DC4000型电导率控制仪是基于微处理器的电导率控制仪, 其设计可成用于各种需要精确控制总溶解固体和化学药剂投加 的水处理应用的形式。DC4000型电导率控制仪可以控制冷却 塔、锅炉和闭环系统的电导率和化学药剂投加就是许多应用中 的几种。
化学药剂投加可基于以下四个方面: ·具有锁定(限制)功能的投加和排放。 ·作为排放的百分比进行投加。 ·作为时间的百分比进行投加。 ·配有计数器的外部起动的装置。
因为流量计接线没有极性,所以输入可以颠倒。 输入到接线端子位置TB9-1。 输入到接线端子位置TB9-2。
流量开关输入: 该输入可用来连接一个提供开关闭路输出的流量开关或其
它设备。如果象这样的设备连接到DC-4000型控制仪,当该开 关处于“打开”位置时,其将起断开控制的作用。
8
该功能可用作一个安全过载,以避免给定条件下的控制作 用,如丧失流量。当使用流量开关(或其它设备)时,仅有继 电器电源被切断。仪器仍将显示现在的电导率,并可以充分使 用键盘。

MAN, PRG, MIO,COM, OP2, AL2, AU1 and AU2Com indicators is non-applicable.OP1 and AL1 will indicate I/O operation of the corresponding module.Basic display status:When power on, the upper display window of the instrument shows the process value (PV), and the lower window shows the set-point (SV). This status is called basic display status.When the input signal is out of the measurable range (for example, the thermocouple or RTD circuit is break, or input specification sets wrong), the upper display window will alternately display “orAL” and the high limit or the low limit of PV, and the instrument will automatically stop output. If the lower display window alternately display “HIAL”, “LoAL”, “HdAL” or “LdAL”, it means high limit alarm, low limit alarm, deviation high alarm, and deviation low alarm happening.OPERATION DESCRIPTIONz Set Value Setting:In basal display status, if the parameter lock “Loc” isn't locked, we can set setpoint (SV) by pressing 、 or . Press key to decrease the value, key to increase the value, and key to move to the digit expected to modify. Keep pressing or , the speed of decreasing or inscreasingvalue get quick. The range of setpoint is between the parameter SPL and SPH.The default range is 0~400.z Parameter Setting:In basal display status, press and hold for about 2 seconds can accessField Parameter Table. Pressing can go to the next parameter; pressing 、 or can modify a parameter. Press and hold can return tothe preceding parameter. Press (don't release) and then press key simultaneously can escape from the parameter table. The instrument will escape auomatically from the parameter table if no key is pressed within 30 seconds. Setting Loc=808 and then press can access System Parameter Table.●AI artificial intelligence control and auto tuningWhen AI artificial intelligence control method is chosen (CtrL=APId), the PID parameters can be obtained by running auto-tuning. In basal display status,press for 2 seconds, the “At” parameter will appear. Press to changethe value of At from “oFF” to “on”, then press to active the auto-tuning process. During auto tuning, the instrument executes on-off control. After 2-3 times of on-off action, the instrument will obtain the optimal control parametervalue. If you want to escape from auto tuning status, press and hold thekey for about 2 seconds until the "At" parameter appear again. Change “At”from “on” to “oFF”, press to confirm, then the auto tuning process will be cancelled.Note 1: If the setpoint is different, the parameters obtained from auto-tuning are possible different. So you’d better set setpoint to an often-used value ormiddle value first, and then start auto-tuning. For the ovens with goodheat preservation, the setpoint can be set at the highest applicabletemperature. Depending on the system, the auto-tuning time can befrom several seconds to several hours.Note 2: Parameter Ctl (on-off differential, control hysteresis) has influence on the accuracy of auto-tuning. Generally, the smaller the value of Ctl, thehigher the precision of auto tuning. But Ctl parameter value should belarge enough to prevent the instrument from error action around setpointdue to the oscillation of input. Ctl is recommended to be 2.0.Note 3: The instrument has the function of self-learning. It is able to learn the process while working. The control effect at the first run after auto tuningis probably not perfect, but excellent control result will be obtained after aperiod of time because of self-learning.10OMEGA’s policy is to make running changes, not model changes, whenever an improvement is possible.

