14. Introduction 1 Introduction 1 1 Overview The 4909 Conductivity Cell Insertion Removal Assembly is designed for use in a pipeline or closed vessel where it is desirable to remove the cell for inspection and maintenance without shutting down the system and releasing the pressure The assembly comprises a 4908 Conductivity Cell and a 31074357 Removal Device which are shown assembled in Figs 1 2 and 1 3 It is to be used in applications for which maximum pressure does not exceed 125 psig and can be reduced to 50 psig during insertion and removal of the cell Maximum operating temperature is determined by the temperature compensator range Do not use in solutions above 80 C The depth of insertion is given in Figs 3 1 and 3 2 The conductivity cell is made of polyethersuflone PES which is resistant to most corrosive inorganic chemicals over a wide range of temperatures common exceptions are chlorinated hydrocarbons and ketones Sample solutions come into contact with the PES and the platinum or nickel electrode surface of the cell Any cell constant can be supplied with either electrode material The only materials of the 4909 Assembly with which the sample solution may come into contact are in the removal device which is comprised of CPVC plastic Teflon EPDM and Viton materials The automatic temperature compensator may be built into the cell as shown in Section 2 2 Model Selection Guide CAUTION Specific parameters of your process
