Fluorescence spectral data
There is no universal fluorescence spectrum for all oils. Rather, the spectrum depends on the composition of the oil. Refined oils consist mainly of aromatic hydrocarbons, which in solution in water are often indicated in the BTEX collection parameter. The graph shows examples for typical fluorescence spectra of some refined oils. The BlueTrace oil in water sensor is suitable for the measurement of refined oils, BTEX and aromatic hydrocarbons.

Oil particles
When light of a certain wavelength hits an oil particle, the oil emits light of a different wavelength shortly after excitation. This effect is called fluorescence. Fluo-rescence occurs not only in oils, but also in other substances. The BlueTrace oil in water sensor uses this effect to determine the concentration of refined oils in water.A transmitter installed in the sensor emits light at around 280 nm. The oil particles in the water absorb this energy and then emit light in a range from 300 to 400 nm. This light is measured by a detector.
The Jablonski diagram shows the fluorescence effect in detail. The oil particle absorbs the energy of the light, changes to a higher, unstable energy level and then falls back to the lower energy level. Part of the energy is released by the fluorescence effect. The intensity of the fluorescence is directly dependent on the concentration. By measuring the intensity at the detector, the concentration of the oil in the water can be determined.

Specific calibration to specific oil typesSince the fluorescence spectrum is extremely depend-ent on the refined oil, the sensor functions optimally with a specific calibration to this oil. Also, the absorp-tion of the water has an influence on the measure-ment, so that for the calibration the oil should be mixed in the water, which is to be expected locally. In low concentrations a linear behaviour can be expect-ed, therefore, a two-point calibration can be sufficient. However, at least a three-point calibration is recom-mended.
Easy calibrationThe BlueTrace can easily be optimally calibrated to the specific application. All you have to do is hold the sensor in the prepared samples and then perform a multi-point calibration. For this purpose, only the reference values have to be entered into the BlueBox controller or the corresponding software.

Functions & Features
Selectable Measuring Range
The sensitivity of the receiver can easily be changed either directly on the controllers of GO Systemelek-tronik, or with the help of the freely available PC program. Thus, the sensor can optimally be adjusted to the required measuring range.
Modbus Interface
The BlueTrace features a Modbus RTU interface. This means that the sensor can not only be connected to a GO Systemelektronik controller, but can also be inte-grated into third-party controllers or directly to a PLC. The necessary Modbus protocol is freely available. Settings or calibrations are stored directly on the sensor and can be adapted with the freely available PC program. The sensor only needs to be connected to a PC, for example with a Modbus USB converter.
Robust Design
The BlueTrace is available in stainless-steel and titani-um. For most applications, stainless steel is sufficient. However, if the sensor is used in corrosive media or harsh environmental conditions, it is recommended to use the BlueTrace in a titanium housing.