分析电导率仪的按键说明和使用方法 电导率仪如何做好保养
分析电导率仪的按键说明和使用方法电导率仪如何做好保养为了让大家能够正确的使用电导率仪,我特意为您整理了认真的电导率使用方法。
首先在使用电导率仪前,我们应了解设备各个按键的作用,以便下一步更好的使用,以下为了让大家能够正确的使用电导率仪,我特意为您整理了认真的电导率使用方法。
首先在使用电导率仪前,我们应了解设备各个按键的作用,以便下一步更好的使用,以下是电导率仪的紧要按键及功能说明:1、电极常数:按此键快速设置和查看电极常数2、温补系数:按此键设置和查看温补系数3、确定:按此键接受设置4、测量:按此键回到测量状5、滚动(▼,▲):可用来更改测量方式中的人工温度设置和更改电极常数和温补系数再了解电导率仪的使用方法:1、未开电源开关前,察看表针是否指零,如不知零,可调整表头上的螺丝使表针指零。
2、将校正、测量开关扳在“校正”位置。
3、插接电源线,打开电源开关,并预热数分钟(待指针完全稳定下来为止)调整“调正”器使电表满度指示。
4、当使用(1)~(8)量程来测量电导率低于300 的液体时,选用“低周“,这时将板向“低周“即可。
当使用(9)~(12)量程来测量电导率在300 至范围里的液体时,则将扳向”高周“。
5、将量程选择开关扳到所需要的测量范围,如预先不知被测溶液电导率的大小,应先把其扳在最大电导率测量档,然后逐档下降,以防表针打弯。
6、量读数:一般的测量其“常数”的旋钮都打到1.0档,测量前调正(ADI)旋到最大值,然后再渐渐地调整,把测量开关打到校正档调好零点,选好量程,再把测量开关打到测量的位置然后再读数。
7、电极的使用:使用时用电极夹夹紧电极的胶木帽,并通过电极夹把电极固定在电极杆上。

电导率仪使用说明书
一、 原理电导率是以数字表示溶液传导电流的能力。
水的电导率与其所含无机酸、碱盐的量有一定的关系,当它们的浓度较低时,电导率随着浓度的增大而增加,因此,该指标常用于推测水中离子的总浓度或含盐量。
电导(G )是电阻(R )的倒数。
因此当两个电极(通常为铂电极或铂黑电极)插入溶液中,可以测出两电极间的电阻R 。
根据欧姆定律,温度一定时,这个电阻值与电极间距L (cm )正比,与电极的截面积A (cm 2)反比,即R =ρ×AL其中ρ为电阻率,是长1cm ,截面积为1cm 2导体的电阻,其大小决定于物质的本性。
据上式,导体的电导(G )可表示成下式:G =R 1=ρ1×L A =K ×J1其中,K=1/ρ称为电导率,J =L /A 称为电极常数电解质溶液电导率指相距1cm 的两平行电极间充以1cm 3溶液时所具有的电导。
由上式可见,当已知电极常数(J ),并测出溶液电阻(R )或电导(G )时,即可求出电导率。
二、 CON-2A 电导率仪的特点CON-2A 型电导率仪是实验室测量水溶液电导率必备的仪器,它广泛应用于石油化工生物医药污水处理环境监测矿业冶炼以及大专院校和科研单位等。

电导率仪的使用方法和电导率仪工作原理之欧阳体创编
电导率仪的使用方法和电导率仪工作原理一.电导率仪的概念电导率:水的导电性即水的电阻的倒数,通常用它来表示水的纯净度。
电导率是物体传导电流的能力。
电导率测量仪的测量原理是将两块平行的极板,放到被测溶液中,在极板的两端加上一定的电势(通常为正弦波电压),然后测量极板间流过的电流。
根据欧姆定律,电导率(G)电阻(R)的倒数,是由电压和电流决定的。
二.电导率仪的单位电导的基本单位是西门子(S),原来被称为姆欧,取电阻单位欧姆倒数之意。
因为电导池的几何形状影响电导率值,所以标准的测量中用单位S/cm来表示电导率,以补偿各种电极尺寸造成的差别。
单位电导率(C)简单的说是所测电导(G)与电导池常数(L/A)的乘积.这里的L为两块极板之间的液柱长度,A为极板的面积。
=ρl=l/σ(1)定义或解释电阻率的倒数为电导率。
σ=1/ρ ;(2)单位: 在国际单位制中,电导率的单位是西门子/米,其它单位有:s/cm,us/cm。
1S/m=0.01s/cm=10000us/cm;(3)说明电导率的物理意义是表示物质导电的性能。
电导率越大则导电性能越强,反之越小。
三.电导率的测量原理引起离子在被测溶液中运动的电场是由与溶液直接接触的二个电极产生的。
此对测量电极必须由抗化学腐蚀的材料制成。
实际中经常用到的材料有钛等。
由二个电极组成的测量电极被称为尔劳施(Kohlrausch)电极。
电导率的测量需要弄清两方面。
一个是溶液的电导,另一个是溶液中1/A的几何关系,电导可以通过电流、电压的测量得到。
这一测量原理在当今直接显示测量仪表中得到应用。
而K= L /AA——测量电极的有效极板L——两极板的距离这一值则被称为电极常数。
在电极间存在均匀电场的情况下,电极常数可以通过几何尺寸算出。
当两个面积为1cm2的方形极板,之间相隔1 cm组成电极时,此电极的常数K=1cm1。
如果用此对电极测得电导值G=1000μS,则被测溶液的电导率K=1000μS/ cm。

