| | | Function The multi Level Switch Series UNS 2000 can be supplied with up to 6 switchpoints (see max. switchpoints). Besides the float operated reed contacts to detect liquid levels, the UNS 2000 can be supplied also with a temperature sensor manufacturer 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) Dimensions B + 40 mm temperature switch (TP) | | |
