    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.
  • Page 8 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).

    40 tee is required. The basic cell can be converted to a flow cell for either bypass or in-line arrangements by use of the PES flow-cell housing (Honeywell Part 276127) shown in Figure 3-2. However, the temperature and pressure specifications listed for this flow chamber under Specifications apply.
  • Page 12: Flow-Type Mounting

    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.

    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.

  • Page 21: Maintenance

    Maintenance 5. Maintenance 5.1 Introduction If abnormal readings occur, this may indicate poor response because the cell is not filled with process solution. Check the cell installation. Note that a grayish dull surface on the cell plastic (normally glassy) can result from exposure to temperatures above 140°C. The only maintenance which may be required is occasional cleaning in certain applications.
  • Page 22: Platinizing The Cell Electrodes

    Maintenance 5.4 Platinizing the Cell Electrodes Only the electrodes having constants 10 and 50 must be replatinized if the velvety-black deposit has been rubbed off the electrodes in service or in cleaning or if platinized electrodes are recommended and this black deposit is not present when the new cell is received.
