General information

2.2 Product overview

DANGER

This product is not suitable for use in potentially explosive atmospheres.

WARNING

The UV rays from the flash bulb are harmful to eyes and skin. Do not look directly through the
measurement window during operation under any circumstances. Remove the measurement
sensor from operation before carrying out any maintenance or installation work.

The FP 360 sc sensor is a UV fluorimeter used to continuously measure the concentration
of PAH (polycyclic aromatic hydrocarbons) in water. The measurement values can be
converted to reflect the total oil content for mineral oils using lab data.

The sensor may need to be installed with additional accessories depending on its area of
application.

Area of application Installation with Sensor variants

Open channels, shafts, tanks (solid
matter max. 200 mg/L)

Measurement media without solid
matter with continuous, low sample
throughput

Do not apply the sensor to any hard mechanical effects.

2.3 Measuring principle

The measuring principle is based on the fluorescent properties of PAHs. After excitation
caused by UV rays, PAHs emit light with longer wavelengths after a short time delay. The
intensity of this light is measured. This measuring principle is considerably more sensitive
than absorption and scattered light measurement. It is possible to detect even the slightest
trace of PAH contamination in water. PAHs are integral parts of most mineral oil products
and are a very specific indicator of oil contamination in water bodies and process water.

2.4 Product components

Each sensor is supplied with

• a connector cable with safety sleeve,

• a shackle,

• a basic user manual and

Chain mount kit Sensor with or without cleaning unit

4.5 Calibration

4.5.1 Factory calibration

The calibration curve zero point and slope are preset. Retrospective calibration of these
basic settings is generally not required outside of the inspection intervals.

Do regular zero point checks to make sure that impurities or faults are being detected
(refer to section 4.5.3 on page 21).

If the zero signal increases due to the measuring medium components or the installation
conditions, you can compensate for this influence via an offset correction. Carry out a lab
analysis of the sample to do this. If there is no PAH/oil contamination in the measuring
medium, enter the measurement value shown by the device as the offset (refer to section

4.5.4.2 on page 22).

4.5.2 Process calibration/adjustment

The sensor is pre-calibrated with various concentrations of a special calibration standard
in ultra-pure water. These ideal measurement conditions rarely occur in reality. The
measurement values shown are qualitative trend indicators if no adjustment is made to the
on-site measurement conditions.

If you require quantitatively correct measurement values, either a slope adjustment or a
multi-point calibration needs to be carried out. Both of these operations must be carried
out on site using lab analysis data. Basic prerequisites for quantitative measurements are
precise knowledge about the oil type in occurrence and constant measurement conditions,
e.g. in cool water in a heat exchanger. If several oils are present in varying quantities, it is
generally not possible to carry out a quantitative measurement.

If the measurement conditions change, you must check the accuracy of the results again
through lab analyses and make any adjustments where necessary.

The measurement conditions can change in terms of

• Composition of PAH or oil impurities

• Distribution of impurities in water

• Tem p

• Measuring medium composition

• Measurement sensor and measurement window

4.5.2.1 Determination of factors and adjustment of slope

To adjust the slope:

1. At the sensor installation site, draw a lab sample of the measuring medium and
promptly analyze the sample for PAH and oil content.

2. Make a note of the measurement value shown on the controller at the time of the
sample being taken. Make sure the correct unit is shown for the measurement value,
e.g. as ppm oil.

3. Repeat steps 1 and 2 several times.

4. Use the sample value and the value shown on the controller at the time of sampling

to calculate a factor.

20

5. Find an average value from the factors.

6. Enter the factor as the slope (refer to section 4.5.4.1 on page 21).

Example for engine oil Example for naphthalene

Lab value: 4.0 ppm oil
Measurement value shown
Calculated factor: 1.67

1

At the time of sampling

1

: 2.4 ppm oil

Lab value: 420 ppb PAH
Measurement value shown1: 120 ppb PAH
Calculated factor: 3.5

It is advisable to adjust the slope if the following conditions apply:

Operation

• If th

• Th

e measuring sample is PAH-/oil free, the measurement value must almost be zero.

e factors calculated from the lab values must enable a sensible average value to be

derived.

