Conductivity monitoring in liquid processes is easier when the measuring cell, compensation and digital communication are combined in one compact device. CONDIX4613 measures specific conductivity and temperature, then provides process values, parameters, identification data and diagnostic data to a master such as PLC or SCADA via RS485 with MODBUS RTU.
The 4-electrode principle with cell constant C = 0.4 1/cm covers applications up to 200 mS/cm. It is resistant against pollution and not influenced by polarization effects or wire resistance, supporting reliable measurement in landfill seeping water, seawater and black water treatment on ships.
Installation uses pipe thread DIN ISO 228 (DIN 259; BSP), with G 1/2 A process connection and pressure up to max. -1..16 bar. Parameters can be adjusted via the interface or SENSware, while six selectable temperature compensation types help match the liquid.
Measures conductivity of liquid media and records temperature with an integrated Pt1000 measuring element.
Integrated digital transmitter — Submits values and parameters to a master such as PLC or SCADA.
RS485 Half-Duplex interface with MODBUS RTU and selectable baud rates of 1200, 2400, 4800, 9600 and 19200
Device parameters and input configuration can be adjusted via the interface, SENSware configuration software or MULTICON-H.
Selectable modes include no compensation, linear coefficient, natural waters, ASTM-D1125 ultra-pure water, NaCl diluted solution, ASTM-D5391 acidic pure water and ASTM-D5391 alkaline pure water.
Process material consists of PVC-U, casting resin and graphite electrodes.
8 pole round connector plug with brass nickel plated design.
LEDs indicate supply voltage, bus communication and addressing status.
