This can destroy the sensor.
1.2 Use in areas subject to explosion hazards
– Equipment and components which are used in explosion-hazard areas and
which have been inspected and approved in accordance with international or
European explosion-protection regulations may be used only under the
specified conditions.
– In applications, which require devices of category 1G (zone 0) resp. EPL Ga,
intensive electrostatic charging processes have to be prevented.
– Not for use in oxygen enriched atmospheres, i.e. more than 21 Vol% oxygen.
– If fitted at the time of delivery, or retrofitted at a later stage, with the relay module
and/or the pump module, the device loses its explosion protection approval.
Operation of the device with the pump module and/or the relay module installed
is not permitted in explosion-hazard areas.
– When measured gas is aspirated from explosion-hazard areas, suitable
explosion protection measures are required, e.g. use of flame arresters.
1.3 Electrical installation
– The relevant regulations for routing and connecting of power and signal lines to
gas detection systems must be strictly adhered to.
