E2405 Series Low Pressure transmitters 2.21

? Low absolute, gauge or differential pressure measurement in HVAC applications? Analog 4-20 mA or 0-10 V output ? Output scale from 50 Pa to 100 kPa (0,5 mbar to 1 bar) ? RS485 Modbus RTU interface option for direct Fieldbus networking

E2405 series differential pressure industrial transmitters are intended formeasurement of low absolute, differential or gauge pressure of airor non-corrosive gases. The main application area is the building automation, eg filter control. The instrument is supplied in several versions with either 4-20 mAcurrent or 0-10 V voltage output and different operation ranges.The sensor output is temperature compensated in the range-10..+60 °C. The analog output scale can be adjusted between 20...100% of the operation range via PC and E2090P kit.A2060-485 digital interface module provides direct RS485Fieldbus networking with Modbus RTU communication protocol.Operating conditions -10...+60 °C, 5...95 %RH Enclosure ABS plastic 58×80×120 mm, wall-mount, IP54 pressure connections for tube with inner diameter Ø4 mm Analog output linear, 4-20 mA or 0-10 V, 3-wire connection Supply 9...30 VDC (versions E2405-I-xx ) 18...30 VDC (versions E2405-U-xx )Version E2405-x-2,5Operation range 2,5 mbar (250 Pa) Accuracy ±0,075 mbar (±7,5 Pa) Diff. pressure max 250 mbar (25 kPa) Static pressure max 700 mbar (70 kPa) Output scale 0-0,5 to 0-2,5 mbar (0-50 to 0-250 Pa) Version E2405-x-12,5 Operation range 12,5 mbar (1250 Pa) Accuracy ±0,25 mbar (±25 Pa) Diff. pressure max 250 mbar (25 kPa)Static pressure max 700 mbar (70 kPa)Output scale 0-2,5 to 0-12,5 mbar (0-250 to 0-1250 Pa)Version E2405-x-100Operation range 100 mbar (10 kPa) Accuracy ±1 mbar (±100 Pa) Diff. pressure max 750 mbar (75 kPa) Static pressure max 2 bar (200 kPa) Output scale 0-20 to 0-100 mbar (0-2 to 0-10 kPa)Version E2405-x-1000Operation range 1000 mbar (100 kPa)Accuracy ±10 mbar (±1 kPa)Diff. pressure max 4 bar (400 kPa) Static pressure max 10 bar (1 MPa) Output scale 0-200 to 0-1000 mbar (0-20 to 0-100 kPa)
