Introduction 1. Introduction 1.1 Overview These cells form the sensing network for industrial analyzers and transmitters designed to make continuous measurements of electrolytic conductivity. The cells are primarily suited to measurements in effluents of ion-exchangers and distillation columns; but appropriate constants are provided for many other applications, including measurements in micro-electronic component washing and plating-rinse effluents. Universal in mounting, any of the cel

Introduction The cell constant is selected according to the range of the measuring instrument used and the solution measured. In general, a high-constant cell is used for solutions having low electrical resistance (high conductivity) and a low-constant cell is used for solutions having high electrical resistance (low conductivity). Automatic Temperature Compensation (ATC) during the measurement is provided by a built-in temperature sensing network located near the cross-channel or guard-t

Installation 3. Installation 3.1 Overview The conductivity cell is secured permanently to the 1” N.P.T. bushing which is used for all types of mountings. Although the physical appearance of the various cells is the same (except for length), the cell construction differs according to the constant. On the 10 and 50 constant cells, the electrodes are short tubes located midway inside the two parallel tubular channels that run lengthwise through the cell, and are open to the sample at both

Installation 3.4 Flow-Type Mounting The cross-channel or guard-tube hole in the cell must always be covered by the solution and the solution level must be 1-1/2 inches above these holes. When mounting the cell in a pipe tee such as shown in Figure 3-1, have the solution enter the tee from below and exit to the side. As shown, the guard-tube hole is in line with the horizontal pipe run. However, if it is possible that the pipe line will not be full at all times, locate the hole just belo

C C CE E EL L LL L L IN IN IN Installation 3.6 Insertion-Type Mounting The cell can be inserted into a 1” N.P.T. threaded opening, but it is imperative that the tank or chamber be full under all process conditions. Make certain the liquid head is above the cell location. A vertical insertion (from above) or a horizontal insertion can be used. To install, simply tighten the cell into a 1” N.P.T. threaded opening (using a Teflon thread compound such as Teflon tape) so that the entire elect
