Emerson Introduces New Generation of High Temperature pH Sensors
Emerson Process Management (Irvine, CA, USA) has introduced a new generation of high temperature sensors designed specifically for increased sensor life and greater performance in elevated temperature applications. The new generation PERpH-X™ line of Rosemount® Analytical Models 3300HT and 3400HT high temperature pH sensors perform longer in temperatures up to 145°C (293°F).
The Models 3300HT and 3400HT are the first releases of an entirely new sensor platform with specialised design features that include the following:
John Wright, Vice President of Marketing, Rosemount Analytical Liquid Division of Emerson Process Management, commented: "The innovative new design behind the new generation high temperature PERpH-X sensors Models 3300HT and 3400HT establishes a new benchmark for performance and life in elevated temperature environments. Testing at 145°C indicated that the PERpH-X outperformed the competition in response time, sensor lifetime and accuracy. While customers will seldom need to use the sensors at these levels, we wanted to demonstrate the significant long life potential of these new sensors in real-world applications, such as pulp and paper and chemical processing.
"Over the last 65 years, Emerson has consistently offered new standards in long life, high performance, low maintenance, and high accuracy analysis equipment. Our new generation of high temperature sensors perform longer than previous technologies in elevated temperatures, offering further proof of Emerson's technology leadership."
The Models 3300HT and 3400HT are recommended for use not only at high temperatures, but also in harsh, dirty and abrasive applications such as lime slurry, paper machine headbox, pigments and dyes and other applications where suspended solids are present. They feature pressure/temperature ratings of 100 psig at 145°C or 250 psig at 100°C. The sensors come with several mounting and cabling options, including Variopol connectors. The Model 3400HT retractable design allows for the sensor to be removed from the process for calibration and maintenance without process shutdown. The Model 3300HT insertion/submersion design allows for variable insertion depths and simple sensor removal without cable twisting. The PERpH-X sensors allow continuous measurement of diagnostics to indicate when cleaning or sensor replacement is necessary.
The Rosemount Analytical liquid measurement technology is a key component of Emerson's PlantWeb® digital plant architecture that delivers operating efficiency improvement.
