Checks are good, monitoring is even bettei FAFNIR's PTC-resistor level sensor for flammable and non-flammable water-polluting liquids Employee protection and safety management begin as early as the system planning phase. For many years, FAFNIR has been developing high-quality technologies to enable reliable monitoring of liquid levels in tanks and process containers. Our products are stand-alone solutions and operate independently of higher-ranking industrial controllers. System components The FAFNIR level controller comprises a level pick-up with two or three independent sensors and a corresponding number of transducers. One of these sensors can be used, either simultaneously or additionally, as an approved overfill prevention device. The overfill prevention system interrupts the filling process or triggers a visual and audible alarm whenever the maximum permissible level is reached. Typical applications are for full or empty notifications in: 1. Fuel oil tanks, daily service oil tanks, used oil tanks 2. Storage tanks, barrels, bottles Economical and safe The FAFNIR level controller is indispensable for anyone who wants to optimise work processes and meet his responsibility for health, safety and the environment.
