Ph Measuring System Simplifies Installation
The Burkert 8201 pH measuring system's enamelled stainless steel finish provides nonstick performance for maximised hygiene while pH values are measured. The 'fit-and-forget' design of Burkert's 8201 pH measuring system enables the sensor to stay in process, even during CIP purification. This feature saves users both time and cost, by removing the requirement for sensor removal, cleaning and recalibration. The nonbreakable sensor also obviates the problems of fracturing with glass sensors.
Its enamelled stainless steel finish provides nonstick performance for maximised hygiene while pH values are measured. The hygienic design and robust, glass-free construction of the sensor mean that the unit is particularly suitable for use in high- end hygienic processes; for example, in the production of foods and active ingredients where the pH value of liquid mediums is measured. The 8201 provides long service life in these processes and high levels of accuracy with its ability to measure absolute pH values between pH 0 and pH 12, at medium temperatures up to 140C and process pressures up to 6bar.
The sensor is a highly integrated device, operating as a single-rod measuring cell, with the measuring electrode and reference electrode combined in one element. The sensor probe is a stainless steel tube, which also houses a Pt 1000 for temperature compensation. It is coated with an ion-sensitive enamel layer, providing an extremely smooth surface that prevents media from sticking during measurement, making the sensor very easy to clean.
During cleaning operations and CIP purification the sensor stays in the process. This saves time and money and means that expensive fittings can be dispensed with. Unlike many glass probes which have electrolytes that dry out in air, the 8201 sensor can be left dry for extended periods without any drying out or loss of performance.
The electrolyte itself is 3-molar KCI. This is stored in a separate electrolyte vessel and permanently connected to the electrode via a hose. The pressure of the electrolyte vessel is maintained slightly above process pressure by means of an attached pressure controller.
Burkert's 8285 modular process analysis system provides analysis of the measured values from the 8201 pH sensor. Designed to measure and process liquid analysis parameters, the 8285 is housed in a polished stainless steel enclosure, enabling its use in the field of biotechnology and the pharmaceutical and food processing industries. The 8285 sensor also suits the chemical industry, environmental engineering, water and waste-water treatment and power plants.
