For ambient temperatures -40 ... 85°C (-40 ... 185°F) the
information based on the temperature classes in the
associated certificates, must be complied with.
The temperature sensor circuit (Pt100) and the digital output
(pulse / limit value output) must be connected in accordance
with the requirements of the Ex certificate.
WARNING - General danger for Model 266
used in Zone 0!
The housing contains aluminum, which can lead
to a potential danger of ignition through impact or
friction. For this reason, impact or friction must be
avoided during installation and use.
