For use in cryogenic applications, EGE carries inductive sensors of the POLAR series. The series includes high-pressure cleaning and climate change resistant compact devices of the IGMP series for a temperature range of +60 to -60 °C as well as proximity switches of the IGEXP series with remote electronics for use in dust and gas Ex environments (ATEX zone 0/20). All models are made of stainless steel 1.4571 and PTFE, achieve protection class IP68/IP69K and operate reliably even with frequent temperature fluctuations. For an extended temperature range down to -80 °C, EGE also offers sensors of the IGMP S-80 series with remote electronics. Sensors of the POLAR series are ideally suited for use in deep-freeze applications in the food industry, in mobile machinery, in outdoor installations subject to frost, in cryogenic processes or in refrigeration plants. Nominal switching distances between 2 and 15 mm are available, as well as models in M12, M18 and M30 designs. The connection is made via a 2 m FEP cable.
