制进行访问。

使用标准的过程传感器例如热电偶或RTD（温度）、压力传感器、流量计或其它可以产生标准模拟或脉冲输出的传感器，您可以在绝大多数场所对数据进行监测、控制或记录，例如，大厅、街道、城镇的某个角落、国家的某个地点甚至是世界的任何地方。

借助互联网的力量，使远程监控成为现实。

对于基于以太网并具备联网能力的仪器，只要在智能手机有信号的地方，就可以随时随地实现远程访问。

无论是最简单的应用，例如在iPhone、黑莓设备或笔记本电脑上通过web 浏览器查看数据；还是较复杂的应用，例如在发生报警时发送短信或电子邮件，或是通过互联网从远程位置向中心办公室传输数据日志文件。

只要能够接入互联网，用户就可以全天候、随时随地访问这些数据。

基于以太网的系统中内建的被动监控功能确实为工作安全带来了新的含义。

您可以对过程测量和控制系统完全放心：无论它们多么庞大，都可以保持最佳运行状态。

为什么怎么说呢？使用web 浏览器就可以对此一目了然。

现在许多仪器都可以将数据记录到SD 卡中，这些数据可以在PC 或Mac 上直接读取，或者通过以太网或互联网远程下载。

为了帮助您了解这些设备的功能，请设想以下应用场合：监控公司仓库的内部环境。

您需要监控（和记录）温度、湿度，甚至安全程度。

借助一些独立的设备，例如内置传感器的iSD-TH，无需现场派驻人员即可对温度、湿度甚至露点进行监测。

通过将两个闭合触点与普通报警传感器配合使用，如果出现门被打开、窗户被打破或者自动喷水灭火系统启动等状况，就会发出警报。

iSD-TH可以向您和邮件列表中的用户发送电子邮件，还可以向您的手机发送短信。

如果使用IP 摄像机或网络摄像头，可以在计算机上直接查看现场画面。
