2 Measuring Principle of PIOX R400

The refractive index n of a solution will be determined by means of transmitted light refractometry. A light beam propagates through the solution and will be refracted at the interface to a prism. The angle of refraction will be measured by a detector. The refractive index n of the solution can be calculated from Snell’s law of refraction:

refractive index of fluid



angle of incidence

 refractive index of prism

angle of refraction

Fig. 2.1: Path of light beam through the sensor

The light source is a special LED with a wave length  = 590 nm (sodium D-line) (see Fig. 2.1). The light passes an aperture, will be parallelized by a lens and reversed by a Dove prism. Then it enters the fluid through a window in the sensor head. When the light beam re-enters the sensor, it will be split at the vertex of a biprism and refracted at its inclined edges.

The two resulting measuring beams will be focussed by a lens projecting sharp images of the aperture on the detector, a CCD sensor with 2048 pixels.

The angle of refraction will be determined from the difference between the two measuring beam projections. The zero point will be calculated continuously, thus eliminating influences of process pressure and temperature.

2 Measuring Principle of PIOX R400

2.1 Determining the Concentration

The concentration can be calculated using the refractive index. In solutions, the refractive index varies with concentration and temperature (see Fig. 2.2).

If this relationship is known, one-to-one throughout the working area and external effects can be excluded, the measured refractive index and temperature can be used to determine the concentration according to the characteristics (see Fig. 2.2).

The characteristics can be determined at the FLEXIM laboratory or directly in the process. Characteristics for various sugar solutions have been measured in accordance with ICUMSA

and have been stored in the internal data-

base.

2.2 Temperature Compensation

The refractive index varies with temperature (see Fig. 2.2). In industrial applications, it is often not necessary to determine the refractive index at the actual process temperature. Instead, an equivalent value, measured at a reference temperature, is used. The measured refractive index will be converted by the transmitter accordingly.

The refractive index will be corrected automatically if temperature coefficients are stored for the medium. The reference temperature is used to calculate the temperature coefficients. This is an integral part of the set of coefficients for the medium.

ICUMSA (International Commission for Uniform Methods of Sugar Analysis)

Note!

If only the refractive index and temperature are measured, the concentration can only be determined for two-component liquid systems.

4 Handling

4.4 General Precautions

PIOX R400 is a precision measuring instrument and must be handled with care. To obtain good measurement results and not to damage the instrument, it is important to pay attention to the instructions given in this user manual, and particularly to the following points:

• protect the instrument from excessive shock

• manipulate the cables cautiously and avoid excessive cable bend

• connect the transmitter correctly to the power supply (voltage, frequency, connection to ground)

4.5 Service

Regular maintenance is normally not required. Always observe the handling precautions and the instructions given in this manual. If the instrument is installed correctly, in an appropriate location and as recommended, used cautiously and taken care of conscientiously, no troubles should appear.

4.6 Cleaning

Generally, the regular process cleaning and rinsing cycles are sufficient to keep the optical surfaces (prism and window) clean. However, depending on the liquid to be measured, it might be necessary to clean the measuring prism regularly to prevent the formation of deposits.

When cleaning with a caustic soda lye or any other aggressive chemical, first make sure that all parts in contact with the medium are resistant. If a manual cleaning of the prism or of the window is necessary, this can be made with a small pipe cleaner or with a soft cloth.

4.7 Calibration and Correction

Transmitter and sensor were calibrated by the factory. If the measured values need to be corrected, see section 8.2.

Attention!

Always observe the "Safety Instructions according to Directive 94/9/EC" (see document SIPIOX_R400).

Attention!

The degree of protection IP 65 of the transmitter is only guaranteed if the cables fit firmly and tightly in the cable glands, the cable glands are firmly tightened and the housing has been tightly screwed.

Attention!

Always handle the sensor carefully since it contains fragile optical components.

Note!

Only clean the prism with non-abrasive material!

UMPIOXR400V2-7-1EN, 2012-07-01 13

5 Selecting the Measuring Point

The sensor PIOX R400 is designed to be used directly in the process flow. It should be installed at a measuring point that is representative for the process and relevant to the given application.

If the measurement is integrated in a process control system, the sensor should be installed at a location where it can react quickly to process changes.

Fasten the sensor to a vertical pipe (rising pipe) that allows the fluid to flow upwards. The pipe is always completely full and the measurement prism is constantly surrounded by flowing fluid (see Fig. 5.1).

