NIVELCO NIPRESS DK-500 Manuals

dkc5127a0600p_01 - 1/5 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. 2.
