Peek Sensor

Oct. 26, 2009
New materials introduced for 12mm disposable pH sensors said to improve durability and chemical resistance. Family of sensors includes glass as well as polyetheretherketone (PEEK) bodies.
Foxboro brand PH12 Series includes said to feature advanced diagnostics, fast response, long life and high accuracy and stability. "The 12 mm form factor is very popular, but users have not been able to take full advantage of many of the new developments that have improved the performance and longevity of pH sensors, especially the ruggedness and durability of PEEK materials together with flat membrane electrodes," said Joseph Downey, director, analytical product marketing for Invensys Operations Management. "The new PH12 family includes unique advances in sensor diagnostics, response time, accuracy and stability, all in a form factor that enables customers to improve their operations and control capability without needing to change mounting accessories."The PH12 sensor family is available in the PEEK or a glass body, either of which is available with a high-performing flat, ruggedized glass pH electrode or a domed pH electrode. Temperature performance range is from minus 15 C up to 125 C. A Nafion ion barrier in all PH12 family sensors protects the reference junction and a built-in, non-metallic (Kynar) solution ground, enables cost effective sensor diagnostics. Invensys is also offering a new selection of Foxboro FIT12 mounting accessories, including NPT, ANSI flange and sanitary versions with configurable dimensions, sensor protection and materials of construction. Foxboro PH12 sensors and accessories are available immediately.For more info, visit iom.invensys.com.
