Level Switches The multi Level Switch Series UNS2000 can be supplied with up to 6 switchpoints (see max. switchpoints) and with a length of max 3000 mm. Besides the float operated reed contacts to detect liquid levels, the UNS 2000 can be supplied also with a temperature sensor and/ or temperature contact(s), which are to handle as switchpoint(s) please note max. switchpoints! A wide selection of mounting elements, electrical connections, various materials and options allow you to "design" your own switch, within the given dimension limits, for your particular application. Very long units or large flanges can cause high shipping and installation costs and "split" versions might be the answer. Consult us for the best combination. The min. dimensions are based upon the medium water. Depending on the density of other fluids this dimension can vary several millimetres. The contact modes (NO or NC) are defined on the basis of an empty tank and for installation through the top or through the bottom (when specified as "-U"). When not specified otherwise we will set the switch position for density 1 (water) and the switch action to be on moving upward. Temperature sensor (PT100) and/ or the temperature switch, a Bi-metall hermetically sealed element, are installed only in the bottom of the stem. That means: Dimensions B + 10 mm with temperature sensor PT100) = BPT Dimensions B + 40 mm temperature switch (TP) = BTP Technical Data 40 bar, depends on mounting element and float -10 °C...+105 °C, PVC-cable -40 °C...+150 °C, Silicone cab.(-HT; ATEX Exi limited to -40°C...+75 °C) and KL6 / KL12 Min.
