Mode of Operation
The sensor contains IR trans-
mitter, receiver and amplifier
with transistor or SCR output.
The light source is a Ga-As
diode emitting infrared light.
The conical tip of the sensor
forms an angle of 90ºC. This
angle acts as a prism, i.e. the
beam, emitted from the Ga-
As diode placed in one side of
the sensor head, is reflected
internally to the phototransis-
tor placed in the other side of
the sensor head, provided

that the tip of the sensor is si-
tuated in free air. If the sensor
tip is immersed in a liquid,
always having a refractive
index different from air, the
beam will not be refracted by
the prism and the photo tran-
sistor will not receive any sig-
nal.
The sensor types can operate
in oil, waste water, aqueous
solutions such as beer, wine,
alcohol etc. without any kind
of accessory.
