Pantech's Two Wire Transmitters, model 874 is designed over low drift low power components.It pumps in a constant current into the liquid through the conductivity cell to measure the electrical conductivity of any liquid. The square wave signal is selected as an excitation voltage for the conductivity cell for the ease for processing. It provide 4-20mA dc signal on the same two wire which carry the 24 V DC for conductivity measurement. The transmitter is an ideal choice for Linearized measurement with standard conductivity cell. Temperature of the liquid is monitered by a RTD element and compensation is provided over the complete operating range. It provides a current output signal of 4 20 mA DC capable of driving a load of upto 650.
