5 1. About the device 1.1. Introduction The series 3200 Dual Channel Conductivity TCU is based on the 4-electrode conductivity principle. Using an advanced compensation technology, the 3200 TCU meets the demands of conductivity measurement in a wide range, from low conductivities in ultrapure water in the low conductivity end to acids and bases in the high conductivity end. The TCU is housed in a painted aluminum case and can be either panel-mounted or wall-mounted. Its front panel incorporates an LCD display and an operating keypad. It is operated by using the keypad and a menubased concept. The set-up is stored in a non-volatile memory that preserves the settings even during power failures. The settings can be protected with a password if necessary. In the 4-electrode conductivity principle, current and voltage are measured using separate pairs of electrodes. The advantage of this principle is complete independence of electrode over-voltages, which makes it possible to use small electrodes. Small electrodes are good at both high and low conductivities: at high conductivities they are robust against errors caused by the polarization effect, and at low conductivities they help avoid errors due to electrode capacitance. One or two sensors can be used. With two sensors the TCU can be programmed for differential conductivity or conductivity ratio. Any one of the two channels can be calibrated from the keyboard. Any one of the two sensors can be used with automatic cell constant (read from stored factory calibration) or with manually entered cell constant. The TCU contains two galvanically isolated, individually programmable current outputs. Any conductivity or temperature can be directed to an output. The outputs can be programmed for linear, bilinear, logarithmic, compressed or expanded conductivity output, or for linear temperature output. Two individually programmable alarms with relay contact outputs are available. The alarms can be programmed for conductivity, temperature, or USP 645 alarm as maximum or minimum alarms, with or without time delay. In case of an error the Error Detection system will show a message on the display. Features of the TCU: Individual calibration of channels Individually selectable conductivity unit and reference temperature for channels Selectable cell constant (manual or automatic) for sensors Selectable temperature unit Configurable error detection and alarm system Dual Conductivity TCU series Installation & operating manual K14278 V1.5 EN

6 1.2. Conductivity sensors The conductivity sensors use the 4-electrode principle that compensates for the over-voltage of the current electrodes, caused by scaling and precipitation. Errors from cable stray capacitance and leakage are compensated for by means of compensation wires in the sensor cable. The sensors are equipped with a union nut for mounting. The screened sensor cable is attached to the sensor. The sensor is connected to the TCU by a snap fit strip connector. Extension cables up to max. 50 meters are available. The extension cable is equipped with strip connectors or plugs in both ends. Temperature is measured by a platinum resistance thermometer, the cell constant is measured from a resistor. Both of these are located in the sensor and connected with a 4-wire connection. Temperature compensation is performed in software, and a versatile program of temperature compensation algorithms is available. More detailed information on each of the 4600 and 4700 series sensors used with the Dual Channel TCU 3200 can be found in the Data Sheets, at the end of this manual Temperature compensation Conductivity calculation is based on the "raw" conductivity TCU, the actual (= measured) temperature, and the selected reference temperature. Conductivity result is then calculated according to the selected temperature compensation. Ultrapure water water with conductivity of 5 10 µs/cm or lower at 25 C requires special attention. In this conductivity range, the conductivity of the water itself (arising from autoprotolysis) cannot be neglected, as it adds to the conductivity of all other ions present in the electrolyte. The temperature dependences of the different ions combine in such a way as to invalidate any standard temperature compensation. Several substances must be considered: neutral salts, strong or weak acid, strong or weak base, etc. Only neutral salts have no effect on the autoprotolysis of water, and therefore the temperature compensation must be selected to fit the actual application Cable compensation At low conductivities the effect of cable stray capacitance and leakage becomes significant. Depending on cable length, the actual conductivity and the measuring frequency, an additional amount of conductivity will be added to the reading. The built-in cable compensator measures the error signal and compensates for it. Thus the reading is independent of cable length at any conductivity down to µs/cm, including the ultrapure water level. The orthogonal-symmetrical cable, used with series 4600 and 4700 sensors, also compensates for the magnetic coupling between the wires to the current or voltage electrodes, thereby achieving an accurate result even at very high conductivities and with long cables.

