4、仪表的核心采用高性能单片微电脑处理器，用 A/D 转 换进行精确的电极阻值测试，在此基础上实现了高可靠的水位智能识别，并具有电极测试、电极失 效告警等辅助功能。 As a new intelligent electrical-contact liquid level monitoring instrument with high reliability, this intelligent liquid level instrument is intelligently updated under the precondition of keeping the compatibility wit
5、h traditional electrical-contact liquid level instruments. Specifically, high-performance microcomputer processor is adopted as the core of this instrument, and A/D conversion is adopted for accurately measuring electrode resistance, thus to realize highly reliable and intelligent water level identi
6、fication and such functions as electrode testing and electrode failure alarm. 另外，本仪表还具有多项传统仪表所没有的高级功能：标尺数字和告警点位置可以自由设置、 并具有 4-20mA 电流输出、RS485 通信接口等。 Additionally, this instrument has multiple advanced functions that are not configured in traditional instruments, namely: free setting of scale figure
7、and alarm point, 420mA current output, RS485 communication interface, etc. 高度的容错性高度的容错性 Strong fault-tolerant property 由于采用了智能水位识别技术智能水位识别技术，在部分电极损坏的情况下仍能得到正确的水位，并且立即将 电极损坏情况在面板标尺上显示出来。 Due to the adoption of intelligent water level identification technology, correct water level value can be still o
8、btained under the condition that part of the electrode is damaged and meanwhile the damage condition of the electrode can be immediately displayed on the scale plate of the panel. 高抗干扰能力高抗干扰能力 Strong interference immunity capability 电极测试部分采用了光电隔离和数字滤波数字滤波技术，并采用带回差的电极带回差的电极状态判别法状态判别法，大大提高 抗干扰能力；输出环节采
9、用延迟告警延迟告警，防止在瞬间强干扰的情况下产生误告警，同时彻底解决了老 式仪表在开机瞬间产生误告警的问题。 Optoelectronic isolation technology and digital filtering technology are adopted for electrode testing part, and meanwhile the electrode state judgment method with return difference is also adopted, thus to significantly improve the interference
10、 immunity capability; delayed alarm is adopted for the output link in order to prevent false alarms from being generated at the strong interference moment and accordingly completely solve the problem of the generation of false alarm at the startup moment of old instruments. 高可靠性高可靠性 High reliability
11、 除上面提到的电极容错技术电极容错技术和抗干扰能力外，仪表本身由超大规模集成电路构成，电路设计 简捷，硬件可靠性很高。 Besides the electrode fault-tolerant technology and interference immunity capability mentioned above, this instrument also has the features of super-large-scale integration composition, convenient and simple circuit design, and high hardwar
12、e reliability. 标尺数字和告警点可设定标尺数字和告警点可设定 Configurable scale figure and alarm point 可以自由设置水位标尺数字和告警点位置，非常灵活直观。 The scale figure and the alarm point of water level can be freely set, thus to make this instrument have the features of flexible setting and visual display. 电极测试功能电极测试功能 Electrode testing func
13、tion 老式仪表只有当电极已损坏时才可以被发现，而电极的损坏往往是一个缓变过程（如结垢、 腐蚀等）。本仪表能对每一个电极单独进行测试，测出电极对测量筒体的电阻，这种测试可以使您 及时发现异常的电极， 或帮助您决定一组电极是否需要清洗或更换， 也可为水汽阻临界值的调整提 供参考。 For the old instruments, only the damaged electrode can be discovered, but the electrode damage process is a slow change process (including scaling, corrosion,
14、 etc.). This instrument can independently test each electrode, namely testing the resistance of the electrode relative to the measuring barrel, and such test can make you timely discover abnormal electrode, or help you to decide whether this group of electrodes shall be cleaned or replaced, or provi
15、de the reference for the adjustment of the critical value of water 2. due to the adoption of trimmer potentiometer for adjustment, it is difficult to operate and it is not easy to adjust to the optimal value. For the above two reasons, the adjustment of the critical value is blind, so if the field e
16、nvironment is slightly changed, the critical value must be usually readjusted. 而本仪表由于具有“电极测试”功能，可以测出水、汽阻，由此可以确定出一个比较合理的临界 值。调整临界值用按键操作，数码显示，方便直观且精确，可调范围也较宽，在 10K 1000K 之 间。 This instrument is provided with the “electrode testing” function and can measure water resistance and vapor resistance, so a r
17、elatively rational critical value can be determined. The critical value can be adjusted through keys operation and digitally displayed, so such adjustment is convenient, visual and accurate. Additionally, the critical value can be adjusted in a relatively wide range, namely 10K1000K. 与老仪表的另一重大区别是：水汽
18、阻的临界值，即“水”和“汽”的分界线有两条，一条是“最大 水阻值”（以下简称“水阻”），一条是“最小汽阻值”（以下简称“汽阻”），认为阻值小于“水阻”的电 极浸在水中，阻值大于“汽阻”的电极在水面之上，而阻值介于“水阻”和“汽阻”之间的电极保持原来 的状态不变。这种方式类似于数字电路中的“施密特比较器”，能大大提高抗干扰能力。 Another major difference with the old instruments is: for the critical values of water after obtaining these resistance values, the mic
19、rocontroller firstly employs digital filtering program to filter out interference, and then the intelligent water level identifying program is used to identify the present water level, and finally the water level value is displayed by the scale plate and the digital display on the panel. Therein, if
20、 the water level exceeds the preset upper and lower limits, then corresponding sound-light alarm will be sent out and meanwhile the corresponding alarm output will be triggered. Please pay attention to the following details: in order to prevent false alarm, the alarm will not be sent out at the mome
21、nt that the water level exceeds the limit, but will be sent out after the water level stably exceeds the limit for a certain period, and this is the delayed alarm mentioned above. 在智能水位识别程序智能水位识别程序识别水位的同时， 也将一些“表现异常”的电极识别出来， 并使面板标尺上 的相应点闪烁以提醒维护人员注意。 When the intelligent water level identifying progr
22、am identifies water level, some “abnormal” electrodes will be also identified and will make the corresponding point on the scale plate of the panel flicker in order to remind the maintenance personnel. 如果将水阻测试电路测试出来的阻值直接在数码显示器上显示出来，就可以知道电极的使用 情况，这就是电极测试电极测试功能。 If the resistance value measured by the
23、 water resistance testing circuit is directly displayed on the digital display, then the operator can know the use condition of the electrode, and this is namely the electrode testing function. 外部接口提供 4-20mA 电流输出和 RS485 通信等对外接口功能，用于一些高级应用，如连接 DCS 系统、人机界面、工控组态软件等。 The external interface has such func
