Switch-Pak™ AX13 High or Low Point Liquid Level Switch with Controller
08208-HW-Flow-0208
Overview
The Switch-Pak™ AX13 is a general-purpose point level switch package designed for high or low liquid level detection with integrated control. It includes a compact 16A relay controller for direct pump or valve shutoff, with an optional flashing alarm for immediate visual notification of alarm conditions. AX13 can be selected based on application media: ultrasonic for chemicals and lightweight oils; vibration for wastewater with light coating or scaling; and buoyancy for clean water and non-coating chemicals.
