Bilge Level Switch 10

Introduction Application Where fluids must be stored or handled the Barksdale level switches with their large variety from a simple compact switch to multi level stations with lengths up to three meters are a logic choice (longer on request). When temperature and level measurement are required at the same time in tanks or reservoirs it is practical and economical to combine these in the level switches UNS1000 with temperature sensor and UNS2000 with additional temperature switch. ►Only moving part: The wearlessly working float. ►NO linkage, bellows or dynamic seals to wear, no service or...

General Technical Information The indicated values for power, voltage and capacity are valid for purely resistive loads. Quite frequently though, the loads are surrounded by inductive and capacitive com-ponents. Very often lamp loads must be switched. In this case, protection of the reed switch against voltage and power peaks must be considered. Of course, each case must be evaluated seperately. But we would like to give some guidelines concerning the wiring of reeds for different loads to avoid premature failure. Contact protection is relatively simple for direct current (DC). A free-wheel...

Level Switches The multi Level Switch Series UNS1000 can be supplied with up to 5 switchpoints (see "Max. Switchpoints"). Besides the float operated reed contacts to detect liquid levels, the UNS1000 can be supplied also with a PT100 temperature sensor or with a temperature switch TS. 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, (see "Order code") The min. dimensions are based upon the medium water. Depending on the density of other...