5.0 启 动
DC-4000型控制仪能够为各种工艺要求进行编程。在完成 启动以前,必须根据控制仪编程确定某些参数。应该提前完成 下面的工作单,以帮助控制仪的编程。
一个最重要的问题是控制仪是否将用于冷却塔、锅炉或闭 环控制。如果运行的不是冷却塔或连续取样的锅炉,则设定菜 单将用来选择闭环系统的下降断开点,或选择锅炉方式。

上时,电极应安装到旁通回路中,如图6所示。 电极必须接触到活动的、有代表性的系统水样。电极应该
安装成使得其可以从装配三通上水平取下来的位置。水样应该 从底部流进,从顶部流出。这样安装可确保装有电极的三通在 系统流动时处于充满水的状态,避免电极形成空气隔。
在电极两侧安装截止阀非常有必要,这样在系统流动时可 以取下电极。建议还要使用取样水嘴和过滤器。化学药剂可以 直接投加到旁通管中,但必须在电极的下游。这同样需要在两
用于流量开关输入的连接端子是端子TB9-3和TB9-4。该接 线没有极性,所以引线可以颠倒。如果不用流量开关,则必须 安装跳线。 注意:在安装控制仪期间,所有仪器,包括预装线的型号、辅助 件项如流量计、流量开关报警等,必须将线连接到端子板上。

流量开关输入: 该输入可用来连接一个提供开关闭路输出的流量开关或其
它设备。如果象这样的设备连接到DC-4000型控制仪,当该开 关处于“打开”位置时,其将起断开控制的作用。

该功能可用作一个安全过载,以避免给定条件下的控制作 用,如丧失流量。当使用流量开关(或其它设备)时,仅有继 电器电源被切断。仪器仍将显示现在的电导率,并可以充分使 用键盘。

DC-4000型电导率控制仪有115VAC或220 VAC两种规格。 220 VAC的规格提供了一个六脚带地线的交流电源线和PG-9防 液体接头。两种配置都提供了一个四针接头,用于电导率测头 输入。 注意:DC-4000型电导率控制仪提供了一个电压选择器开关, 以便仪器能使用115VAC或220 VAC两种电源。为转换电压,应 先断开仪器电源,并取下前面板。选择器开关位于电路板的变

2.0 安 装
2.1 装配控制仪壳体 DC-4000型电导率控制仪配有内部式的墙壁装配凸缘,其
应安装在没有震动的位于人眼部高度的位置。所有可用的装配 孔都应使用上。
当使用预先穿孔的选用件时,壳体由NEMA 12X成形制造。 如果与防水的导线管连接,其能够由NEMA 4X成形制造。下面的 间距可以确保安装的顺利进行:
DC-4000系列电导率控制仪的一般操作显示是电导率读值 显示屏(如上所示),该显示屏在整个手册中都作为“系统运 行”(system run)。控制仪继电器输出不能启动除非仪器处 于“系统运行”或电导率读值方式。仅有的例外是当仪器处于 测试方式中。
在观察或改变电导率控制仪编程后,仪器必须返回到“系 统运行”或电导率读值方式,以便能进行自动控制。有三种方 法可以返回到“系统运行”显示屏: 1.使用“∧”或“∨”键在各种菜单之间移动,并返回到“系 统运行”显示屏。 2.同时按下任意两个键,可使仪器立刻返回到“系统运行”显 示屏。 3.在15分钟以后,仪器将自动返回到“系统运行”显示屏。
4.1 主菜单项 (1)电导率:
在启动时控制仪总是显示该项目,以及除去按键面板处于 使用状态的所有时间。
该主菜单项及其子程序可进行入下工作: ·观查电导率读数值。 ·改变(标定)电导率读数值。
(2)设定值:
该主菜单项及其子程序可进行入下工作: ·观查和改变电导率设定值。 ·观查和改变偏差值(回差值)。 ·观查和改变高限和低限电导率报警设定。
