5.2 ATEX Notes
Guideline
2014/34/EU
, known as the ATEX directive of the European Union , requires in Annex II to the fulfil-
ment of basic safety requirements for devices that are provided within the EU for use in potentially explosive
atmospheres.
The sensor head of the spectrometer has the following ATEX-characterisation
∗
:
II 3/- G Ex op is IIA T4 Gc/-
Danger:
The spectrometer sensor module must absolutely be located outside the explosion-
endangered area.
Warning:
The supply voltage must not be applied to the housing of the spectrometer sensor
module, the housing of the spectrometer sensor module must always be grounded.
Danger:
The electrical resistance between the lower lug of the sensor head and the grounding
screw of the spectrometer sensor module must be less than 50 Ω.
Parameter:
Electrical data:
maximal input voltage of the sensor module:
36 VDC
Range of ambient temperature:
Sensor head:
0 °C to +110 °C
Sensor module:
0 °C to +40 °C
Special conditions for safe use:
The ambient temperature of the sensor is 0 °C to +110 °C.
The sensor module must be installed outside of explosion-endangered areas.
The ambient temperature of the sensor module is 0 °C to +40 °C.
The basic safety and health requirements are fulfilled by compliance with:
DIN EN 60079-0:2014-06
General requirements
DIN EN 60079-28:2016-04 Optical Radiation 'op is'
Identification of the sensor head:
Laser engraving
Identification of the spectrometer sensor
module: abrasion resistant label on the
