DS 401 Intelligent Electronic Pressure Switch Stainless Steel Ceramic Sensor accuracy according to IEC 60770: 0.5 % FSO Nominal pressure The electronic pressure switch DS 401 is the successful combination of and has been specially designed for universal usage in industry applications; with flush diaphragm the DS 401 is suitable for the usage in viscous, pasty or highly contaminated media. The rotatable stainless steel globe housing is predestined for rough conditions and difficult installing conditions, caused by the high functionality and robustness. As standard the DS 401 offers a PNP contact and is optionally available with a second, independent contact. Additionally the DS 401 could be equipped with an analogue output. 1 or 2 independent PNP contacts, freely configurable Analogue output 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 Environmental engineering (water – sewage – recycling) IS-version Ex ia = intrinsically safe for gases and dust pressure port PVDF intelligent pressure switch digital display customer specific versions BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
