ORP6040 ORP Sensor, pH ORP Sensors for Industrial, Laboratory, and Daily Usage
Introduction
The ORP6040 ORP sensors measure the oxidation-reduction potential of process liquids across a range of −1000 mV to +1000 mV, making it suitable for diverse applications, from wastewater treatment to chemical processing.
As a remarkable pH ORP sensor, it incorporates a high-quality reference electrode system and a Teflon liquid contact junction for enhanced durability and maintenance ease.
Featuring a practical response time of under one minute and a low-noise cable connection for long signal transmission, this sensor from the sensors manufacturer pH ORPmeasurement delivers high precision and good repeatability in demanding operational environments.
Working routine
Understanding how an ORP sensor works helps users appreciate its role in process control and analytical systems:
Step 1: Primary electrode potential formation
The sensor consists of a measuring (active) electrode and a reference electrode. The active electrode interacts with the ions in the liquid medium, while the reference electrode maintains a stable potential. The resulting voltage difference reflects the liquid’s redox state.
Step 2: Electromotive force (EMF) generation
This voltage difference, known as electromotive force (EMF), is generated by the chemical reactions occurring at the interface of the electrodes and the solution. The strength of this EMF corresponds to the relative tendency of the solution to gain or lose electrons (i.e., its oxidation or reduction potential).
Step 3: Signal transmission and measurement
The sensor outputs this potential difference as a millivolt signal (mV), which conductivity transmitters or controllers can read. The measured ORP value provides quantitative feedback on the oxidizing or reducing conditions in the liquid, which can then be utilized for automated process adjustments.
