The capacitive keyboards at Hoffmann + Krippner provide best qualifications for the particular applications of industrial food processing environments in order to fulfill the requirements of a robust yet easy to clean control unit. Capacitive systems can be optionally incorporated behind glass, plastic, or other non-conductive surfaces and are thus protected from acids, dirt and other miscellaneous contaminations.
Operation is possible with only a light contact on the flat surface. A capacitive rotary encoder identifies and then directly transfers actuation signals to the machine control through an interface. The digital display can be freely programmed in order to ensure individual assignment of diverse measurement parameters.
The individual tolerance values are manipulated by activating a confirmation button and then adjusted according to current task requirements. In order to prevent operating errors, the control unit must be operated using both hands. Possible interferences and external influences are identified and consequently eliminated by the processor and the associated software. Visual and/or acoustic indicators compensate for the missing tactile feedback capacitive displays are known for.
