Differential pressure transducer TDK6 sends an electrical signal proportional to the difference of value between two pressures. Two versions are available: the first execution has the M3 electric connector with output signal 4 – 20 mA; the second execution has the M12 connector with 4 – 20 mA output signal and 2 temporized signal alarms, set at 16 mA and 20 mA. The maximum allowable pressure is 420 bar and the differential pressures are available from 1 to 9 bar. All the parts on contact with the fluid are made of brass, or stainless steel on request.
