SITA Messtechnik GmbH - Operating Instructions SITA ConSpector
SENSOR HEAD
Connecting line:
connects the sensor head with the basic unit
secures the sensor on the counterpart of the stand
Immersion probe:
The immersion probe is immersed approximately to the
middle of the probe into the liquid to measure the con-
tamination level.
(see also section 4.2)
This is a part of the immersion probe. Limits the effective
space of the UV radiation thereby creating a defined liquid
space.
4.2 Immersion probe
The immersion probe on the sensor head of the SITA ConSpector is equipped with a light conductor
on the inside through which the excitation radiation is emitted into the liquid. The fluorescence
radiation excited in the defined liquid space at the end of the immersion probe is conducted via
the light conductor into the sensor head and from there to the photodiode.
The immersion probe and thus also the light conductor are chemically resistant against the effect
of organic, acid and alkaline solutions. The immersion probe consists of stainless steel (1.4301),
quartz glass and Viton. Avoid prolonged contact of the immersion probe hydrofluoric acid and hot
phosphoric acid, strong alkaline solutions (pH 12) and phosphates.
Avoid mechanical loads or mechanical damages of the light conductor.
Remove the limiter only to clean the immersion probe since it protects the
visible part of the light conductor against mechanical damages.
To connect the connecting line with the basic
unit, make sure the socket and the plug are
properly aligned (see section 5).
Make sure to regularly clean the immersion
probe, the limiter and especially the visible
part of the light conductor from contamina-
tion (see section 8.1
). Do not look directly into
the ray outlet opening while measuring is in
progress.
