Pure Water (Low) Conductivity Sensors SC4A/SC42

In pure water applications, the accuracy of measurements is strongly influenced by temperature variations, polarization effects at the surface of the electrodes, and cable capacitances. 

Yokogawa’s SC42 and SC4A contacting conductivity sensors are available from a combination of FDA-approved wetted materials, making them ideal for the monitoring of pure water systems used in the preparation of injectable solutions.

The SC42 and SC4A are also ideal for use in many low conductivity applications including:

  • Semiconductor
  • Power
  • Pharmaceutical

Overview:

Yokogawa’s conductivity transmitters and converters possess USP functions that make this seemingly complex and troublesome requirement pain-free and automatic.

Overview:

There are many points in the processing of edible fats and oils that benefit from the use of analytical measurements. Inductive conductivity, contacting conductivity, gas density, and pH can be utilized to increase the quality of the end product, as well as protecting expensive processes.

Overview:

To defray energy costs, many industrial plants have their own boilers to generate steam to produce a portion of their energy needs. In addition to generating power, the steam may also be used directly in plant processes or indirectly via heat exchangers or steam jacketed vessels. 

Overview:

Clean-in-place (CIP) is the system designed for automatic cleaning and disinfecting in the food & beverage, pharmaceutical, and chemical industries. Tanks and piping are cleaned and sterilized with various cleaning solutions, fresh or hot water, or steam after manufacturing products is completed.

Overview:

Ion Exchange is a method for the exchange of ions between two electrolytes or between an electrolyte solution and a complex molecule. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic ion exchangers.
