Barben Analytical Model 547 pH/ORP Sensor

AxialIon Path® Reference · Patented designincreases sensor life, accuracy and reliability · High resistance topoison: Reduced calibration offset error · Large surface areareference junction eliminates plugging issues · Eliminates error dueto fluctuating pressure · No exotic gel orpolymer electrolyte which may be incompatible with the process The Model 547 is a replaceable, cartridge stylesensor. It is designed to fit into a variety of sensor holders for directinsertion into the process. When used with a metallic sheath the 547 sensor canprovide variable insertion depth for hot tap ball valve installations as wellas the ability to withstand pressures up to 2500 PSIG with Barben™s highpressure housing assembly. Insertion Depth The depth that pH / ORP sensor protrudes into the pipelinecan greatly affect the measurement. Applications where the sensor tip isrecessed can lead to coating and slow response. In high particulateapplicati ons abrasion of the electrode can be a concern. A typical installation goal is to get the sensor tip at least1/4" (6mm) into the stream. At this depth coating issues lessen andresponse improves due to flow velocity.
