Pressure Switch

Contact us for ordering and pricing

There are two independent switches for High and Low control functions. These are solid state and therefore not subject to wear. The switch points are programmed directly from the two front panel buttons and a menu system. Alternatively, the dV-2 PS can be connected via the RS485 link to a laptop/PC, and configured using KELLER’s “Pressure Switch Console” software. User defined configurations can be stored on the computer for future reference. Pressure sequences can also be monitored and recorded on the PC for application diagnostic purposes using KELLER’s Read30 software.

Two independent floating switches are available; neither is subject to wear and they can be operated individually as make or break contacts
