1. INTRODUCTION
The NIPRESS DK-300 series is an electronic pressure switch with stainless steel internal or flush sensor. This device is a 2- or 3-wire mini compact pressure switch
with rotatable LCD display for absolute and gauge pressure. It can be ordered with 1 – 4 PNP transistor, 4 – 20 mA or 0 – 10 V output, available in a wide range of
measurement ranges within the -1 – 0 bar and 0 – 600 bar.
The DK-400 series is an electronic pressure switch with welded stainless steel flush sensor. This makes it suitable for numerous applications in various industrial
sectors and is also ideal for viscous or pasty media. This device is a 2- or 3-wire compact pressure switch with rotatable LCD display for absolute and gauge pressure.
It can be ordered with 1 – 4 PNP transistor, 4 – 20 mA or 0 – 10 V output, available in a measurement range of -1 – 0 bar or 0 – 40 bar.
The DK-800 series is an intelligent pressure switch and a digital display with ceramic sensor designed for using in general industrial applications. Its flush diaphragm
version is suitable for the usage in viscous, pasty or highly contaminated media. The standard version comes with PNP contact outputs and a rotatable display.
