New Foxboro pH Sensor Line Doubles Service Life, Reduces Costs in Demanding Applications

12-Sep-2002
Foxboro, a unit of Invensys Production Management, has introduced a new family of sensors/order_t/'>pH sensors designed to improve operation in traditional problem areas within harsh process applications. As demonstrated at the Invensys Showcase Conference and EXPO, the new DolpHin(TM) sensor line incorporates patent pending measurement and reference technology that has proven to perform more than twice as long as traditional pH sensors in harsh applications. The new Foxboro pH sensor line also contributes to cost savings in maintenance and equipment by significantly reducing cleaning, calibrating, and replacement requirements. The unique pH glass formulation provides superior measurement stability and accuracy, and longer service life in high temperature applications up to 250 degrees F. (121 degrees C). The pH glass also increases response speed up to five times and allows longer duty cycles, compared to conventional sensors. The new reference electrode construction includes an ion barrier to protect and stabilize the reference potential in harsh conditions. Both electrodes are packaged in a rugged mechanical housing that facilitates installation, removal, cleaning, and calibration, reducing maintenance time and costs. The DolpHin line is available in flat and domed versions. The flat glass design promotes self-cleaning for longer service before operator intervention. The domed glass design operates longer and more accurately at high temperatures than conventional process pH sensors. The DolpHin Series sensors are designed for process industry applications that span the entire pH scale, have strong chemical concentrations and high solids, run at high temperature, and cycle from high to low temperature. These include: - Chemical and petrochemical manufacturing in reactors, scrubbers, etc. - Pulp and paper manufacturing in bleaching, thin stock, thick stock, and head box - Dairy processes for cheese processing and CIP (clean in place) - Electronics and metals processes involving etching, slurries, and metal finishing - Industrial and municipal waste water treatment, from incoming to final effluent
