Level switch

New reverse assembly option for LBFS frequency-sweep level switch

The new standard version of Baumer’s LBFS level switch is made from AISI 304 or 316 stainless steel and comes with a PEEK sensor tip. In addition to this, Baumer now provides the LBFS with special G½ process connections for reverse assembly. These options broaden the field of possible applications of the LBFS. Based on the novel frequency-sweep technology, the level switch is suitable for measuring the levels of viscous or dry substances as well as liquids with a repeatability and hysteresis of ± 1 mm and a typical response time of 0.2 seconds. As the LBFS is unaffected by flow, turbulence, bubbles, foam, and suspended solids, it is particularly suitable for level detection in processes generating those.

The new G½ connection for the LBFS allows for two types of reverse assembly. The first makes it possible to mount the level switch from the inside of a tank using the included fibre gasket and a G½ nut. Fields of application include low level and leakage detection in tanks for oil or cooling fluid used in pneumatic systems or high-speed cutting (HSC) machines.

The second reverse assembly option enables the LBFS to be mounted in a simple G½ thread inside a tube to extend the length of the sensor. A fibre gasket and an M12 plug or 5-metre cable are included with the measuring device. With the tube functioning as an adjustable extension rod, the LBFS can be adjusted to changing levels. This makes it possible to use the LBFS as a float-type level switch in applications such as automatic dosing systems as well as for phase separation in the petroleum industry, hydraulic systems, and water/wastewater treatment.
