Multirange 2-wire 4-20 mA transmitter 6720 Thermocouples B,C,D,E,G,J,K,L,N,R,S,T RTD-sensor Pt100 mV-input -100 .. +100 mV Process inputs: 0..20mA, 4..20 mA, -20 .. +20 mA, 0..5 V, 0..10 V and -10 ..+10 V Thermopile IR-sensors Programmable by PC Input- Output isolation 2 kV Digital filter 2-wire output 4..20 mA High accuracy 0.05% of span Thermocouples: Sensor Range Transmitter 6720 is exceptionally versatile and accepts all most common sensor inputs. You can configurate it by PC via Cable POL-RS232. Transmitter front has configuration connector which connects adapter cable POL-RS232 to serial port of the PC. Menu based configuration program is easy to use and together with low cost cable makes delivery economical even in case of one unit only. The 16 bit A/D converter enables high measuring accuracy. Linearity of A/D converter is 0.008% and resolution of output signal 0.03% of full scale (12 bit DAC). Galvanic isolation is specially important with thermocouples but potential differencies with other measuring circuits can be avoided also with process input signals. Transmitter is fast to install and its flexibility opens new possibilities in industrial and maintenance measurements. The 2-wire connection is easy and versatile to use in all applications. Small size of the case (22.5 x 60 x 75 mm) helps comissioning in narrow spaces.
