General Purpose ph/orp Sensors Product Data Sheet LIQ_PDS_3900 / Rev. F December 2014 General Purpose ph/orp Sensors SMART preamplifier-stores calibration and other data. Extended sensor life provided by double junction reference. Enhanced performance and increased life with minimized glass cracking provided by field-proven AccuGlass ph glass formulations. VP8 quick cable-to-sensor release, provided by the watertight VP8 multiple-pin connector, eliminates cable twisting. Maximum chemical resistance provided by rugged polyphenylene sulfide body, completely sealed to eliminate sensor leakage. NEW 3/4 and 1 mounting solutions to meet a variety of application installation requirements. Optimum versatility with various mounting options provided by one-piece construction with process threads in two places. Operates in sub-zero temperatures down to -10 C (14 F). Responds to changes in ph at a minimum conductivity of 0.1mS/cm when used with the low flow cell panel. 3900 Insertion/Submersion Sensor Features and Applications General purpose ph/orp 3900/3900VP sensor. The double junction reference aids in the sensor s resistance to harsh environments and helps prolong sensor life. The 3900 and 3900VP are provided with a double junction reference, which protects the reference element from poisoning ions such as ammonia, chlorine, cyanides, and sulfides in the process. Both models are made with porous Teflon junction positioned near the ph/ ORP-sensitive membrane. The SMART preamplifier option becomes enabled when used with the 56, 1056, 1057 analyzers and on the 6081P wireless transmitter. The ph-loop capabilities include auto-recognition of the SMART sensor, automatic upload of calibration data and associated time stamp, historical recording of ph diagnostics (slope, offset, reference impedance, glass impedance). This trending data allows technicians to predict frequency of maintenance and estimate sensor life for a particular process condition. Additional SMART features include factory calibration, resetting SMART sensor calibration data, user menus, and manufacturing information. The AccuGlass ph glass formulations exceed industry standards. The AccuGlass ph glass is a result of many years of glass research resulting in a formulation which has been found to increase the life of the sensor. Unlike other ph glasses presently on the market, this glass resists cracking especially at higher temperatures and reduces sodium ion error commonly found in high ph applications. Overall, the AccuGlass formulation enhances the sensor performance to measure ph more accurately and have a longer sensor life than ever before.
General Purpose ph/orp Sensors December 2014 Features and Applications (cont.) The 3900VP is offered with a watertight sensor-to-cable connector which eliminates re-wiring and cable twisting when replacing sensors. The Variopol VP multiple pin connector is an integral part of each sensor model and uses a mating VP cable. Once the cable is installed and wired to the analyzer, sensors are easily replaced without replacing the cable and without rewiring the analyzer. Also the cable can be disconnected from the sensor before removal from the process which eliminates cable twisting. The 3900 and 3900VP are housed in a molded PPS body, making each sensor virtually indestructible and chemically resistant. Complete encapsulation eliminates leakage or high humidity problems traditionally found in other ph/orp designs. The simplified construction, designed with user convenience in mind does not require electrolyte (KCl) replenishment or any high maintenance troubleshooting procedures. Installation is easily achieved through the wide variety of mounting configurations. Both models feature 1 and ¾ inch (MNPT) front facing connections for insertion, submersion, or flow-through ph and ORP applications. Both models are combination sensors (ph, reference, and temperature within sensor body) and measure ph or ORP (Oxidation/Reduction Potential) of aqueous solutions in pipelines, open tanks, or ponds. The 3900 and 3900VP are suitable for virtually all applications and are compatible with Rosemount Analytical and other manufacturers instruments.
