Low alternating current is running between pump head (mass) and probe (electrode) (toavoid oxidation due to electrolysis). If the probe is not covered by product, theresistance between probe and mass is virtually infinite. As soon as product covers theprobe, a conductive connection is generated between probe and mass, the resistancechanges and current is conducted. This current activates an electric switching contactwithin the evaluation unit. 实现原理如下：泵头上安装探头，泵头和探头之间通低交流电（避免电蚀造成氧化）如果探头没被产品所覆盖它和泵头之间的电阻值几乎是极大的，一旦产品覆盖了探头它和泵体之间出现传导连接，电阻值改变电流被传导，电流驱动评测单元进行开关。Fig. 0 Alternating voltage is applied between probe (electrode) and pump head (mass). Assoon as the probe recognizes a change of concentration, alternating current is conducted,which activates a switching function in the electronic system. 探头和泵头之间通交流电，一旦探头探测到浓度的变化交流电被传导，驱动开关。Conclusion:结论Conductive measurement of conducting fluids is an efficient and safe measuringsystem for the detection of hose-diaphragm or flat diaphragm failure. FELUWA evaluation device FTW 570Z covers conductive ranges between 100 and 50k whilst FTW 325 covers ranges between 1 and 200 k.对传导液体传导性的测量，对于探测软管隔膜和平隔膜的故障来讲是一个有效，安全的系统。FELUWA评测单元FTW570Z 覆盖传导范围为100-50 k，FTW325覆盖传导范围为1-200 k3 / 21Illustration without hose-diaphragm and flat diaphragm failure: 软管隔膜和平隔膜无故障图：Fig. 1 Scheme of the measuring system Neither hose-diaphragm nor flat diaphragm failure. 软管隔膜和平隔膜均无故障。Hose-diaphragm and flat diaphragm are not damaged. 软管隔膜和平隔膜均无损坏。Probe 2 is measuring a certain resistance value of the conductive actuation fluid (glycol / water as per blue illustration).探头2测量一个传导性传动液的电阻值（图中蓝色液体乙二醇/水）Probe 1 is placed in a non-conductive fluid (hydraulic oil, brown illustration). 探头1放在一个无传导性的液体中（液压油，图中棕色部分）The slurry (yellow) is not in contact with the probes. Hence, there is no alteration ofresistance within the measuring system. 图中黄色的泥浆没有和探头接触，因此电阻值无变化。4 / 21Evaluation: Diagnostic of hose-diaphragm failure: 评测：诊断软管隔膜故障The FTW 570Z system is designed with two separate and independently operatingmeasuring circuits. FTW570Z系统设计为两条独立分开的测量电路。Measuring circuit 2 is set to the evaluation of hose-diaphragm failures (see below).

The hose-diaphragm is leaking. Probe 2 is measuring a changed resistance of the actuation fluid (glycol/water, blue illustration). Due to the mixture with slurry, this resistance is beyond / below the set value. Thus, an errorsignal is released at the FTW 570Z or FTW 325 system. 平隔膜没问题，软管隔膜泄漏。探头2测到驱动液中电阻值的变化（图中蓝色部分）由于其与泥浆混合，电阻值高于或低于设定值，因此FTW 570Z 或 FTW 325 会发出一个出故障的信号。5 / 21Evaluation: Diagnostic of flat diaphragm failure: 评测：诊断平隔膜故障：The FTW 570Z system is designed with two separate and independently operatingmeasuring circuits. FTW 570Z系统设计成为两个独立分开的测量电路。Measuring circuit 1 is set to the evaluation of flat diaphragm failures (see below).(Settings of evaluation unit FTW 570Z on page 7)电路1设定为评测平隔膜故障（如下）（设定见第七页）The FTW 325 system is designed for one measuring circuit each.(Settings of evaluation unit FTW 325 on page 9)FTW325设计为各自一个测量电路（设定见第九页）Fig. 3 Illustration of the measuring system with flat diaphragm failure平隔膜故障图The hose-diaphragm is alright. The flat diaphragm is leaking. Probe 1 is measuring achanged resistance of the hydraulic fluid (brown), which is beyond / below the setvalue. The set value results from test series and depends on the fluids used and theirconcentrations (see chart on page 16). Due to the mixture of hydraulic oil and actuation fluid (glycol/water), the electricresistance is decreasing or the electric conductivity is rising respectively. This change results in a signal at the FTW 570Z or FTW 325 system. 软管隔膜没问题，平隔膜泄漏。探头1测到液压油中电阻值变化大于或小于设定值。设定值是通过测试得出并根据液体的种类和浓度变化。（见16页表格）由于液压油和驱动液（乙二醇/水）混合，电阻减少或者电流传导性增加。这个变化使FTW 570Z 或FTW 325系统产生故障信号。6 / 21A) Settings of evaluation unit FTW570Z with Mono RackCasing FTW570Z评测单元设定The two-channel card design allows for the realisation of two switching points independent of each other.
