FU20/FU24/PH20一體化pH/ORP (REDOX)傳感器

PH20/FU20/FU24一體化傳感器體現了橫河電機如何將“簡單即最好”這句格言應用於傳感器技術。這些傳感器的特點在於具有四個獨立的元件(pH、參比、溫度、ORP),可以使用耐用的Ryton或PVDF (FU20)傳感器、Ryton (FU24)或PVDF (PH20)傳感器同時測量pH和ORP。集成或Vario-Pin電纜採用數字編碼電纜,同時傳感器上採用的整體式NPT螺紋,便於安裝。通製FU20的快速釋放適配器,可以輕鬆拆卸傳感器進行清潔和標定。

FU20組合傳感器體現了橫河電機如何將“簡單即最好”這句格言應用於傳感器技術。寬體傳感器(外徑26 mm)具有四個獨立的元件,包含在堅固的PPS40GF (RytonTM)或PVDF本體中。使用集成工業3/4"錐螺紋可輕鬆安裝。利用大容量凝膠電解質和雙接合點參比系統減緩消耗和污染,從而延長了使用壽命。該系統針對通製簡化可實現準確和可靠的pH值或氧化還原測量的應用。這意味著在90%的已知應用中,該傳感器將是一個理想的選擇。

FU24是一款一體化pH/ORP傳感器,採用耐化學腐蝕的PPS 40GF本體,適用於惡劣的pH應用,尤其適用於壓力或溫度波動的應用。由於製程流體在頻繁的壓力或溫度波動的影響下進出傳感器,因此這些製程會縮短傳感器的使用壽命。這就導致參比電解質快速脫鹽和稀釋,進而改變參比電壓,最終導致pH值測量漂移。

通製將成功獲得專利的橫河電機波紋管設計理念融入FU24電極,創建了一種強大的壓力補償機制。內定波紋管確保內部壓力立刻與外部壓力保持平衡,使傳感器幾乎不受外部壓力波動的影響。波紋管張力引起輕微超壓,可以防止流體進入,並保持陽離子從傳感器流出。

由於可以對製程溫度和壓力變動進行補償(已獲專利),因此PH20被叫作“Tempress”。通製這一簡單的機械特性,傳感器更加精確且使用壽命變長。補償面板可以彎曲以適應變化,避免隔膜壓差製大。這可以避免大多數冷端的相關問題。PH20由耐化學腐蝕的PVDF制成。參比系統的材質為銀/氯化銀,具有雙接合點和凝膠電解質,以消除污染。鉑氧化還原電極具有雙溶液接地,對於嚴格的精度和傳感器診斷測量至關重要。

摘要:

Wet scrubbers are used in utilities, paper mills, and chemical plants to remove sulfur dioxide (SO2) and other pollutants from gas streams. Undesirable pollutants are removed by contacting the gases with an aqueous solution or slurry containing a sorbent. The most common sorbents are lime, Ca(OH)2, and limestone, CaCO3

For control of batch neutralization, a pH measurement coupled with a timer-controlled chemical feed scheme provides very satisfactory results.

This system can be adapted for either acid waste or alkaline waste neutralization.

摘要:

The term "cooling tower" is used to describe both direct (open circuit) and indirect (closed circuit) heat rejection equipment. Cooling towers are heat-transfer units, used to remove heat from any water-cooled system. The cooled water is then re-circulated (and thus, recycled) back into the system. Since the process water is re-circulated, the mineral concentration increases as a result of the evaporation.

摘要:

Process liquid analyzers such as pH meters, conductivity meters, ORP meters, and density meters play an important role at electrolysis plants in the control of concentrations of various process solutions. This requires both precision and stability under harsh conditions that include highly corrosive substances, high temperatures, and many impurities.

摘要:

Most zinc are produced at hydrometallurgically, where a high-grade zinc product can be obtained and valuable metals mixed in the raw material can be recovered. In the hydrometallurgy, the raw material of zinc concentrate is roasted and then dissolved in sulfuric acid to remove impurities. The process called leaching and pH control of the leachate is important.

摘要:

Wastewater from electroplating facilities and certain types of chemical plants contains toxic forms of hexavalent chromium such as chromate and dichromate. The hexavalent chromium in this wastewater must be reduced before the water can be discharged. This requires a two-step process: hexavalent chromium (CR6) is reduced to trivalent chromium (CR3); and CR3 is precipitated as chromium hydroxide.

摘要:

Power plant boiler houses designed to burn coal or high sulfur oil are required by Federal and State pollution regulations to "scrub" (remove) sulfur dioxide from flue gasses to meet emission limits. SO2 in flue gasses is known to be harmful to the environment, as it is one contributor to the formation of acid rain. pH control is critical for the proper functioning of the scrubber system.

摘要:

Fish perform all their bodily functions in water. Because fish are totally dependent upon water to breathe, feed and grow, excrete wastes, maintain a salt balance, and reproduce, understanding the physical and chemical qualities of water is critical to successful aquaculture. To a great extent water determines the success or failure of an aquaculture operation.

摘要:

Current trend for increasing mercury awareness throughout the public sector has caused the government to take action. Recently, the Environmental Protection Agency (EPA) has focused their efforts on controlling mercury levels produced in various coal fired power plants. Based on information from several case studies, the EPA developed the Mercury and Air Toxics Standards to cut back mercury emissions. The most popular technology utilized by coal plants to meet the new standards is a scrubber which cleans the off gas from the combustion process. ORP sensors can further monitor the effluent from these scrubbers to ensure optimal mercury emission levels are achieved. By closely monitoring the mercury concentrations in the effluent, plant managers will be able to easily confirm their plants are meeting the EPA's standards.

產品簡介

    摘要:

    The FU24 is an all-on-one pH and ORP sensor made with a chemical resistant PPS 40GF body for harsh pH applications. It is particularly useful in applications with fluctuating pressure and/or temperature. These processes shorten sensor life because the process fluids move in and out of the sensor under influence of frequent pressure and/or temperature fluctuations. This results in fast desalting and dilution of the reference electrolyte which in turn changes the reference voltage causing a drifting pH measurement.
