ABB - Model MS10 - Electric Level Switch - Datasheet

The MS10 is a single-pole, double-throw electric switch capable of sensing the liquid level inside a process vessel. The unit is typically mounted via the integral 1-1/2” MNPT connection. Several standard adapters are available for use when a 1-1/2” FNPT is not available on the vessel. The MS10 requires no preventative maintenance as it is totally sealed. The MS10 provides either a normally open or normally closed dry contact to activate external devices such as alarms or solenoids. Variations in process fluid specific gravity have minimal effect on the level measured because of the small size of the integral float.
