The float has a magnet inside. The stem incorporates a circuit board with reed switches and resistors placed at regular intervals. For a rising level, float location and reed switches in operation change as shown in Fig.1, from A(2 switches in operation) to B (3 switches in operation), and then to C (2 switches in operation). For a falling level, from C to B, then to A. This means that the combined resistance changes as the float rises or falls. When constant current is applied to terminals 1 and 2 in Fig.2, a voltage proportional to the combined resistance is gained on these terminals. ,,resistive-level-measurement-lr-4072-continuous-level-sensors-for-liquids-features-insensitive-to-process-conditions-such-as-pressure-temperature-and-specific-gravity-various-wetted-parts-material-to-choose-from-for-specific-application-versatile-and-easy-to-use-controller-mp2000-analog-output-2-wire-4-to-20ma-dc-available-as-standard-p-strong-principle-of-operation-strong-p- -h2-style-font-weight-bold-position-static-margin-10px-0px-0px-padding-8px-0px-12px-30px-font-size-14px-color-rgb-69-69-69-background-image-url-quot-img-h2-gif-quot-background-repeat-no-repeat-clear-both-height-20px-font-family-quot-quot-osaka-letter-spacing-0-8px-img-alt-src-http-www-imajteknik-com-tr-uploads-lr_dousa-jpg-style-letter-spacing-0-8px-width-503px-height-205px-h2- -p-nbsp-p- -p-nbsp-p- -p-nbsp-p- -p-nbsp-p- -p-nbsp-p- -p-nbsp-nbsp-nbsp-nbsp-nbsp-fig-2-circuit-in-the-stem-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-ensp-nbsp-nbsp-nbsp-nbsp-nbsp-nbsp-nbsp-nbsp-nbsp-nbsp-fig-1-operation-of-float-and-reed-switches-p- -p-nbsp-p- -p-lr-is-comprised-of-a-float-and-a-stem-the-float-has-a-magnet-inside-the-stem-incorporates-a-circuit-board-with-reed-switches-and-resistors-placed-at-regular-intervals-br- -br- for-a-rising-level-float-location-and-reed-switches-in-operation-change-as-shown-in-fig-1-from-a-2-switches-in-operation-to-b-3-switches-in-operation-and-then-to-c-2-switches-in-operation-for-a-falling-level-from-c-to-b-then-to-a-br- this-means-that-the-combined-resistance-changes-as-the-float-rises-or-falls-when-constant-current-is-applied-to-terminals-1-and-2-in-fig-2-a-voltage-proportional-to-the-combined-resistance-is-gained-on-these-terminals-p- ,1787,0,Resistive level measurement LR
