Immersion fittings<br />
Series 202820<br />
Brief description<br />
Immersion fittings are used for holding electrochemical sensors (e.g. pH and redox electrodes,<br />
glass conductivity cells, compensation thermometers etc.) with a Pg13.5 screw-in<br />
thread and a fitting length of 120mm.<br />
Fitting types for up to 3 sensors are available.<br />
The fittings are mounted in open sluices or containers. They protect the installed sensor<br />
from breaking and enable measurement in different immersion depths. Thanks to various<br />
options and accessories, the fittings can be optimally adjusted to the conditions on site.<br />
Two pipe clips for wall mounting are provided for the standard versions, but sliding flanges,<br />
which are available as an option, also permit installation in container lids, for example.<br />
The following points have to be taken into account:<br />
■ The fittings must be readily accessible, to ensure that the sensor can be cleaned and<br />
serviced at regular intervals.<br />
■ pH and redox electrodes must not be allowed to remain dry for a prolonged period -<br />
this can be prevented by using a wetting cup.<br />
■ The suitability of the materials (e.g. chemical compatibility) has to be tested by the<br />
system designer.<br />
