유도식 (Torodial, Electrodeless) 전도도 분석계

전도도 측정을 위한 방법 중의 하나는 유도 전도도(Troidal 또는 Electrodeless)입니다, 이러한 유형의 측정에서는 센서의 감지 요소(전극 코일)는 프로세스와 직접 접촉하지 않습니다. 유도 전도도 방법은 특히 높은 전도도 측정에 적합합니다. 분석계는 2개의 Troidal 변압기가 내장된 센서와 함께 작동합니다. AC 전류는 공정 샘플에 전압을 유도하여 샘플에 전류를 발생 시킵니다. 이 전류의 세기는 옴의 범칙에 따른 샘플의 전도도에 비례합니다.

The ISC450 is designed to measure Specific Conductivity by using the Inductive Conductivity method. This method is especially suitable for high conductivity measurements. The analyzer works with a sensor with two toroidal transformers built in. An AC current induces a voltage in the process sample that results in a current in the sample. The strength of this current is proportional to the conductivity of the sample following Ohm's law.

The EXAxt 450 series builds on the superior functionality of the industry leading Yokogawa EXA series by enhancing the EXA's proven operation and application flexibility. The ISC450 features a unique accuracy and rangeability, which is only possible through superior sensor design and electronic data processing using a self tuning preamplifier with more than 10 sub ranges with automatic zero adjustment at every range change. Accurate concentration measurement requires accurate temperature compensation and the ISC450 offers three compensation methods from default NaCl compensation to user defined MATRIX compensation for electrolytes where the coefficient varies with Temperature and with Concentration.

The EXAxt is highly intelligent and continuously checks the software, hardware and sensor system for irregularities. Not only will these irregularities be signaled through the main display as well as a signal output according Namur NE43, the transmitter will provide adequate instructions how to solve the errors.

Overview:

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.

Overview:

In a semiconductor plant, a variety of chemicals are used in various manufacturing processes. The chemicals used for specific purposes are produced by diluting raw liquid with demineralized water using in diluting equipment, and the control of the concentration at this point is performed by conductivity measurement. 

Overview:

In the manufacturing process of Pharmaceutical, Chemical and Food & Beverage industries, the cleaning and sterilization of tanks and piping are done with various cleaning solutions, fresh or hot water and steam after manufacturing products. Clean-In-Place (CIP) is the system designed for automatic cleaning and disinfecting.

Overview:

In the past, the boiler feed tank systems in sugar factories had to be checked several times a day to make sure there were no sugar solution leaks. This was a very laborious process and, as continuous monitoring was not possible, monitoring results were not reliable. When a leak occurred, recovery operations were very costly and time-consuming.

Application Note
Overview:

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.
