JUMO dTRANS pH 02 Analytical Transmitter Controller

Overview

JUMO dTRANS pH 02 is a compact multichannel transmitter and controller for analytical measurement, controlling and recording pH value, redox potential, ammonia (NH3) concentration, temperature, and flow rate. Configurable as a two-state, three-state, three-step, or continuous P, PI, PD, or PID controller, the JUMO dTRANS pH 02 is the current-generation successor within JUMO’s compact analytical indicator/controller platform, replacing the earlier dTRANS Az 01 series with an updated modular design and expanded input/output flexibility.

As the official authorized partner and exclusive regional representative for JUMO, Seven Star LLC proudly supplies the JUMO dTRANS pH 02 to water treatment facilities, chemical dosing systems, and process industries across Oman and the GCC. Customers purchasing through Seven Star LLC receive full manufacturer warranty, genuine JUMO hardware, and technical support based in the Sultanate of Oman, avoiding the compliance and support risks of unauthorized grey-market channels.

Measurement Principle

The JUMO dTRANS pH 02 accepts a main input from a pH combination electrode or redox sensor, measuring the small millivolt potential generated at the sensor membrane and converting it into a calibrated pH or redox value using stored calibration coefficients. An additional analog input accommodates a compensation thermometer or a second process variable such as ammonia concentration or a standard 0(4)–20 mA / 0–10 V signal, while two binary inputs support flow-pulse counting or external interlocks, giving the instrument the flexibility to serve as a combined measurement and control point for a treatment or dosing process.

Once the process value is acquired, the instrument’s internal control algorithm – selectable between two-state, three-state, three-step, or continuous P, PI, PD, or PID modes – drives up to seven relays or three analog outputs to actuate dosing pumps, valves, or alarm circuits. Because the measurement itself is electrochemical rather than mechanical, there is no moving part in the sensing path to wear, and the JUMO dTRANS pH 02‘s calibration logbook and electrode-monitoring function give operators a documented, traceable record of sensor health over time.

Engineering Design of the JUMO dTRANS pH 02

The JUMO dTRANS pH 02 is housed in an ultra-compact enclosure suited to either a panel cutout or a surface-mounted control cabinet installation, with a front panel rated IP65 to resist wash-down and dust ingress in industrial water treatment areas. The plain-text display supports 13 integrated user languages and offers a choice of large digits, bar graph, or trend visualization, allowing operators across regional plant teams to read the process state without needing to memorize numeric codes.

Electrically, the base unit provides one main input, one analog input, and two binary inputs, with up to three expansion slots accepting analog output, relay, or PhotoMOS® relay option boards to scale the instrument’s output count up to seven relays or three isolated analog outputs. A wash timer function automates periodic cleaning cycles for self-cleaning or spray-cleaned electrodes, and the built-in math and logic module allows derived process values – such as a combined pH/ORP dosing interlock – to be computed directly within the transmitter rather than in an external PLC.

Key Features

The JUMO dTRANS pH 02 combines analytical measurement and closed-loop control in a single compact instrument. Key characteristics include:

• Multichannel measurement of pH, redox potential, ammonia concentration, temperature, and flow within one device.
• Selectable two-state, three-state, three-step, or continuous P, PI, PD, and PID control functions for dosing and detoxification processes.
• Ultra-compact housing suitable for panel or surface-mounted control cabinet installation, rated IP65.
• Choice of display visualization – large digits, bar graph, or trend – with 13 integrated user languages.
• Up to three analog outputs and up to seven relays across three optional expansion slots.
• Built-in math and logic module for derived process calculations without an external controller.
• Wash timer function to automate cleaning cycles for self-cleaning or fouling-prone electrodes.
• Integrated calibration logbook and electrode-monitoring for documented sensor traceability.

Industrial Applications

The JUMO dTRANS pH 02 is widely deployed in chemical dosing and neutralization systems, cooling water treatment, wastewater detoxification, and process industries where pH, redox, or ammonia control directly affects product quality or regulatory compliance. Its continuous PID control capability makes it well suited to closed-loop detoxification and pH-adjustment skids, while the wash timer and electrode-monitoring functions reduce maintenance intervention in fouling-prone process streams such as cooling tower makeup water and industrial effluent treatment.

As the officially authorized partner for JUMO, Seven Star LLC distributes the JUMO dTRANS pH 02 to desalination plants, district cooling operators, and industrial water treatment facilities throughout Oman and the wider GCC, including operations within the Sohar and Salalah economic zones. Regional customers benefit from local stock availability, calibration support, and direct access to JUMO’s engineering documentation through Seven Star LLC’s technical instrumentation division.
