Application The transmitters PRE-28.Modbus have two operating modes, configuration mode and Modbus mode. The configuration mode is used for changing settings and detailed diagnostics of the transmitter. In this mode you can also activate a current loop compatible with a 4-20 mA current output. Nominal measuring range (FSO) 0...70 bar (0...7 MPa) 0...16 bar (0...1,6 MPa) 0...2,5 bar (0...250 kPa) 0...1 bar (0...100 kPa) 0...0,25 bar (0...25 kPa) -0,5...0,5 bar (-50...50 kPa) -100…100 mbar (-10…10 kPa) -5...70 mbar (-0,5...7 kPa) Minimum set range 7 bar 1,6 bar 0,2 bar 50 mbar 10 mbar 0,1 bar 10...
