Compact, rugged and low-maintenance point level switch with easy handling.

The GRF18S is a compact optical level switch which is characterized mainly by its extremely simple commissioning. The proven technology of the energetic photoelectric proximity sensor from SICK is the foundation for the sensor. This allows for easy, rugged and reliable sensor construction. Thanks to the use of high-quality materials such as stainless steel 1.4404 and polysulfone as well as the housing design in enclosure rating IP69, the GRF18S guarantees high process reliability, even under harsh ambient conditions outside the tank. Quick and problem-free commissioning, without medium calibration, reduces not only commissioning costs, but also maintenance. Due to the optical technology, the GRF18S is particularly well-suited for water-based media.
