DS 400 Intelligent Electronic Pressure Switch Stainless Steel Stainless Steel Sensor accuracy according to IEC 60770: standard: 0.35 % FSO option: 0.25 % FSO Nominal pressure The electronic pressure switch DS 400 is the successful combination of intelligent pressure switch digital display Contacts 1 or 2 independent PNP contacts, freely configurable and has been specially designed for numerous applications in various industrial sectors. Analogue output As standard the DS 400 offers a PNP contact and a display module, which is mounted rotable in the globe housing. Additional optional versions like e.g. an intrinsically safe version, a second contact and an analogue output complete the profile. 2-wire: 4 ... 20 mA 3-wire: 4 … 20 mA others on request Special characteristics ► indication of measured values on a 4-digit LED display rotatable and configurable display module Preferred areas of use are Plant and machine engineering IS-version Ex ia = intrinsically safe for gases and dust welded pressure sensor customer specific versions BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein Environmental engineering (water – sewage – recycling)
