2 Safety
2.1 Proper use
The sensor is used to analyze substances and samples in production and in the
laboratory. The sensor is intended exclusively for that purpose.
The sensor can be used in laboratories and production facilities for the following
operations:
Quality control
Process optimization
Reference measurements
2.2 Use other than that intended
Use of any other kind than that described in the section Chapter2.1 "Proper use",
page7 and any application that does not comply with the technical specifications
(see Chapter3.6 "Technical data", page14) constitutes use other than that
intended.
In particular, the following applications are not permissible:
Using the sensor in areas for which the sensors are not certified. For certification
details see Chapter3.4 "ATEX rating", page13
Use of the sensor in a potentially explosive atmosphere without an overall
assessment 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
entirely 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 instrument has been developed and manufactured using the latest technological
advances. Nevertheless, risks to persons, property or the environment can arise if the
instrument 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
Risk of explosion from unplugging the device power plug when the power is switched
on.
uDo not unplug the sensor when the power is switched on.

2.6 Staff qualification
Unqualified persons are unable to identify risks and are therefore exposed to greater
dangers.
The device may only be operated by suitably qualified persons.
These operating instructions are aimed at the following target groups:
Users
Users are persons that meet the following criteria:
They have been instructed in the use of the device.
They are familiar with the contents of these operating instructions and the
applicable safety regulations and apply them.
They are able on the basis of their training or professional experience to assess
the risks associated with the use of the device.
Operator
The operator is responsible for the following aspects:
The instrument must be correctly installed, commissioned, operated and serviced.
Only suitably qualified staff may be assigned the task of performing the operations
described in these operating instructions.
The staff must comply with the locally applicable requirements and regulations for
safe and hazard-conscious working practices.
Safety-related incidents that occur while operating the instrument are to be
reported to the manufacturer.
NIR-Online service technicians
Service technicians authorized by NIR-Online have attended special training courses
and are authorized by NIR-Online GmbH to carry out special servicing and repair
measures.
2.7 Personal protective equipment (laboratory)
Depending on the application, hazards due to heat and/or corrosive chemicals may
arise.
uAlways wear appropriate personal protective equipment such as safety goggles,
protective clothing and gloves.
uMake sure that the personal protective equipment meets the requirements of the
safety data sheets for all chemicals used.
2.8 Personal protective equipment (production)
Follow the rules regarding personal protective equipment that are applicable at the
installation site.
The operation of the sensor does not require additional protective equipment.

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
according to wavelength and a silicon photodiode array containing multiple
elements which measure the light intensity for specific wavelength intervals. The
NIR spectrophtometer consists of a diffraction grating to spatially disperse the light
according to wavelength and an indium-gallium-arsenide photodiode array
containing multiple elements.
The produced measurement results 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.