Fig. 5.1: Installation of the sensor with a welding adapter (full section view)

Attention!

Always observe the "Safety Instructions according to Directive 94/9/EC" (see document SIPIOX_R400).

Attention!

Make sure that the degree of protection of the transmitter, sensor and junction box is observed.

Attention!

If it is not possible to maintain the operational temperature transmitter, sensor and junction box have to be cooled.

Attention!

If the fluid temperature is > 100 °C and PIOX R400 is used in explosive atmosphere, the sensor must be shielded against heat radiation from the pipe. This ensures that the ambient, fluid and explosion protection temperatures remain within the specification of the sensor.

Attention!

Transmitter, sensor, junction box must not be thermally insulated (i.e., "not wrapped"). Otherwise, the permissible ambient temperature might be exceeded.

Page 14

14 UMPIOXR400V2-7-1EN, 2012-07-01

5 Selecting the Measuring Point

Install the sensor head so that the direction of flow is parallel to the prism edge (see Fig. 5.2).

Fig. 5.2: Orientation of measuring prism in pipe

To prevent deposits from forming on the measuring prism, ensure the following conditions:

• permanent minimum flow in the pipe

• the pipe diameter is relatively small at measurement point, i. e., the smaller the pipe diameter, the larger the pressure and the larger the self-cleaning effect

• the fluid temperature is relatively high but within the specifications of the sensor, i. e., if the temperature increases, the fluid solubility increases but the viscosity decreases

• the fluid pressure is relatively high but within the specification of the sensor, i. e., as the pressure increases, the fluid solubility increases and fewer gas bubbles form

If necessary, clean the measurement prism manually. Therefore, choose a measuring point where the flow can be interrupted and the sensor can be installed/removed without difficulty.

The selected measuring point should be easily accessible for service work.

Make sure that the transmitter is installed within the range of the cable. The ambient temperature at the installation site must be within the operating temperature range of the transmitter.

Note!

Protect the sensor against direct sunlight, rain and vibrations (pumps).

Note!

If the fluid is highly viscous, abrasive or contains solids in suspension, a bypass is recommended.

Attention!

Never wrap the cables (extension and sensor cables) around hot pipes.

8 Configuration

The measurement has now to be configured, i.e. the physical quantity, the unit of measurement and the offsets have to be defined. The configuration will be made separately for every available measuring channel. It can be modified at any time later by selecting the program branch PARAMETER again.

8.1 Selection of the Physical Quantity and of the Unit of Measurement

The following physical quantities can be measured with PIOX R400:

• refractive index

• normalized refractive index (a corrected refractive index based on a reference temperature)

• concentration in mass percent

• concentration in volume percent

• other customer specific physical quantities

The selected physical quantity is displayed by PIOX R400 during measurement. The normalized refractive index can be displayed simultaneously.

Note!

It is recommended to record the settings and measured values during the start-up of the PIOX R400 (see annex B "Start-Up and Maintenance Protocols").

In the main menu, select the program branch PARAMETER. Press ENTER.

Select the fluid to be measured in the scroll list. The scroll list contains glucose, saccharose, invert sugar, fructose, etc.

These fluids and their data sets are programmed in the internal database.

Three additional fluids each with two target values can be defined by means of the program RMKoeff and added to the scroll list (see chapter 13).

If a fluid is to be measured which is not in the fluid scroll list, select OTHER MEDIUM.

Note: Only Brix scales will be displayed as coefficients are not available for this fluid.

Press ENTER.

If data sets for two target values have been defined for a fluid, the parameters of the first target value (main physical quantity) will be requested first and then the parameters of the second target value (auxiliary physical quantity).

Note!

These displays is indicated only, if the menu item 1xMain+1xAUX has been selected in SPECIAL FUNCTION\SYSTEM SETTINGS\MEASURING\CONFIGURATION.

Note!

The correction of the refractive index takes place automatically if temperature coefficients are stored for the selected fluid.

8 Configuration

8.2 Input of Offsets

Corrections can be done as follows:

• input of offsets for the values calculated by the transmitter (e.g. concentration in mass percent)

• input of offsets for the measured primary physical quantities (e.g. refractive index, temperature)

8.2.1 Input of Offsets for the Values Calculated by the Transmitter

It is possible to correct the values calculated by the transmitter, i.e. by addition of a constant value to the selected physical quantity or the normalized refractive index. The corrections can be defined in the following displays:

The physical quantities and scales available for the selected fluid are displayed. Possible physical quantities are e.g. volume concentration or mass concentration. A typical scale is for example the Brix value for the concentration of a sugar solution.

