Electronical pressure switch MagSwitch with integrated LED
The compact electronic pressure switch MagSwitch provides pressure monitoring. Adjusting screws are used to set the switching point whilst under pressure. Integrated LEDs indicate the current switching state.
The principle of non-impact measurement based on the Hall-effect produces a pressure switch which has a high level of repeatability and durability, even in the case of a high number of pressure cycles.
The contact functions (normally open / normally closed) and the contact types (p-switching / n-switching) are available as optional extras. Switching currents ranging from a few Micro-Amps to 100mA allow the MagSwitch to be easily integrated into almost any control system. The adjustable hysteresis enables to build up 2-position controllers easily without additional external components.
A pressure connection free of elastomers qualifies the MagSwitch for many liquid and gaseous media.
The metal diaphragm can also be used without any problem for simultaneously occurring pressure and vacuum.

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.
