Permitted ambient temperature range at the electronics housing:
–40 °C ≤ T ≤ +80 °C
a
• Observe the information in the temperature tables.
• In the case of process connections made of polymeric material or with polymeric coatings, avoid
electrostatic charging of the plastic surfaces.
• In the event of additional or alternative special varnishing on the housing or other metal parts:
– Observe the danger of electrostatic charging and discharge.
– Do not rub surfaces with a dry cloth.
• Avoid electrostatic charging of the sensor (e.g. do not rub dry and install outside the filling flow).
Basic specification, Position 5 (Housing) = A
Avoid electrostatic charging of the housing (e.g. friction, cleaning, maintenance, strong medium
flow).
