CONDUCTIVITY TRANSMITTERS, Model : DO 9786T - R1 DO 9766T - R1, Brand : DeltaOhm

DO 9786T/ DO 9766T transmitters convert the output of a conductivity electrode into a signal, with temperature compensation, at 4÷ 20 mA. The electrode input circuit is galvanically insulated against the 4÷ 20 mA output signal. An LCD indicator allows viewing of the process signal value and of the various parameters. The accurate design and choice of components make the instrument precise and reliable for a long working life. The instrument works in conjunction with a conductivity electrode and a temperature probe ( Pt100 sensor, 100 © at 0° C) . Technical characteristics Input conductivity Measuring range 0.0...199.9 mS 2/ 4 electrodes Configurable cell constant 0.01...199.9 cm-1 Transducer energizing Square wave 10...1000 mV, depending on conductivity, 200...1600 Hz, depending on conductivity Input impedance > 100 Mohm Cable length
