Description

The SN-3003-ORP-N01-300T is a fully integrated ORP (Oxidation-Reduction Potential) sensor designed for continuous online monitoring in demanding industrial and environmental applications. Its sensing core utilizes a high-purity platinum composite electrode, which provides exceptional chemical resistance to strong acids, alkalis, and oxidizing agents, ensuring long-term measurement stability and accuracy. The sensor incorporates a built-in temperature probe for automatic temperature compensation, critical for accurate ORP readings across varying environmental conditions.

Housed in a robust, IP68-rated enclosure, the sensor is built for permanent installation in submerged or high-humidity environments, such as wastewater treatment basins, aquaculture tanks, and natural water bodies. The integrated electronics output a standard RS485 signal using the Modbus RTU protocol, allowing direct connection to SCADA systems, PLCs, or data loggers. Its wide operating voltage range simplifies power supply integration in diverse industrial settings.

Key Features

  • High-purity platinum composite electrode for superior chemical durability and measurement precision.
  • Integrated temperature sensor (0-60°C, 0.1°C resolution) for automatic temperature compensation.
  • Industrial RS485 Modbus RTU communication with user-configurable address and baud rate.
  • IP68 waterproof rating ensures reliable operation in fully submerged applications.
  • Wide-range DC power input (7-30V) compatible with standard industrial power supplies.
  • Compact, integrated design simplifies installation and reduces system footprint.
  • Low power consumption (12.5 mA typical) suitable for continuous monitoring systems.
  • Robust construction with braided cable protection for extended field service life.

Applications

  • Continuous online ORP monitoring in industrial wastewater treatment plants (e.g., cyanide, chromium processes).
  • Water quality assessment in natural water bodies like rivers, lakes, and reservoirs.
  • Aquaculture and hydroponics systems for monitoring nutrient oxidation states and disinfection (chlorine) levels.
  • Chemical process control in manufacturing, where redox potential is a critical process variable.
  • Environmental monitoring stations for tracking the health and redox conditions of surface water.

Frequently Asked Questions

What is the communication protocol of this ORP sensor, and how is it configured?

The sensor uses the RS485 physical layer with the Modbus RTU protocol. The communication address and baud rate are user-configurable parameters, allowing you to daisy-chain multiple sensors on a single bus and integrate seamlessly with industrial PLCs, SCADA systems, or data loggers that support Modbus communication.

Can this sensor be used in saltwater or highly corrosive chemical environments?

Yes, the high-purity platinum composite electrode is specifically chosen for its strong resistance to acids, alkalis, and oxidation, making it suitable for harsh environments like industrial wastewater containing cyanide or chromium, as well as saltwater aquaculture. The IP68-rated housing provides additional protection against permanent submersion.

What power supply is required, and how is the sensor wired for power and data?

The sensor operates on a wide-range DC power supply from 7 to 30 volts, making it compatible with standard 12V or 24V industrial systems. Connection is made via the provided industrial cable, which typically includes wires for power (V+, GND) and the differential data pair (A, B) for the RS485 bus. Always refer to the specific wiring diagram for your model.
