RTM Online Conductivity and TDS Controller 96x96 Panel Mount

A. Product Overview

RTM Online Conductivity and TDS Controller 96x96 Panel Mount is a panel-mounted instrument used to measure and control conductivity or TDS in industrial water systems. It is suitable for applications where continuous monitoring of dissolved solids, water purity and process water quality is required.

The controller is designed in a compact 96x96 mm panel size, making it suitable for electrical panels, RO control panels, water treatment panels and industrial automation panels. It can be configured as a conductivity controller or TDS controller depending on the application requirement.

The instrument accepts conductivity cell input and PT-100 temperature input for temperature compensation. It provides relay output for control action, 4 to 20 mA analog output for signal transmission and RS-485 Modbus RTU communication for integration with PLC, SCADA and remote monitoring systems.

This makes the RTM Online Conductivity and TDS Controller useful for both standalone control and plant-level automation.

B. Working Principle

The RTM Online Conductivity and TDS Controller works by taking input from a conductivity cell installed in the water or process liquid line. The conductivity cell measures the electrical conductivity of the liquid, which indicates the concentration of dissolved ions present in the water.

Higher conductivity generally means higher dissolved solids, salts or mineral content. Lower conductivity generally indicates purer water with fewer dissolved solids.

The controller receives the signal from the conductivity cell and converts it into a displayed conductivity or TDS value. With PT-100 temperature input, the controller can compensate for temperature variation because conductivity readings change with liquid temperature.

Based on the programmed set points, the controller can activate relay outputs for control functions such as dosing, flushing, blowdown, alarm indication or process interlocking. The 4 to 20 mA output can be connected to PLC, recorder or control system, while RS-485 Modbus RTU can be used for digital communication and online data monitoring.

C. Why It Is Used

RTM Online Conductivity and TDS Controller is used to maintain correct water quality in industrial and process applications. It helps operators continuously monitor conductivity and TDS instead of relying only on manual testing.

It is commonly used to check whether water quality is within the required limit. In RO plants, it helps monitor treated water quality and reject water condition. In ETP and STP plants, it helps track dissolved solids in process and treated water. In cooling towers and boiler water systems, it helps control dissolved solids to reduce scaling, corrosion and water wastage.

The controller is useful where automatic control is required. Relay outputs can be used for alarm or control operation, while analog and RS-485 outputs help connect the instrument with automation systems.

Main reasons for using this controller include:

1. Continuous online conductivity and TDS monitoring
2. Better control of RO, ETP, STP and WTP water quality
3. Reduced manual checking and operator dependency
4. Relay-based control for alarm, dosing or blowdown
5. Integration with PLC, SCADA and data logging systems
6. Temperature-compensated measurement using PT-100 input
7. Compact 96x96 panel-mount design for control panels
