DS 401

BD Sensors DS 401 Electronic Digital Pressure Switch with Flush Stainless Steel Sensor with Nominal Pressure of 0 … 400 mbar up to 0 … 600 bar & Accuracy of 0.5% FSO

SKU: DS 401 Category:

The electronic pressure switch DS 401 is the successful combination of intelligent pressure switch with digital display and has been specially designed for universal usage in industry applications; with the flush diaphragm the DS 401 is suitable for the usage in viscous, pasty or highly contaminated media. The rotatable stainless steel globe housing with high functionality and robustness is designed for demanding conditions and difficult installing conditions. As standard theDS 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. Preferred areas of use are plant and machine engineering, environmental engineering (water – sewage – recycling) with meda including water, fuels & oils.
