Baumer LFFS Level Sensor family.Baumer’s level switch LFFS detects the level of liquids, viscous fluids, and even dry media. For particularly difficult materials like adhesive substances, the teach-in function enables a manual adjustment of the level to be detected. The switching status can be chosen as normally open or normally closed. The output type can be user set to PNP, NPN, or digital out. All wetted parts are made of FDA-approved stainless steel or PEEK thermoplastic, and the unit has earned 3A approval. For the use in open or closed tanks, the device withstands a pressure of up to 580 psi (40 bar). Since the switch does not contain any moveable parts and its electronic unit is completely integrated, it is practically maintenance-free.

Baumer’s level switch LFFS is suitable for high process temperatures of up to 200 °C. A bright blue light on top of the switch shows when a media is detected. The indication can be seen easily even if the sensor is mounted on top of a tank. The process connection makes it suitable for food and beverage industry applications. For the use in hazardous areas, different ATEX versions are available. It can be easily configured on PC via the FlexProgrammer 9701.

When used with a cooling neck, the level switch is suitable for process temperatures from -40 to 200 °C. The optional sliding connection is available in 100 and 250 mm length and can serve as a cooling neck or extension, for example if the medium has to be reached through the tank insulation or the level detection has to be adjusted to a certain height. In the standard version, the LFFS is designed for permanent process temperatures from -40 to 85 °C as well as for the use in CIP and SIP facilities with short-term temperatures of up to 140 °C (max. one hour).

For applications in gaseous and dusty surroundings, the LFFS is available in different ATEX versions which enable a safe level detection of explosive gas or dust mixtures. The ATEX certifications cover the zones 0, 1, and 2 as well as zones 20, 21, and 22.