Select the physical quantity. Press ENTER.

If several units of measurement are available for the selected physical quantity, they are now displayed.

The display will not be indicated if a scale is selected.

Select the unit of measurement to be used. Press ENTER.

If no offset is to be defined for the selected physical quantity or for the normalized refractive index, select NO. Otherwise select YES. Press ENTER.

The selected physical quantity is displayed in the upper line. Select YES to define an offset for this quantity. Press ENTER.

Enter the offset. The previously selected unit of measurement is displayed. The maximum possible offset is 10 % of the valid value range of the selected physical quantity.

Example: The glucose concentration is measured with the Brix scale selected as unit of measurement. The

Brix scale ranges from 0...100 °. The maximum offset is 10 °. Press ENTER.

If no offset for the normalized refractive index is to be defined, select NO. Otherwise select YES. Press ENTER.

Enter the offset for the normalized refractive index. The offset has to be within the range ± 0.100000. Press ENTER.

8 Configuration

8.2.2 Input of Offsets for the Measured Primary Physical Quantities

It is possible to correct the primary physical quantities (refractive index and temperature) measured by PIOX R400. These values will be corrected before they are used by the transmitter for the calculation of the selected physical quantities. The correction can be defined in the following displays:

8.3 Additional Input Values

If no supplementary values are needed for the measurement and if no auxiliary physical quantity needs to be defined, the configuration of the measurement is finished. Proceed with the configuration of the outputs (see chapter 9).

Supplementary input values are quantities that are measured by another instrument and transmitted to PIOX R400 via the inputs. Approximated values for these quantities have to be entered in the case that no input values are available during the measurement (e.g. failure of the corresponding instrument, defective cable).

Supplementary input values can only be taken into account when the corresponding coefficients for the selected fluid are available.

Supplementary input values of the fluid are: temperature, pressure, density, kinematic viscosity, dynamic viscosity, conductibility, pH value, sound velocity, volume flow.

The inputs are described in chapter 14.

If the sensor values are not to be corrected, select NO, press ENTER and continue with section 8.3. Otherwise select YES. Press ENTER.

Select YES if a correction for the measured refractive index is to be defined. Press ENTER.

The offset has to be within the range ± 0.0500. Enter the offset. Press ENTER.

Select YES if an offset has to defined for the measured temperature. Press ENTER.

The offset has to be within the range ± 10.00 °C. Enter the offset. Press ENTER.

11 Output Options

If analog outputs or the serial output are configured, they have to be activated in program branch OUTPUT OPTIONS. The status outputs also will be configured in this program branch

In the program branch OUTPUT OPTIONS:

• the damping factor of the measured values will be defined

• the installed inputs and outputs will be activated

• alarms will be defined and activated

• the serial output of the measured values will be activated

11.1 Damping Factor

Each displayed measured value is the floating average of all measured values of the last x seconds, where x is the damping factor.

A damping factor of 1 s means that the measured values are not averaged as the measuring rate is approx. 1/s. The default value is 10 s. This is appropriate for normal measuring conditions.

Strongly fluctuating readings caused by high dynamics require a larger damping factor.

11.2 Activation of the Serial Output

11.3 Activation of the Outputs

The activation displays of all the configured outputs will now be displayed one after another. The configuration of the outputs is described in chapter 9.

Three values relating the measured values to the output values (current, voltage, frequency) have to be entered.

Select the program branch OUTPUT OPTIONS. Press ENTER.

Select the channel for which the output options are to be set.

This display will not be indicated if the transmitter has only one measuring channel.

Enter the damping factor. Values between 1 s and 100 s will be accepted. Press ENTER.

If the serial output has been configured in program branch SPECIAL FUNCTION, SERIAL OUTPUT will be displayed now. The installation of the serial output is described in chapter 10.

Select YES to activate the output of the measured values to the serial interface, NO to deactivate it. Press ENTER.

Select YES to activate the specified output,

NO to deactivate it. Press

11 Output Options

In the menu item MEAS.VALUES will be requested whether the sign should be considered for the output of the measured values.

The LOW-SCALE VALUE and FULL-SCALE VALUE determine the range of measured values which will be mapped on the physical range of the output. For all values greater than the FULL-SCALE VALUE, the output value will be clipped to the maximum output value (OUTPUT MAX). For all values smaller than the LOW-SCALE VALUE, the minimal value (OUTPUT MIN) will be output. The LOW-SCALE VALUE and FULL-SCALE VALUE can be negative or positive. The range of measured values does not need to be symmetrical. In most of the cases, the LOW-SCALE VALUE will be the lowest measured value expected, the FULL-SCALE VALUE the highest value expected.

