 | Displacer switches – single, dual and tri-switch series Single-Stage Switches Series A10 displacer type level measurement units are wide differential units calibrated to actuate as a liquid level reaches a given displacer and to deactuate when the level reaches a second displacer. Single stage, wide differential displacer switches are factory calibrated yet field-adjustable to operate over a wide level differential band. | Dual-Stage Switches Series B10 displacer type level measurement units are wide differential tandem switches that are factory calibrated with a choice of several switch operating sequences designed to meet virtually any application. Tri-Stage Switches Series C10 displacer type level measurement units utilize three electrically separate control signals in a selected sequence in response to liquid level changes. | DATA SHEET |
