The electronic pressure switch DS 400 is the successful combination of — intelligent pressure switch — digital display and has been specially designed for numerous applications in various industrial sectors. As standard the DS 400 offers a PNP contact and a display module, which is mounted rotable in the ball housing. Additional optional versions like e.g. an intrinsically safe version, a second contact and an analogue output complete the profile. Features: — nominal pressure: 0 ... 100 mbar up to 0 ... 600 bar — accuracy: 0.35 % (opt. 0.25 %) FSO — indication of measured values on a 4-digit LED display — rotatable and configurable display module Optional Features: — IS-Version Ex ia = intrinsically safe for gases — pressure sensor welded — customer specific versions

The electronic pressure switch DS 200 is the successful combination of — intelligent pressure switch — digital display and has been specially designed for applications in various industrial sectors. As standard the DS 200 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 ... 600 bar — accuracy: 0.35 % (opt. 0.25 %) FSO — indication of measured values on a 4-digit LED display — rotatable and configurable display module — 1, 2 or 4 independent PNP contacts, freely configurable — configurable contacts (switch on / switch off points, hysteresis / window mode, switch on / switch off delay) Optional Features: — IS-version Ex ia = intrinsically safe for gases — pressure sensor welded — customer specific versions

The pressure transmitter DMP 457 has been especially designed for rough conditions occurring especially in shipbuilding and offshore applications. All gaseous and liquid media, which are compatible with stainless steel 1.4404 (316L) respectively can be used. Sensor element is a piezoresistive stainless steel sensor with high accuracy and excellent long-term stability. In order to meet the special requirements for shipbuilding and offshore applications extensive tests had to be passed to get the LR, Germanischer Lloyd (GL), Det Norske Veritas (DNV) and China Classification Society (CCS) approvals. Features: — nominal pressure: 0 ... 100 mbar up to 0 ... 600 bar — accuracy:0.35 % (opt. 0.25 %) FSO — shipping approvals: LR, DNV, GL, ABS, BV, CCS — flush pressure port G 1/2" from 100 mbar — excellent thermal behavior Optional Features: — IS-Version Ex ia = intrinsically safe for gases and dusts — welded pressure port
