2.1 Description
This instrument is used for the detection of
limit levels in liquids. The measuring principle
is independent of refractive index, density,
conductivity and dielectric constant. The
switches consist of an infrared LED and a
phototransistor. The light of the LED is directed
into a prism. So long as the sensor tip of the
prism is in the gaseous phase, the light is
reflected within the prism to the receiver. When
the liquid reaches the glass tip, part of the light
is refracted into the liquid and only a part of
it is reflected into the prism. With the optional
trimmer the sensitivity of the LED receiver can be
adjusted for different liquids or foam.
The optoelectronic level switches are suitable for liquids such as oils,
water, distilled water, aqueous media and for foam detection (with
trimmer option).
The integrated switch electronics offers an automatic adjustment so
that there is a wide field of application. For the output, there is a pnp
transistor switching output.