After the program branch OUTPUT OPTIONS is completed, the main menu will be displayed again. Start the measurement as described in chapter 12.

11.4 Status Output (Alarms)

Each measuring channel of PIOX R400 has 4 status bits (R1...R4) which can used to define a status output (alarm output). First activate the status bits and then configure the status output.

In the following displays, only the status bits which have been linked to an output or to the serial output will be shown. If the needed status bit is not displayed, it has to be linked to an output (see chapter 9).

11.4.1 Selection of the Status Bit

If no status output is to be defined or no settings are to be modified, select SKIP SETUP in the scroll list STATUS OUTPUT. The program branch OUTPUT OPTIONS will be finished. Start the measurement as described in chapter

12.

All status outputs can be switched off at once by selecting the list item DISABLE ALL. The program branch OUT- PUT OPTIONS will be finished. Start the measurement as described in chapter 12.

11.4.2 Activation of the Status Bit

Select SIGN if the sign of the measured values should be considered for the output, ABSOLUT if it should not be considered.

Enter as LOW-SCALE VALUE the lowest measured value expected. The displayed unit of measurement is the unit of the source item of the output. The LOW-SCALE VALUE is the measured value corresponding to the lower limit of the physical range of the output.

Enter as FULL-SCALE VALUE the highest measured value expected. The FULL-SCALE VALUE is the measured value corresponding to the upper limit of the physical range of the output.

Select the status bit to be used for a status output. The designation of the status bit is followed by the output to which it is linked.

Select YES to activate the selected status bit. Select NO to deactivate the status bit and return to the previous menu item. Press ENTER.

11.4.4 Definition of the Triggering Condition

When the source item is selected, the triggering condition of the status output can be defined, i.e. the condition that has to be fulfilled to trigger the output. Three alarm functions are available. They are listed in Tab. 11.2.

The hysteresis is a symmetrical range around the limit in which fluctuation is permitted. The output will be triggered when the measuring value reach the upper limit of this range and when the measuring value fall below the lower limit.

11.4.5 Setting of the Triggering Period

It is possible to trigger the status output as soon as the defined condition is met. It is also possible to trigger the output only when the condition has been met without interruption for a certain predefined period of time.

If the source item type SENSOR VALUES is selected, select the source item in the scroll list. Press ENTER.

Tab. 11.2: Alarm functions

alarm function description

MAXIMUM (x>trig)

The status output will trigger when the source item exceeds a certain maximum value.

MINIMUM (x<trig)

The status output will trigger when the source item falls below a certain minimum value.

SOURCE ERROR

The status output will trigger when the source item is not valid.

Example: In the example given above, the function needed can be reached by selecting the alarm type MAXI-

MUM (x>trig) for the status output. HIGH LIMIT of the output should be set to 30 °.

Select the alarm function. Press ENTER.

If HIGH LIMIT or LOW LIMIT is selected as alarm function, enter now the maximum or minimum value for the source item. Note that the signs of the source item and of the limit will be considered. Press ENTER.

It is now possible to define an hysteresis for the status output. This function is useful to avoid a constant triggering of the output by measured values fluctuating around the limit.

Example: If a variation of 0.5 °Brix about the upper limit is allowed, set the hysteresis to 0.5 °Brix for the 30

°Brix limit. The alarm will trigger at 30.5 °Brix and at 29.5 °Brix. Small fluctuations around 30° Brix do not have any effect on the alarm.

Select

YES to activate the alarm immediately. Select NO to activate

the alarm only after the switching condition has been met for a certain period of time. Press ENTER.

• NO DETECTION: The external transducer does not evaluate the signal before sending it to the transmitter.

• If I1 < MIN (4.0 mA): An error is sent if the value falls below the previously defined measuring range.

• If I1 > MAX (20.0 mA): An error is sent if the value exceeds the previously defined measuring range.

Note!

The error behavior of the external transducer is described in the specification.

If I1 < MIN (4.0 mA) is selected:

Enter the lowest value for the measuring range before an error message is sent.

This value is given in the specification of the external transducer.

If I1 > MIN (20.0 mA) is selected:

Enter the highest value for the measuring range before an error message is sent.
