NIVELCO NIPRESS DK-500 Installation And Programming Manual

Thank you for choosing a NIVELCO instrument.
We are convinced that you will be satisfied with our product!
1. INTRODUCTION
The NIPRESS DK−500, DK−600, and DK−700 pressure switches with flush sensor are a successful combination of an
intelligent pressure switch and a 4-digit LED display. This makes it suitable for numerous applications in various industrial
sectors for monitoring and controlling the pressure via switching outputs. It comes with a rotatable display and with PNP contact
outputs. Ex version is also available.
DK-500 series is an electronic pressure switch with Stainless Steel sensor. Excellent for applications in the area of plant and
machine engineering, heating and air conditioning, and environmental engineering (water – sewage – recycling).
DK-600 series is an electronic pressure switch with ceramic sensor. It is suitable for the usage in viscous, pasty or highly
contaminated media. The robust rotatable Stainless-Steel housing is designed for using under rough conditions and in hard
operating environment.
DK-700 series is an electronic pressure switch with welded Stainless-Steel sensor. This pressure switch has been developed
for process industry, especially for food industry and pharmacy.