7 2. Installation 2.1. Installation notes Important issues when planning TCU installation: Whether mounted on a wall, in a panel or onto a piping or cable tray, the place should be free of vibrations and mechanically shocks should not occur. Make sure that there is no potential difference between sensor and TCU! If TCU is mounted on a cable tray, the cable tree should be electrically connected to the process piping. Make sure there is no potential difference between the protective ground and the process piping and/or TCU mounting site. Look out for ground loop currents that can cause a fluctuating or faulty reading. Protect the instrument from downpour. If necessary use a Protection Shield. Protect the instrument from excessively high or low temperatures and from direct sunlight. Minimize the length of sensor cable as much as possible. Protect the sensor cable from mechanical impact and excessive high or low temperatures Dimensions Ø5.2 esc 144 OK Important issues when planning sensor installation: Choose the sensor mounting location so that there are no air bubbles or pockets. Air will lower the reading and cause an unstable signal! Pay attention to pipe diameter when choosing the installation site for sensors with external electrodes (see Fig. 13). If the pipe diameter is too small, the electrodes will take interference from the pipe walls. Mount the sensor at a place where it is protected from mechanical impact and can be accessed and extracted from the process for service. Always install the sensor so that the temperature sensor or sensor opening faces the incoming liquid flow Fig. 1. Installation dimensions, in millimeters.

13 2.7. Mounting the sensor The sensor should be mounted at a place where there will be no occurrence of air pockets or bubbles. Air will lower the reading and cause an unstable signal. See Fig. 14 for information on the different installation locations. Make sure to install the sensor in the correct position relative to the flow. An arrow label (Fig. 12) indicates the position of the sensor: external electrode: Pt 1000 facing the incoming flow internal electrodes: sensor opening facing the incoming flow Example: if the sensor is mounted in a pipe section with upward flow, make sure that the Pt 1000 / sensor opening is on the underside. Also pay attention to pipe diameter when choosing the installation site for sensors with external electrodes. If the pipe diameter is too small, the electrodes will take interference from the pipe walls. Fig. 12. The arrow indicates on which side of the sensor the electrodes are. Fig. 13. Sensors with external (A) and internal (B) electrodes. Dual Conductivity TCU series Installation & operating manual K14278 V1.5 EN

14 Preferred mounting: A: Directly in an upstream pipe. B: Directly in an elbow between a horizontal and an upstream pipe. Horizontal mounting is recommended, with sensor pointing towards incoming flow. C: Using a measuring chamber connected across a pump. Alternative mounting: D: Using a measuring chamber connected between two different places of an upstream pipe. In this case it may be necessary to install a throttle plate in order to gain enough flow through the measuring chamber. E: This installation will prevent the signal from going to zero in case the pipe runs empty. It may minimize the appearance of air bubbles around the sensor. F, G: Installation in a downstream pipe is generally not recommended if the pipe can run empty. If the sensor must be installed in a downstream pipe it may help to keep the pipe filled by installing a throttle plate just after the measuring point. Unsuitable locations: H, I, K: Avoid these installations! Mounting of measuring chamber: Mount the measuring chamber in a vertical position, with an upward flow direction. Use short connecting pipes. Insulate piping and measuring chamber to minimize heat loss. If connecting over a pump, make sure the pump has enough capacity. Shut-off valves are recommended so that the sensor can be removed for service without shutting down the process. When using valves to control the flow through the measuring chamber, keep the inlet valve fully open and throttle the flow with the outlet valve. I A C K B H G F E D Fig. 14.

Low / High limit: Set the values corresponding to the 4 ma and 20 ma current signal for the selected variable. For UPW set-up conductivity in µs, for standard set-up in ms. If set Off, the high limit sets a fixed output current, with 0 as 4 ma and 100 as 20 ma. In this case the low limit is not used. PV 0-x- compresses the output current. Low limit is not used. If the measured temperature is sent to an ma output, note that the output range is not automatically reprogrammed if the temperature unit is changed (under "System"). For example, if the low and high limit are set to the range C, changing the temperature unit to F gives an output range of F which corresponds to C. Table 1.
