2. Design and function
In addition, level control can be carried out with greater precision and filling levels can be
monitored in very small vessels. The sensor thus offers a very wide field of application for
limit value detection.
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 offer an automatic adjustment so that there is a wide field
of application. For the output, there is an pnp transistor switching output.
2.2 Instrument construction
Depending on the switch type, the instruments are fitted with different process connections.
These contain a glass prism and the electronics responsible for the evaluation.
