Modbus Transmitter

Multi-parameter digital Modbus transmitter for real-time general-purpose water quality monitoring and control, measuring key variables such as COD, BOD, TOC, pH, conductivity, dissolved oxygen, etc.

General Description

The wall-mounted multi-parameter digital Modbus transmitter is a centralized control station engineered for continuous water quality monitoring in general-purpose applications. Installed externally and isolated from the fluid, this equipment securely processes and manages data from a comprehensive range of digital sensors. It is the perfect solution for consolidating organic pollution metrics (COD, BOD, TOC), nutrients (Ammonium, Nitrates), traditional physicochemical variables, specific chemical compounds, and biomass indicators.

Its plastic enclosure prevents any form of external environmental corrosion, ensuring an extended operational lifespan in industrial environments when properly shielded from direct sunlight and rain.

Key Features

• Massive Multi-Parameter Capacity: Centralizes critical readings of organic matter, solids, nutrients, disinfectants, and biological pigments into a single device.
• Anti-Corrosion Enclosure: Built from plastic to prevent external corrosion.
• Standard Modbus Protocol: Direct, noise-free integration into PLCs, SCADA systems, and industrial networks via Modbus communication.
• Safe Operation: Fixed wall-mount design (IP65) that keeps the transmitter's electronics fully protected and isolated from direct water contact.
• Local Display & Configuration: Intuitive interface for seamless sensor calibration, system diagnostics, and real-time data reading directly on the factory floor.

Technical Specifications

• Mounting Type: Wall-mount / structural panel installation.
• Communication Interface: Modbus RTU (RS485) / Modbus TCP/IP.
• Protection Grade: IP65 (Installation under a sunshade, canopy, or protective enclosure is highly recommended to avoid direct exposure to sun and rain).
• Enclosure Material: Plastic.
• Supported Parameters:
• Organics & Solids: COD, BOD, TOC, Turbidity, Suspended Solids (SS), TDS, Oil & Hydrocarbons.
• Nutrients & Ions: Ammonium, Nitrates, Chlorides, Calcium.
• Physicochemical & Disinfectants: pH, Conductivity, Dissolved Oxygen, Temperature, Free/Total Chlorine.
• Biomass: Algae, Chlorophyll.

Common Applications

• Industrial process water monitoring and distribution stations.
• Data centralization at the intake and output lines of water treatment plants.
• Environmental control panels for effluent supervision and surface water monitoring.
