Pantech Instruments manufactures Conductivity 2-Wire Transmitter, Model 874. Pantech Instruments is the manufacturer and exporter of Process Control Instruments. Conductivity 2-Wire Transmitter includes pump in a constant current into the liquid through the conductivity cell to measure the electrical conductivity of any liquid. Conductivity 2-Wire Transmitter has a square wave signal which 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 wires, which carry the 24 V DC for conductivity measurement. The Conductivity 2-Wire 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.
Conductivity 2-Wire Transmitter provides a current output signal of 4 - 20 mA DC capable of driving a load of up to 650 omega. Conductivity 2-Wire Transmitter can be selected by setting the DIP switches on the module and with proper cell constant. The temperature compensation provided as standard is 2 percent degree Celsius but can be changed to a value anywhere between 0 to 4 percent. The Conductivity 2-Wire Transmitter is available in field mounted housings with or without local display. The local 3- fraction 1/2 digit loop powered display reduces the load capability of the transmitter to around 500 omega. The Conductivity 2-Wire Transmitter is available in weather or explosion proof housing.
