A. Product Overview
RTM-ANL-CTDS-CONT-35 is an online Conductivity and TDS Analyzer Controller designed for industrial water quality monitoring and control. It is a single-channel panel mount controller used to measure conductivity and TDS values continuously in water treatment and process water systems.
The controller comes in a 96 x 96 mm panel size, making it suitable for RO control panels, water treatment panels, dosing panels, process automation panels and utility monitoring systems. Its 3.5 inch LCD display allows users to view conductivity and TDS readings clearly during operation.
The instrument supports measurement units such as uS, mS and PPM TDS, depending on the selected range and application. It can be connected with suitable conductivity sensor cells such as 0.01K, 0.1K, 1K and 10K cell options based on the required measuring range.
RTM-ANL-CTDS-CONT-35 is suitable for online monitoring, relay-based control and signal transmission to industrial control systems using analog output.
B. Working Principle
RTM-ANL-CTDS-CONT-35 works by receiving a signal from a conductivity sensor installed in the water line, tank or process liquid system. The conductivity sensor detects the electrical conductivity of the liquid.
Conductivity increases when the amount of dissolved salts, minerals and ions in the water increases. Based on this conductivity value, the controller can also represent the measurement in TDS form as PPM.
The controller processes the sensor signal and displays the measured value on the 3.5 inch LCD screen. The automatic temperature compensation function helps improve measurement stability because conductivity readings change with liquid temperature.
The user can set control limits as per the required water quality range. When the measured conductivity or TDS value crosses the set point, the relay output can operate connected devices such as alarms, dosing pumps, blowdown valves, flushing valves or control circuits.
The 4 to 20 mA analog output can be used to send the measured value to PLC, recorder, data logger, remote display or automation panel.
C. Why It Is Used
RTM-ANL-CTDS-CONT-35 is used to continuously monitor and control water quality in industrial applications. It helps users track dissolved solids and conductivity levels without depending only on manual testing.
In RO plants, the controller helps monitor feed water, treated water and reject water quality. In ETP and STP systems, it helps check process water and treated water conditions. In cooling towers and boiler water systems, it helps maintain dissolved solids within limits to reduce scaling, corrosion and water wastage.
It is also useful for automation because relay output can be used for control action and analog output can be connected with monitoring or control systems.
Main reasons for using RTM-ANL-CTDS-CONT-35 include:
- Continuous online Conductivity and TDS monitoring
- Real-time water quality measurement
