Conductivity Transmitter 4–20mA
This Conductivity Transmitter 4–20mA is an industrial online water quality monitor for continuous measuring water conductivity and temperature. High-precision measuring cell ensures stable reading for pure water, ultrapure water, circulating water and wastewater. Isolated 4–20mA analog output is standard, compatible with PLC, DCS and control system. Optional RS485 Modbus, upper/lower limit alarm, simple calibration, industrial anti-interference design for long-term stable operation.
MTW-cON5200 Conductivity Transmitter 4–20mA is an industrial online device for continuous monitoring of water conductivity and TDS. It matches multiple conductivity electrodes with different cell constants to adapt to ultrapure water, pure water, circulating water and sewage.
Built-in automatic temperature compensation ensures accurate EC reading under fluctuating water temperature. It converts measured conductivity value into standard 4–20mA analog signal, which can be directly connected to PLC, DCS, data recorder and industrial control system for easy signal collection.
Featuring compact panel mounting structure, simple calibration and stable anti-interference performance, it supports long-term 24-hour online operation.
It is widely used in water treatment plants, boiler feed water, pharmaceutical pure water, industrial circulating water and industrial wastewater monitoring.
