2 Safety
2.1 Proper use
The sensor is used to analyze substances and samples in production and in the labo-
ratory. The sensor is intended exclusively for that purpose.
The sensor can be used in laboratories and production facilities for the following oper-
ations:
Quality control
Process optimization
Reference measurements
2.2 Use other than that intended
Use of any other kind than that described in the section Chapter2.1 "Proper use",
page7 and any application that does not comply with the technical specifications
(see Chapter3.6 "Technical data", page15) constitutes use other than that in-
tended.
In particular, the following applications are not permissible:
Using the sensor in areas for which the sensors are not certified. For certification
details see Chapter3.4 "ATEX rating", page14
Use of the sensor in a potentially explosive atmosphere without an overall assess-
ment by the responsibility holder.
Use of a sensor of which the screw sealing cap is damaged.
Damage or hazards attributable to use of the product other than as intended are en-
tirely at the risk of the operator alone.
2.3 Location of safety notices and warning signs on the product
The following safety signs and warning symbols are present on the sensor.

2.4 Safety features
2.4.1 Thermostat
A thermostat in the device switches off the internal power supply if the temperature
exceeds 60 °C +/- 5 °C.
2.5 Residual risks
The device has been developed and manufactured using the latest technological ad-
vances. Nevertheless, risks to persons, property or the environment can arise if the
device is used incorrectly.
Appropriate warnings in this manual serve to alert the user to these residual dangers.
2.5.1 Risk of explosion from opening up the sensor
Opening up the sensor in potentially explosive atmospheres can cause an explosion.
uDo not open up the sensor housing.
2.5.2 Risk of explosion from unplugging the device power plug

3 Product description
3.1 Description of function
The sensor is an optical instrument for nondestructive determination of substances
and concentrations in a sample.
A sample absorbs and reflects light across the entire wavelength spectrum according
to its color and chemical composition. The signal reflected by the sample is recorded
and analyzed by a spectrometer.
The sensor uses a lamp to produce near-infrared radiation that interacts with the
molecules of the sample. The interaction between sample and light produces a
characteristic spectrum.
The light reflected from the sample is collected through two sets of fiber optics that
direct the light to the NIR and visible spectrophotometers, respectively. The visible
spectrophotometer consists of a diffraction grating to spatially disperse the light ac-
cording to wavelength and a silicon photodiode array containing multiple elements
which measure the light intensity for specific wavelength intervals. The NIR spec-
trophtometer consists of a diffraction grating to spatially disperse the light accord-
ing to wavelength and an indium-gallium-arsenide photodiode array containing
multiple elements.
The measurement results produced are converted to data sequences.
The data sequences are transferred to a computer via an interface.
A computer program compares the data sequence curve with a calibration model
and in that way determines the chemical composition of the sample.
