PW15iA
4 Conditions on site
Series PW15iA transducers are hermetically encapsu­
lated and are therefore very insensitive to the influence of
moisture and humidity. The transducers achieve protec­
tion classes IP68 (test conditions: 100 hours under 1m
water column) and IP69K (water at high pressure, steam
cleaning), as per DIN EN60529
1)
. Nevertheless, the
transducers must be protected against the lasting effects
of moisture and humidity.
Important
Note that when using a steam cleaner, the conditions
stated in EN 60529 under degree of protection IP69K
such as max. pressure, max. temperature, etc., must be
met.
4.1 Protection against corrosion
The transducer must be protected against chemicals that
could attack the steel of the housing and base plate, or
the cable.
