UniCond Sensor Measures Conductivity of Water with Varying Purity Levels & Temperatures

UniCond Sensor

As the video below will show you, Mettler Toledo Thornton's UniCond sensors provide three significant advantages over other conductivity sensors:

1) Unmatched Accuracy - a self-contained measuring circuit which produces a robust output digital signal that is reliable over very long cable and certified factory calibration and temperature compensation with ASTM traceability stored in the sensor's internal memory to ensure highest installed accuracy out of the box.

2) Widest Rangeability - A single 2-electrode UniCond sensor can measure from ultrapure water all the way up to sea water with high accuracy. This significantly simplifies the specification, installation and spare parts inventory for water treatment systems. 4-electrode UniCond sensors cover the higher conductivity ranges of acid and base ion exchange regeneration chemicals.

3) Maintenance-free Performance - Mettler Toledo Thornton conductivity sensors for pure water provide high accuracy measurements with widely spaced electrodes that do not trap ion exchange resin particles, corrosion particles or bubbles, and yield more reliable, maintenance-free operation than with other sensors.

MCE Technology for Chloride and Sulfate Analyzers

Mettler Toldeo, under their Thornton brand, employs Microfluidic Capillary Electrophoresis in the on-line measurement of chlorides and sulfates. This measurement system delivers actionable measurements of these potentially harmful water constituents, enabling timely corrective action to be taken and prevent damage to turbines and other steam utilization equipment.

The MCE technology is currently available on Thornton's 3000CS  Analyzer which provides on-line measurements every 45 minutes. The system reduces cost of ownership and provides faster results than methods requiring sampling and off-line processing.

Intelligent Management for Process Sensors

Process analytical sensors can require scrupulous levels of attention and maintenance to continually deliver optimum performance. In some cases, overly frequent or involved maintenance is performed in order to avoid problems. Mettler Toledo, globally recognized leader in the development of process analytical sensors, developed a solution to streamline sensor maintenance and maximize reliability and performance.

The iSense software suite supports Mettler Toledo's line of intelligent sensors, monitoring and documenting sensor performance while maintaining real time indications of time to maintenance and calibration. Essentially, the iSense software provides guided sensor maintenance and continually verifies the operational health of the sensor to assure that delivered data is accurate and reliable.

There is much more to learn about how the iSense software and comprehensive offering of intelligent sensors can enhance process performance, as well as the efficiency of analytical operations.

Combining your process knowledge and experience with their product application expertise will yield an effective solution.

Improve Liquid Processing Performance With Sensor Technology

In the field of industrial processing, there is always a striving for improvement. Increasing output, improving output, and decreasing resource input are the watch phrases for process designers and operators in every industry.

Liquid processing often involves analytical instruments that produce periodic or continuous measurements of process conditions. The accuracy of these instruments will directly impact the quality and efficiency of the process, so great attention is paid to maintaining sensors and related instrumentation in top working order. Mettler Toledo, globally recognized leader in analytical sensor technology, provides a comprehensive solution for liquid analytical operations with its line of smart sensors and companion management software.

The ISM sensor technology couples the sensor with an onboard processor that continuously monitors sensor performance and delivers real time information about accuracy and time before maintenance. This empowers users to efficiently schedule maintenance tasks and operate with assurance that the data delivered by the sensor is reliable.

The video below sums up the ISM sensor benefits in under one minute. Share your process analytical challenges with application specialists and combine your process knowledge with their product application expertise to develop effective solutions.

New Dissolved Ozone Sensor

Mettler Toledo, under the Thornton brand, has released a dissolved ozone sensor employing the company's Intelligent Sensor Management technology that helps to streamline the use of sensors for measuring pH, conductivity, dissolved oxygen or ozone, and a host of other aspects of pure water. The pureO3 sensor technology provides rapid response in a sensor assembly with a built in digital measuring circuit and Intelligent Sensor Management (ISM®). The pureO3 is designed for monitoring low concentrations of dissolved ozone in semiconductor and pharmaceutical pure water samples, bottled water and similar applications. Minimal maintenance requirements and reliable long-term operation are hallmarks of this sensor.

How it works, in the company's own words...

"The pureO3 sensor uses a gas permeable membrane to separate the sample from the electrochemical cell inside. Ozone diffuses through the membrane in direct proportion to the partial pressure of ozone outside the sensor.The cathode and anode inside the sensor are polarized with a voltage to enable the electrochemical reaction of ozone. Ozone is reduced at the cathode while the anode is oxidized, producing a current in direct proportion to the amount of ozone present. The very low current developed by these sensors allows them to have a long life with low maintenance. An embedded temperature sensor enables temperature compensation to adjust for the changing permeability of
the membrane with temperature. In addition, the instrument uses the temperature value to convert the ozone partial pressure signal to a dissolved ozone concentration value by compensating for the changing solubility of ozone with temperature."

Benefits to the user from the ISM® based sensor.

• Full sensor identification by type and serial number.
• Calibration history with actual calibration, factory calibration, and last three calibration.
• Programmable timer to facilitate maintenance planning, reducing downtime.
• Starting calibration interval of 90 days.
• Time to maintenance function integrates ozone concentration over time, indicating replacement time for membrane body and electrolyte.
• Dynamic Lifetime Indicator for inner body used ozone concentration integration to predict life of inner body and membrane. Starting values, membrane body lifetime 180 days, inner body 1080 days.
• Sanitization counter allows the limit of ozone concentration and duration of sanitization cycleto be defined on the transmitter.

The pureO3 sensor with ISM operates with the M800 and M300 transmitters. ISM features enable users to maximize the lifetime of the sensors and minimize downtime by predicting when sensor maintenance is required.
