5.1.1 Connecting
As a standard the cooled housing is supplied with fittings and non-metric 1/8" NPT threads. If you
intend to supply the cooling media through pipes or hoses, consider the following information.
Thread Adapter - metric pipe to NPT inside thread
Thread Adapter - inch-type pipe to NPT inside thread
Supporting tube for PVC or Tygon hoses
5.1.2 Avoidance of Condensation
If environmental condition makes water cooling necessary, it is strictly recommended to check whether
condensation will be a real problem or not.
Water cooling also causes a cooling of the air in the inner part of the device. Thereby the capability of
the air to store water decreases. The relative humidity increases and can reach 100% very quickly. In
case of a further cooling, the surplus water steam will come out as water (condensation). The water will
condense on the lenses and the electronics resulting in possible damage to the sensor. Condensation can
even happen on an IP65 sealed housing.
There is no warranty repair possible in case of condensed water within the housing!
To avoid condensation, the temperature of the cooling media and the flow rate have to ensure a
minimum device temperature. The minimum device temperature depends on the ambient temperature
and the relative humidity, please consider the following table.
