Pressure Switch DS 400

The electronic pressure switch DS 400P is the successful combination of — intelligent pressure switch — digital display and has been developed for process industry; especially for food industry and pharmacy. As standard the DS 400P offers a PNP contact and a rotable display module with 4-digit LED display. Optional versions like e.g. an intrinsically safe version, max. 2 contacts and an analogue output complete the profile. Features: — nominal pressure: 0 ... 100 mbar up to 0 ... 40 bar — accuracy: 0.35 % (opt. 0.25 %) FSO — 1 or 2 independent PNP contacts, freely configurable — indication of measured values on a 4-digit LED display — rotatable and configurable display module — hygienic process connections with flush stainless steel diaphragm Optional Features: — IS-version Ex ia = intrinsically safe for gases

The DS 233 is a differential pressure switch with digital display for non-aggressive gases and compressed air. Because of its compact and robust aluminium housing it is particularly suited for machine and plant engineering. Basic element of the DS 233 is a piezoresistive silicon pressure sensor, which features high accuracy and excellent long term stability. As standard the DS 233 offers a PNP contact and a rotatable display module with 4-digit LED display for representing the differential pressure. Optional up to 2 freely configurable contacts are available. Features: — nominal pressure: 0 ... 6 mbar up to 0 ... 1000 mbar — accuracy: 0.35 % FSO — aluminium housing — rotatable and configurable display module — 4-digit LED display — suited for non-aggressive gases and compressed air Optional Features: — 1 / 2 PNP contacts — customer specific versions

Features: — nominal pressure: 0 ... 6 bar up to 0 ... 600 bar — accuracy: 0.5 % FSO — 1 analog output and up to 2 contacts — display and housing rotatable — perfect for oxygen applications

The electronic pressure switch DS 200P is the successful combination of — intelligent pressure Switch — digital Display and is suitable for the usage with viscous and pasty media. As standard the DS 200P offers a PNP contact and a rotatable display module with 4-digit LED display. Optional versions like e.g. an intrinsically safe version, max. 4 contacts and an analogue output complete the profile. Features: — nominal pressure: 0 ... 100 mbar up to 0 ... 40 bar — accuracy: 0.25 % / 0.35 % / 0.5 % FSO — rotatable and configurable display module — indication of measured values on a 4-digit LED display — configurable contacts (switch on / switch off points, hysteresis / window mode, switch on / switch off delay) Optional Features: — analogue output — IS-Version Ex ia = intrinsically safe for gases — customer specific versions
