RTM Field Type pH and ORP Analyzer Controller

A. Product Overview

RTM-ANL-PHORP-CONT-96FT is an online pH and ORP Analyzer Controller used for continuous measurement and control of liquid quality in industrial applications. It is suitable for applications where pH or ORP values need to be monitored in real time and connected with dosing, alarm or automation systems.

The controller can be configured for pH measurement or ORP measurement depending on the connected sensor and application. It is suitable for use with pH sensors, ORP sensors, flow cells and protection covers as per site installation requirements.

RTM-ANL-PHORP-CONT-96FT supports measurement of 0 to 14 pH and minus 2000 to 2000 mV ORP. It provides relay outputs for dosing and alarm control and 4 to 20 mA retransmission output for sending the measured value to PLC, SCADA, recorder, data logger or remote monitoring system.

This model is suitable for water treatment panels, chemical dosing panels, effluent treatment systems, process water systems and industrial monitoring panels where online pH and ORP measurement is required.

B. Working Principle

RTM-ANL-PHORP-CONT-96FT works by receiving an electrical signal from a connected pH or ORP sensor installed in the process liquid, tank, pipeline or flow cell.

For pH measurement, the pH sensor detects hydrogen ion activity in the liquid and generates a millivolt signal. The controller converts this signal into a pH reading. A lower value indicates acidic liquid and a higher value indicates alkaline liquid.

For ORP measurement, the ORP sensor measures oxidation reduction potential in millivolts. ORP helps indicate whether the liquid condition is oxidizing or reducing. This is useful in disinfection, oxidation, chlorination and chemical treatment processes.

The controller supports temperature compensation for pH measurement. Temperature compensation helps improve measurement stability because pH sensor response can change with liquid temperature.

When the measured pH or ORP value reaches the programmed set point, the relay outputs can operate dosing pumps, alarm systems, control valves or interlock circuits. The 4 to 20 mA retransmission output sends the measured value to PLC, SCADA, recorder or monitoring equipment.

C. Why It Is Used

RTM-ANL-PHORP-CONT-96FT is used to continuously monitor and control pH or ORP in water and process liquid systems. pH and ORP are important parameters in water treatment, wastewater treatment, chemical dosing, disinfection and process control.

In ETP and STP plants, pH monitoring helps maintain proper treatment conditions and supports discharge quality control. In chemical dosing systems, the controller helps automate acid and alkali dosing. In disinfection systems, ORP monitoring helps track oxidation strength and chemical effectiveness.

This controller reduces manual testing and provides real-time measurement for better process control. Relay outputs can be used for dosing and alarm actions, while the 4 to 20 mA retransmission output helps integrate the reading with plant automation systems.
