Description

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.

The minimum differential band is approximately 6 inches (152 mm) in water and varies somewhat with liquid specific gravity. The maximum differential is determined by the length of the displacer suspension cable. Series A15 units are calibrated to operate over a narrow level differential band and are ideally suited for liquid level alarm applications on either high or low level.
