Description:

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.……

Description

Percent Concentration Analyzer ISC450G

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.
