유도식 (Torodial, Electrodeless) 전도도 센서 ISC40

전도도 측정에 사용되는 두 가지 기본 센서 스타일이 있습니다. : 접촉식 과 유도식 (Toroidal, Electrodeless).

유도식 전도도 (Toroidal 또는 Electrodeless라고 부름)를 사용하면 유도형 센서의 감지 요소(전극 코일) 가 공정과 직접 접촉하지 않습니다. 이 두개의 일치된 (동일한) 코일은 PEEK (또는 테프론) 에 캡슐화되어 공정의 악영향으로부터 보호합니다.

유도식 센서 ISC40에는 셀계수(상수)가 하나만 있습니다. 전도도 측정 범위는 거의 50-2,000,000 µS/cm입니다. 낮은 전도도(50 µS이하) 에서만 센서의 정확도가 떨어집니다.

유도식 센서 ISC40는 사실상 유지보수가 필요 없습니다.

해당지역에 따라 ISC40G/ISC40S 시리즈 또는 ISC40GJ/ISC40SJ 가 제공됩니다. 

헹굼 물 또는 농축산에서 측정 한 전도도 값에 대한 정확도는 판독 값의 0.5 % + 0.5 microS/cm입니다. 외부 재질은 열악한 산업 조건에서 장수명을 보장합니다.

불소 산 또는 산화 농축 산을 제외한 모든 용액에서 내 화학성이 우수한 내식성 / 내마모성 PEEK (폴리 에테르 에테르 케톤)로 되어 있습니다. 내 약품성의 궁극적인 재료는 플루오르 화 수소산 및 농축산 (질산, 황산, 발연)의 산화를위한 PFA (테프론)입니다.

SC40G 및 ISC40은 일반용으로 PEEK (센서 유형 GG)로 제공됩니다. PEEK에 대해 샘플이 공격적인 애플리케이션에서는 테플론 (센서 유형 TG)에 센서를 제공합니다.

 

ISC40 센서에는 견고한 스테인레스 스틸 장착 나사, 너트 및 개스킷이 함께 제공되어 대량 헤드 설치 기술을 사용하여 설치 유연성을 극대화합니다. 또한 센서의 오랜 수명을 위해 이중 O- 링 씰을 사용하여 신뢰할 수있는 인라인 또는 오프라인 설치에 사용할 수있는 다양한 홀더 및 옵션이 있습니다. 추가 모델은 볼 밸브 삽입 어플리케이션 프로그램 및 위생 플랜지 설치 시에 사용할 수 있습니다.

두 센서 모두 파울 링 프로세스에 대한 최적의 내구성을 위해 큰 보어를 가지며, 적절하게 설치되면 유량이 센서를 깨끗하게 유지하여 측정 오류를 방지합니다.

Depending on your region there are different versions of the holders available. 

ISC40FF/ISC40FS/ISC40FD Holders 

This program includes flow fittings and their subassemblies for in-line or direct mounting of conductivity sensors in piping systems. A wide choice of construction materials gives the user the best solution for any process considering chemical resistance, pressure and temperature specifications.

  • Wide choice of construction materials.
  • High degree of standardization to all cells.
  • Easy mounting, service and removal or replacement of sensors.

  • Available with flange adapters.

Model PR10 Retractable "Hot-Tap" Holder

On-line measurements often present extra challenges, especially when routine maintenance is required. The PR10 is ideally suitable for applications where the sensors must be removed without interrupting or shutting down the process. Without any special tools the PR10 can be retracted safely from the process at pressures up to 5 bar (72 psi). The PR10 is a universal retractable assembly that can be used for all liquid measurements. The PR10 is designed to accept any commercially available pH/ORP or dissolved oxygen sensor that has a PG13.5 connection while still being backwards compatible with old Yokogawa electrodes.

For ease of use optional flush ports are available. In the retracted position the sensor can be kept moist, cleaned or even calibrated. This can all be done without process interruption or disassembly of the armature.

  •  One model for pH/ORP, dissolved oxygen, conductivity and inductive conductivity sensors
  • All commercially available pH electrodes, such as PG13.5, SMART sensors, Vario Pin, YEF and DIN connectors can be installed in the PR10.
  • Integrated protection cage
  • A "scraper" is built-in to each assembly to effectively scrape or wipe off the
    process from the PR10's shaft as it is being retracted from the process.
  • A safe "through the valve" insertion and retraction design
  • Simplified installation by optional ball valves with flanged or tapered connections
  • Optional flush port accessories makes it easy to keep sensors moist (pH) and clean, and also provides access for calibration if desired.

Calibration Standard Solutions

Yokogawa supplies Hamilton conducctivity standars whose stability of ±1% is guaranteed over a life cycle of 1 to 3 years, depending on the value.

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:

Control of sodium chloride (NaCl) concentration at a salt dissolver where solid salt is dissolved in water, is highly important because of the electrolysis efficiency. A conventional way of measuring the concentration of supersaturated NaCl solution had been performed by using non-contact type sensors (e.g., γ-ray density meter) since NaCl, impurities, and precipitates are in the solution.

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.
