FU20/FU24/PH20一体化pH/ORP (REDOX)传感器

PH20/FU20/FU24一体化传感器体现了横河电机如何将“简单即最好”这句格言应用于传感器技术。这些传感器的特点在于具有四个独立的元件(pH、参比、温度、ORP),可以使用耐用的Ryton或PVDF (FU20)传感器、Ryton (FU24)或PVDF (PH20)传感器同时测量pH和ORP。集成或Vario-Pin电缆采用数字编码电缆,同时传感器上采用的整体式NPT螺纹,便于安装。通过FU20的快速释放适配器,可以轻松拆卸传感器进行清洁和标定。

FU20组合传感器体现了横河电机如何将“简单即最好”这句格言应用于传感器技术。宽体传感器(外径26 mm)具有四个独立的元件,包含在坚固的PPS40GF (RytonTM)或PVDF本体中。使用集成工业3/4"锥螺纹可轻松安装。利用大容量凝胶电解质和双接合点参比系统减缓消耗和污染,从而延长了使用寿命。该系统针对通过简化可实现准确和可靠的pH值或氧化还原测量的应用。这意味着在90%的已知应用中,该传感器将是一个理想的选择。

FU24是一款一体化pH/ORP传感器,采用耐化学腐蚀的PPS 40GF本体,适用于恶劣的pH应用,尤其适用于压力或温度波动的应用。由于过程流体在频繁的压力或温度波动的影响下进出传感器,因此这些过程会缩短传感器的使用寿命。这就导致参比电解质快速脱盐和稀释,进而改变参比电压,最终导致pH值测量漂移。

通过将成功获得专利的横河电机波纹管设计理念融入FU24电极,创建了一种强大的压力补偿机制。内置波纹管确保内部压力立刻与外部压力保持平衡,使传感器几乎不受外部压力波动的影响。波纹管张力引起轻微超压,可以防止流体进入,并保持阳离子从传感器流出。

由于可以对过程温度和压力变动进行补偿(已获专利),因此PH20被叫作“Tempress”。通过这一简单的机械特性,传感器更加精确且使用寿命变长。补偿面板可以弯曲以适应变化,避免隔膜压差过大。这可以避免大多数冷端的相关问题。PH20由耐化学腐蚀的PVDF制成。参比系统的材质为银/氯化银,具有双接合点和凝胶电解质,以消除污染。铂氧化还原电极具有双溶液接地,对于严格的精度和传感器诊断测量至关重要。

概述:

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.

概述:

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. (AN10B01B20-01E)

概述:

After extraction from sugar cane or sugar beets, juice must be purified to remove the many other organics and minerals that accompany it. The processing to accomplish this is heavily dependent on reliable pH measurement and control as illustrated.

概述:

There are a number of suppliers of oil and fat products used for edible purposes. These products include, but are not limited to olive oil, peanut oil, soybean oil, sunflower oil, lard, shortening, butter, and margarine. The raw materials for these products include animal by-products, fleshy fruits (palm and olive), and oilseeds. 

Industry:Food and Beverage

概述:

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.

概述:

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.

Industry:Chemical, Power

行业:
概述:

Cyanide-bearing wastewater from mining and electroplating facilities and certain types of chemical plants is toxic and must be treated by oxidation with chlorine or chloride to bring the cyanide concentration within regulatory limits.

Industry:Electrical and Electronics

概述:

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.

Industry:Electrical and Electronics

概述:

Removal of free oil and grease from a wastewater stream reduces the potential for equipment problems to occur further downstream. There are three forms of oil encountered in wastewater treatment at a refinery.

概述:

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.

概述:

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.

The lifetime of a pH sensor has a significant impact on the overall annual costs of a pH measuring loop. Optimizing four key factors will decrease these costs and optimize process control and overall plant efficiency.

概述:

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.

产品概述

    概述:

    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.
