This new digital float switch uses transistors instead of reeds

By Chemical Engineering |

WIKA

Said to be the first instrument of its kind, this company has launched a float switch with a PNP/NPN output signal. The model GLS-1000 (photo) detects the level of liquids with an accuracy of ≤ 1 mm. The digitized float-measuring principle of the new level switch is implemented using semiconductor sensors. These enable an unlimited number of switching cycles. Users can define up to four switch points with a minimum distance of only 2.5 mm. Thus, the instrument reacts to even the smallest changes in level. At the same time, the GLS-1000 can monitor the temperature of the medium via a temperature output with a Pt100/Pt1000 resistance thermometer. With the GLS-1000, traditional PNP/NPN limit level switches can now also be replaced by a float switch. — WIKA Alexander Wiegand SE & Co. KG, Klingenberg/Germany
