Woerner KFI-O LEVEL SWITCH

Function - Thermostat: For liquids level detection in reservoirs and agent temperature monitoring. The guide tube is connected to the flange by means of a cutting-ring union. Thus it is possible to shorten subsequently a tube which is too long. Upon reaching the firmly set response temperature, a bimetal disk that can be influenced by the temperature will switch (see Order designation). The thermostat ist situated in the lower part of the conductor piece and can be exchanged. CU-alloy For inductive an capacitive loads, suppressor circuits shall be provided for. (Diode, RC element, varistor) In the guidance pipe there are three switching elements at maximum locked on a hole strip with hole spaces of 10 mm. The switching function is bi-stable. When turning the contacts by 180°, the switching function can be reversed (the opener contact becomes the closer contact and vice versa). By loosening the cap screws the switching elements can subsequently be changed in their functions and replaced.
