A. Product Overview
RTM-ANL-PHORP-CONT-96F is an online pH and ORP Analyzer Controller designed for continuous liquid quality monitoring and control. It is suitable for applications where pH value or ORP value must be measured continuously and controlled through dosing, alarm or automation systems.
The “F” version is positioned as the flame proof body option in the pH and ORP controller range. This makes it suitable for industrial areas where a more rugged enclosure is required compared to regular panel-mounted controllers. It should be selected based on site safety requirements, enclosure requirement and applicable approval needs.
The controller can be used either for pH measurement or ORP measurement depending on the selected configuration and connected sensor. It supports pH measurement from 0 to 14 pH and ORP measurement from minus 2000 to 2000 mV.
RTM-ANL-PHORP-CONT-96F provides relay outputs for dosing control, alarm control and process interlocking. It also supports 4 to 20 mA retransmission output for signal transmission to PLC, SCADA, recorder or remote monitoring system.
B. Working Principle
RTM-ANL-PHORP-CONT-96F works by receiving the signal from a pH sensor or ORP sensor installed in the water line, process tank, flow cell or treatment system.
For pH measurement, the sensor detects hydrogen ion activity in the liquid and produces a millivolt signal. The controller converts this signal into a pH reading. A lower pH value indicates acidic liquid and a higher pH value indicates alkaline liquid.
For ORP measurement, the ORP sensor measures oxidation reduction potential in millivolts. This helps identify whether the liquid has oxidizing or reducing characteristics. ORP measurement is commonly used in disinfection, chemical dosing, chlorination and oxidation control applications.
The controller uses automatic or manual temperature compensation for pH measurement because temperature can affect pH sensor response. The measured value is displayed on the controller and can be used for control action.
When the pH or ORP value crosses the programmed set point, the relay outputs can operate acid dosing pumps, alkali dosing pumps, oxidant dosing systems, alarms, control valves or interlock circuits. The 4 to 20 mA output can send the process value to PLC, SCADA or data recording systems.
C. Why It Is Used
RTM-ANL-PHORP-CONT-96F is used to continuously monitor and control pH or ORP in industrial liquid processes. It helps maintain correct chemical balance, treatment quality and process safety.
In ETP and STP plants, pH control is important for treatment efficiency and discharge compliance. In chemical dosing systems, the controller helps control acid and alkali dosing automatically. In disinfection systems, ORP monitoring helps verify oxidation strength and chemical effectiveness.
The flame proof version is useful in industrial environments where a stronger enclosure or flame proof body option is preferred for process safety. It is especially relevant for chemical plants, hazardous process areas, solvent handling areas, industrial effluent systems and demanding plant conditions.
