Electronic level sensor with guided wave radar for water coolers, oils, oil-based media, water, water-like media

The AF004 Electronic Level Transmitter is equipped with a G 3/4 connection for self-closing and a 360° rotating housing. Since there are no mechanical components, it provides high reliability. The unit contacts the medium via a probe (see accessories), has a 4-digit alphanumeric display and 2 switching outputs (normally open/normally closed programmable). AF004 is suitable for use in aqueous media. The unit cannot be used for fats, granulates, bulk materials, acids, alkalis, hygienic and galvanic applications and highly foaming media

Wherever liquid levels are to be checked, our level sensors are used. Even in critical conditions, our units monitor, for example, unintentional overfilling or emptying of containers, hydraulic tanks, silos, storage tanks
