CAUTION
Note the full range of environmental influences to which
the sensing head may be exposed. Avoid external
influences such as splashwater, oil, corrosive aerosols
(salt spray) etc. and the possibility of mechanical
damage.
The gas inlet area of the sensor must be protected
from water, dust and mechanical damage and kept
clear of dirt. Do not allow paint to block the gas inlet if
painting is conducted in the area.
Multiple EC sensing heads remote must not be
connected in series.
NOTICE
The EC measuring sensor wall and pipe mounting
accessory set (order no. 45 44 213) is required to
mount the EC measuring sensor on a wall or pipe.
The sensing head should be mounted at a low-
vibration location at even a temperature near
a potential leakage point (avoid direct sunlight).
NOTICE
Observe the direction of the remote connector!
