The dV-2 PS is a sophisticated digital pressure gauge with two independent pressure switch outputs. The gauge employs KELLER’s proven microprocessor technology which produces highly accurate results. All readings are linearised and temperature corrected, to give an accuracy of 0,2 %FS. 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. The switch can provide a window function or be utilised as a hysteresis switch. These switching functions enable the dV-2 PS to assume control tasks. Respective switch output status is displayed on an LED located on the front.