If these conditions do not apply, do a multi-point calibration.

Note: If both the zero point and the slope must be changed, use a 2-point calibration (refer to
section 4.5.4.3 on page 22).

4.5.2.2 Multi-point calibration

In the event of a multi-point calibration, enter the lab value as the target value and the
value shown as the actual value. Make sure that all values are entered in the same unit,
e.g. oil in ppm. (refer to section 4.5.4.3 on page 22).

4.5.3 Check the zero point

• Medium: ultra-pure water

• T

arget value: < 1 ppb. Clean the window in the event of deviations.

Use a glass container (not plastic) large enough to enable the measurement to be taken
with an 8 to 10
1000 mL glass beaker). Place a black, non-reflective underlay under the container and
switch off artificial lights during the measurement process.

Note: In air, the measurement value displayed is not exactly zero due to reflections on the window
surface. This is standard sensor behavior and not an indicator of malfunction.

Section 5 Maintenance

The inside of the sensor is maintenance-free.

The cleanliness of the measurement window in the sensor head has an impact on the
accuracy of measurements. Check the measurement window at regular intervals to make
sure it is clean. The required frequency of these checks is dependent on the measuring
medium. Also do a check in the event of unusually high measurement values and clean
the measurement window if necessary (refer to section 5.3 on page 24).

For sensors with a cleaning unit, adjust the frequency of cleaning to the measurement
conditions. The inspection interval must be shortened to reflect any increase in solid
matter.

Individual components of the suspension device (shackle and chain of the chain mount kit) are
made of stainless steel and may corrode.

5.2 Maintenance for the connectors on the sensor

The 8-pin connector on the sensor is designed for constant usage under water. The
connector is lubricated with high-performance grease at the factory and does not require
any additional maintenance from the recommended sensor inspection cycles.

To maintain the performance of the connectors:

• Protect the neoprene components of the connector against high temperatures and
intense solar radiation. If this cannot be avoided, moisten the dried out neoprene
components with clean, clear water. Subsequently, loosen the connector.

• The pins must always be lightly lubricated. Only apply a very thin film of lubricant.
Recommended lubricants are Loctite
The lubricant must not come into contact with the measurement window.

Section 9 Warranty and Liability

The manufacturer warrants that the product supplied is free of material and manufacturing
defects and undertakes the obligation to repair or replace any defective parts at zero cost.

The warranty runs for 24 months. If a maintenance contract is taken out within 6 months of
purchase, the warranty period is extended to 60 months.

With the exclusion of the further claims, the supplier is liable for defects including the lack
of assured properties as follows: all those parts that, within the warranty period calculated
from the day of the transfer of risk, can be demonstrated to have become unusable or that
can only be used with significant limitations due to a situation present prior to the transfer
of risk, in particular due to incorrect design, poor materials or inadequate finish will be
improved or replaced, at the supplier's discretion. The identification of such defects must
be reported to the supplier in writing without delay, but no later than 7 days after the
identification of the fault. If the customer fails to notify the supplier, the product is
considered approved despite the defect. Further liability for any direct or indirect damages
is not accepted.

If instrument-specific maintenance and servicing work defined by the supplier is to be
performed within the warranty period by the customer (maintenance) or by the supplier
(servicing) and these requirements are not met, claims for damages due to the failure to
comply with the requirements are rendered void.

Any further claims, in particular claims for consequential damages cannot be made.

Consumables and damage caused by improper handling, poor installation or incorrect use
are excluded from this clause.

The process instruments of the manufacturer are of proven reliability in many applications
and are therefore often used in automatic control loops to provide the most economical
possible operation of the related process.

To avoid or limit consequential damage, it is therefore recommended to design the control
loop such that a malfunction in an instrument results in an automatic change over to the
backup control system. This establishes the most secure operating condition for the
environment and for the process.
