Handling of the sensor cap

z Dirt and moisture below the sensor cap can have

negative influences on the function of the sensor
and decrease lifetime of the sensor cap. Please
pay attention to clean and dry working environ­ment, when taking off the senor cap.

z Please do not touch the outer sensor membrane

with your fingers. Touch the sensor cap principally
only at the sides (arrows in the figure on the left).

z Avoid strong mechanical forces on the sensor

membrane (pressure, scratches).

z The impact of light, particularly daylight, on the

inner side of the sensor cap will have, over time,
an impact on the measuring properties and can
shorten the lifetime of the sensor cap. Therefore,
the inner side of the sensor cap should not be
exposed to direct sunlight. Please only store sen­sor caps in light protected environments.

Installation

Replace the O-ring each time when replacing the
sensor cap. Refer to the sensor operating manual
